- Document conformance to RS-485 electrical standards if used in that context
### RECOMMENDATIONS
- Use pull-up/pull-down resistors on the analog input pins for more reliable readings
- Configure appropriate thresholds in config.h for the specific analog sensors being used
- Implement error handling for the case of both UP and DOWN inputs being active
- Consider adding a debounce mechanism for the switch position to prevent oscillation
## EXAMPLE
This example demonstrates how to initialize and add a Pos3Analog component to your application:
```cpp
#ifdef PIN_POS3_ANALOG_0_UP
pos3Analog_0 = new Pos3Analog(
this, // owner
PIN_POS3_ANALOG_0_UP, // upPin
PIN_POS3_ANALOG_0_DOWN,// downPin
ID_POS3_ANALOG_0, // id
POS3_ANALOG_0_MB_ADDR // modbusAddress
);
if (pos3Analog_0)
{
components.push_back(pos3Analog_0);
Log.infoln(F("Pos3Analog_0 initialized. UpPin:%d, DownPin:%d, ID:%d, MB:%d"),
PIN_POS3_ANALOG_0_UP, PIN_POS3_ANALOG_0_DOWN,
ID_POS3_ANALOG_0, POS3_ANALOG_0_MB_ADDR);
}
else
{
Log.errorln(F("Pos3Analog_0 initialization failed."));
}

description: "Documentation for the AnalogLevelSwitch component, which reads analog inputs as multi-position switches"
keywords: "ESP-32, analog, level switch, multi-position switch, modbus, Arduino, embedded"
---
## Analog Level Switch
**Path**: [`src/AnalogLevelSwitch.cpp`](../src/AnalogLevelSwitch.cpp)
**Revision History**: Initial documentation
The Analog Level Switch component reads an analog input pin and interprets the voltage as a discrete position or "slot". This is useful for interfacing with multi-position switches, potentiometers, or resistor networks connected to an analog input. The component provides smooth reading with configurable debouncing, hysteresis, and auto-calibration for reliable slot detection.
## REQUIREMENTS
- An analog input pin connected to a voltage divider circuit
- Appropriate resistor selection for desired voltage levels (detailed guidance provided in header file)
## FEATURES
- Converts analog readings into discrete position slots
- Configurable number of positions/slots (up to 32 by default)
- Adjustable ADC value offset and step size per slot
- Smoothing with moving average or exponential moving average
- Configurable debouncing and hysteresis to prevent position flickering
- Modbus integration with registers for current level and raw values
- Individual slot state monitoring as Modbus coils
## DEPENDENCIES
- [ArduinoLog](https://github.com/thijse/Arduino-Log) - For logging capabilities
- [Component](../src/Component.h) - Base component class
- [ModbusTCP](../src/modbus/ModbusTCP.h) - For Modbus communication
```mermaid
graph TD
AnalogLevelSwitch --> Component
AnalogLevelSwitch --> ModbusTCP

```
## BEHAVIOUR
The AnalogLevelSwitch reads the analog input at regular intervals, applies smoothing, debouncing, and then maps the analog value to a discrete slot.

```
## TODOS
### PERFORMANCE
- Review smoothing algorithm choice based on application requirements (MA vs EMA)
- Consider using hardware filtering for high-noise environments
- Optimize ADC reading intervals based on use case
### SECURITY
- Validate Modbus access controls to prevent unauthorized writes
- Consider adding range validation for configuration parameters
### COMPLIANCE
- Ensure ADC readings are within the ESP-32's input voltage specifications
- Review compliance with relevant industrial standards if used in regulated environments
### RECOMMENDATIONS
- For optimal performance, use 1% or better tolerance resistors in voltage divider
- Keep equivalent resistance of voltage divider relatively low (1k-100k range) to ensure ADC accuracy
- Be mindful of resistor tolerance and ADC non-linearity when designing circuits
- Use the resistor calculation guidance in the header file to design appropriate circuits
## EXAMPLE
```cpp
#ifdef PIN_ANALOG_LEVEL_SWITCH
analogLevelSwitch = new AnalogLevelSwitch(
this, // owner
PIN_ANALOG_LEVEL_SWITCH, // analogPin
ALS_NUMBER_OF_LEVELS, // numLevels
ALS_LEVEL_STEP, // levelStep
ALS_ADC_VALUE_OFFSET, // adcValueOffset
ID_ANALOG_LEVEL_SWITCH, // id
ALS_MODBUS_ADDR // modbusAddress
);
if (analogLevelSwitch)
{
components.push_back(analogLevelSwitch);
Log.infoln(F("AnalogLevelSwitch initialized. Pin:%d, Levels:%d, Step:%d, Offset:%d, ID:%d, MB:%d"),
PIN_ANALOG_LEVEL_SWITCH, ALS_NUMBER_OF_LEVELS, ALS_LEVEL_STEP,
ALS_ADC_VALUE_OFFSET, ID_ANALOG_LEVEL_SWITCH, ALS_MODBUS_ADDR);
}
else
{
Log.errorln(F("AnalogLevelSwitch initialization failed."));
}
#endif
```

## TODOS
### PERFORMANCE
- Consider adaptive filtering based on rate of change for better response characteristics
- Explore efficient normalization techniques to handle different ADC resolutions (10-bit vs 12-bit)
- Implement more sophisticated filtering algorithms if needed for high-noise environments
### SECURITY
- Add bounds checking for remote control values to prevent overflow/underflow conditions
- Implement authentication for remote control mode changes in security-sensitive applications
- Consider adding fail-safe behavior for loss of Modbus communication
### COMPLIANCE
- Verify compliance with IEC 61131-3 for industrial control systems
- Ensure Modbus implementation follows Modbus specification guidelines
- Document EMC considerations for analog input circuits
### RECOMMENDATIONS
- Use a hardware RC low-pass filter as suggested in the component comments for noisy environments
- Select appropriate damping algorithm based on application needs:
- NONE: Fast response but noisy
- MOVING_AVERAGE: Good balance of smoothing and responsiveness
- EMA: Smooth response with less memory requirements
- Adjust deadband (POT_DEADBAND) based on the stability requirements of the application
## EXAMPLE
This example demonstrates how to initialize a POT component with moving average filtering:
```cpp
#ifdef PIN_POT_SPEED
potSpeed = new POT(
this, // owner
PIN_POT_SPEED, // pin
ID_POT_SPEED, // id
POT_SPEED_MB_ADDR, // modbusAddress
POTDampingAlgorithm::DAMPING_MOVING_AVERAGE // filtering algorithm
);
if (potSpeed)
{
components.push_back(potSpeed);
Log.infoln(F("POT Speed initialized. Pin:%d, ID:%d, MB:%d"),
PIN_POT_SPEED, ID_POT_SPEED, POT_SPEED_MB_ADDR);
}
else
{
Log.errorln(F("POT Speed initialization failed."));
}
#endif
```
### References
The component implements several filtering techniques for noise reduction:
- **Moving Average**: Implemented as an incremental ring buffer with O(1) complexity
- **Exponential Moving Average (EMA)**: Uses a 1-pole IIR filter with the formula: `y[n] = y[n-1] + (x[n] - y[n-1]) / 2^k`
The hardware recommendations include an RC low-pass filter with the potentiometer itself serving as the resistor, and suggested capacitor values based on desired cutoff frequencies:
- For faster response (~30 Hz): Use 1 μF
- For moderate filtering (~10 Hz): Use 2.2 μF or 3.3 μF
- For more smoothing (~5 Hz): Use 4.7 μF or 6.8 μF

```mermaid
graph TD
Application --> SakoModbusRegisters
SakoModbusRegisters --> ModbusClient
ModbusClient --> RS485Hardware
```
## BEHAVIOUR
The component provides enumeration constants that map to specific Modbus registers in the Sako VFD. It doesn't implement any behavior itself but provides the addressing information needed for the application to communicate with the device.
```mermaid
sequenceDiagram
Application->>ModbusClient: Use Register Address from E_SAKO_PARAM
ModbusClient->>SakoVFD: Send Modbus Request
SakoVFD->>ModbusClient: Send Register Data
ModbusClient->>Application: Return Result
```
## TODOS
### PERFORMANCE
- Consider organizing registers into separate enum classes for different parameter groups
- Evaluate if a more structured approach like a map or class with methods would improve usability

- Consider implementing a higher-level interface that uses these enum values but provides type safety and validation
## EXAMPLE
```cpp
// Example of using the Sako register enums with a Modbus client
ModbusClient* modbusClient = new ModbusClient(
&Serial2,
PIN_RS485_DE_RE,

- Inherits from `Component` base class
## FEATURES
- Register component member functions for remote invocation
- Message routing between components
- Method lookup by component ID and method name
- Debug support for listing registered methods
- Support for component discovery for Modbus management
## DEPENDENCIES

alt Method found
Bridge->>Component: Invoke method
Component-->>Bridge: Return result
Bridge-->>Caller: Return result
else Method not found
Bridge-->>Caller: Return E_NOT_FOUND
end
else Other verbs
Bridge-->>Caller: Return E_OK
end
```
## TODOS
### PERFORMANCE

Initialized --> Comparing: update(newValue)
Comparing --> ThresholdNotMet: Below threshold
Comparing --> ThresholdExceeded: Above threshold
ThresholdNotMet --> ValueUpdated: Update value without notification
ThresholdExceeded --> NotifyOwner: Send Modbus update
NotifyOwner --> CallbackExecution: Execute post-notification callback
CallbackExecution --> ValueUpdated: Value updated
ValueUpdated --> Initialized: Ready for next update
```
## TODOS
### PERFORMANCE
- Consider providing specialized implementations for common types to avoid template instantiation overhead
- Investigate using std::variant for better type safety and potentially reduced memory footprint
- Add an optional hysteresis parameter to prevent rapid oscillations around threshold values

It avoids using the standard library, making it suitable for resource-constrained environments.
## REQUIREMENTS
- No specific hardware pins required
- C++17 support
- Arduino framework or equivalent (`millis()` function)
## PROVIDES
- `Timer<size_t max_tasks, unsigned long (*time_func)()>` - Main timer class template
- `handler_t` - Function pointer type for task callbacks
- `timer_create_default()` - Utility function to create a timer with default settings
- `task` struct - Internal structure to represent scheduled tasks
## FEATURES
- Schedule tasks to run after a specified delay
- Schedule tasks to run at specific time points
- Schedule recurring tasks at regular intervals
- Configurable number of maximum concurrent tasks
- Customizable time function (defaults to `millis()`)
- Small memory footprint with fixed-size task array
- No dynamic memory allocation
## DEPENDENCIES
- [`src/modbus/macros.h`](../src/modbus/macros.h)
- Arduino core (`Arduino.h` or `WProgram.h` for older versions)
```mermaid
graph TD
XTimer --> Macros
XTimer --> Arduino["Arduino Core"]
```
## BEHAVIOUR
The timer operates by tracking tasks and their scheduled execution times:
```mermaid
graph TD
Start[Initialize Timer] --> AddTask[Add Task to Queue]
AddTask --> Tick[Timer Tick]
Tick --> CheckTasks[Check Task Expiry]
CheckTasks --> TaskExpired{Task Expired?}
TaskExpired -- Yes --> Execute[Execute Task Handler]
TaskExpired -- No --> Tick
Execute --> IsRepeat{Is Recurring?}
IsRepeat -- Yes --> ResetTask[Reset Timer for Next Run]
ResetTask --> Tick
IsRepeat -- No --> RemoveTask[Remove Task from Queue]
RemoveTask --> Tick
```
## TODOS
### PERFORMANCE
- Consider a more efficient data structure than a simple array for tasks, especially for systems with many scheduled tasks
- Implement a priority queue to optimize the `tick()` function when handling many tasks
- Provide options to reduce memory usage for systems with very limited RAM
### SECURITY
- No major security concerns as this is a local timer implementation
- Ensure task handlers do not introduce timing vulnerabilities in security-critical applications
### COMPLIANCE
- Review for MISRA C++ compliance if used in safety-critical applications
- Ensure thread safety if used in multi-threaded environments
### RECOMMENDATIONS
- Keep task handlers lightweight to avoid blocking the main loop
- Avoid using too many concurrent tasks as it may impact performance
- For time-critical operations, consider using hardware timers instead
- When using the `every()` function for periodic tasks, be aware of potential timing drift over long periods
- Consider implementing a task ID return value to allow for cancellation of scheduled tasks

# CircularLogPrinter
**Path**: [`src/Logger.h`](../src/Logger.h)
**Revision History**: Initial documentation
CircularLogPrinter is a high-performance, thread-safe logging utility designed for ESP32 applications. It maintains a configurable circular buffer of log messages in memory while optionally mirroring output to a Serial or other Print-compatible stream. The implementation is compliant with MISRA/CPPCHECK standards, avoiding reinterpret casts for improved safety.
## Requirements
### Hardware
- No specific hardware pins required
- Compatible with ESP32 platforms
### Software
- Arduino framework
- FreeRTOS (for thread-safety features)
- ESP-IDF (for ESP log integration)
## Features
- Configurable circular buffer for storing the last N log lines
- Thread-safe operation (optional via configuration)
- Ability to redirect ESP-IDF logging macros (ESP_LOGx) into this printer
- MISRA/CPPCHECK compliant implementation with no pointer type casting
- Memory-efficient design with fixed buffer sizes
- Optional output mirroring to any Arduino Print-compatible stream
## Dependencies
- [Arduino.h](https://github.com/arduino/ArduinoCore-avr/blob/master/cores/arduino/Arduino.h)
- [Print.h](https://github.com/arduino/ArduinoCore-avr/blob/master/cores/arduino/Print.h)
- [esp_log.h](https://github.com/espressif/esp-idf/blob/master/components/log/include/esp_log.h)
```mermaid
graph TD
CircularLogPrinter --> Print
CircularLogPrinter --> Arduino
CircularLogPrinter --> esp_log
```
## Behaviour
The CircularLogPrinter maintains a circular buffer of log lines. When the buffer is full, new log entries overwrite the oldest entries. Log entries are committed when a newline character is encountered or when the maximum line length is reached.
```mermaid
stateDiagram-v2
[*] --> Initialize: Constructor
Initialize --> Ready
Ready --> AppendChar: write(byte)
Ready --> AppendMultipleChars: write(buffer, size)
AppendChar --> CommitLine: If newline
AppendChar --> AppendChar: If not newline
AppendMultipleChars --> CommitLine: If newline encountered
AppendMultipleChars --> Ready: After processing
CommitLine --> Ready
Ready --> Clear: clear() called
Clear --> Ready
```
## TODOs
### Performance
- Consider using a more efficient memory layout for the circular buffer
- Evaluate the impact of thread-safety mechanisms on performance in high-frequency logging scenarios
- Add compile-time options to disable features not needed for specific applications
### Security
- Add configurable log level filtering to prevent sensitive information leakage
- Consider adding encryption options for logs containing sensitive information
- Implement log rotation to persistent storage for critical deployments
### Compliance
- The implementation is already MISRA/CPPCHECK compliant by avoiding pointer type casting
- Consider adding support for standardized log formats like RFC5424
### Recommendations
- Use reasonable buffer sizes to avoid excessive memory usage
- Consider the performance impact of thread-safety in high-frequency logging scenarios
- When using with ESP-IDF logging, ensure consistent configuration across components
- For production environments, implement a strategy for persistent log storage
## Example
This example shows how to initialize and use the CircularLogPrinter:
```cpp
// Create a CircularLogPrinter that mirrors to Serial
CircularLogPrinter logger(&Serial);
// Clear the buffer
logger.clear();
// Write some logs
logger.println("Starting application...");
logger.printf("System initialized with version: %s", VERSION);
// Attach to ESP-IDF logging
logger.attachToEspLog();
// Now ESP_LOGx macros will also be captured
ESP_LOGI("TAG", "This will be captured by the CircularLogPrinter");
// Retrieve a specific line from history (0 is most recent)
const char* lastLine = logger.getLine(0);
```

## Component
**Path**: [src/Component.h](../src/Component.h)
**Revision History**: Initial documentation
The Component class serves as the foundational base class for all hardware and software components in the system. It provides a standardized interface for component initialization, runtime behavior, and communication with other system components. The class implements a modular architecture that allows components to be easily added, removed, or modified without affecting the rest of the system.
## REQUIREMENTS
- Arduino framework
- ESP32 platform
- WString.h for string handling
- ArduinoLog.h for logging functionality
- Vector.h for dynamic arrays
## FEATURES
- Component identification with unique IDs and names
- Standardized initialization and setup processes
- Runtime flags for controlling component behavior
- Owner-child component relationship hierarchy
- Integration with Modbus communication
- Network capability flags
## DEPENDENCIES

- [ArduinoLog.h](https://github.com/thijse/Arduino-Log)
- [Vector.h](https://github.com/janelia-arduino/Vector)
- [enums.h](../src/enums.h)
- [constants.h](../src/constants.h)
- [error_codes.h](../src/error_codes.h)
- [macros.h](../src/macros.h)
- [xtypes.h](../src/xtypes.h)
```mermaid

Component --> ModbusBlockView[ModbusBlockView class]
Component --> MB_Registers[MB_Registers class]
Component --> RS485[RS485 class]
```
## BEHAVIOUR
The Component class follows a lifecycle pattern that includes initialization, setup, and runtime phases. Components can be dynamically enabled or disabled through runtime flags.
```mermaid
stateDiagram-v2
[*] --> Constructed
Constructed --> Setup: setup()
Setup --> Running: flags & E_OF_SETUP
Running --> LoopExecution: flags & D_OF_LOOP
LoopExecution --> Running
Running --> Disabled: disable()

- Use the owner-child relationship to implement clean component lifecycle management
## EXAMPLE
This section illustrates how to create and configure a Component instance. Since the complete implementation in Component.cpp is not accessible, this example provides a general pattern for component creation based on the header file.
```cpp
// Create a basic component with default settings
Component* basicComponent = new Component("BasicComponent", 100, Component::COMPONENT_DEFAULT);
// Add the component to the components vector
if (basicComponent) {
components.push_back(basicComponent);
Log.infoln(F("Basic component initialized. ID:%d"), 100);
} else {
Log.errorln(F("Basic component initialization failed."));
}
// Example with an owner component
Component* parentComponent = new Component("ParentComponent", 200, Component::COMPONENT_DEFAULT);
Component* childComponent = new Component(
"ChildComponent", // name
201, // id
Component::COMPONENT_DEFAULT, // flags
parentComponent // owner
);
if (childComponent) {
components.push_back(childComponent);
Log.infoln(F("Child component initialized. Name:%s, ID:%d"),
"ChildComponent", 201);
} else {
Log.errorln(F("Child component initialization failed."));
}
```

# ModbusLogicEngine
**Path**: [`src/components/ModbusLogicEngine.h`](../src/components/ModbusLogicEngine.h)
**Revision History**: Initial documentation
The ModbusLogicEngine component provides a programmable logic rule engine that executes conditional actions based on Modbus register values. It functions similar to a basic PLC (Programmable Logic Controller), allowing the system to be configured with a set of if-then rules via Modbus registers without requiring firmware modifications.
## REQUIREMENTS
### Hardware
- No specific hardware pins required
- Operates entirely on Modbus data
### Software
- Requires `ENABLE_MB_SCRIPT` to be defined in the configuration
- Access to Modbus register data (holding registers, coils, etc.)
- PHApp instance to interact with other components
## FEATURES
- Supports up to 8 configurable logic rules (adjustable via `MAX_LOGIC_RULES`)
- Each rule includes:
- A condition based on Modbus register or coil values
- An action to execute when the condition is met
- Status tracking (trigger count, last execution time, etc.)
- Condition types: equal, not equal, less than, less or equal, greater than, greater or equal
- Action types:
- Write to a Modbus holding register
- Write to a Modbus coil
- Call a registered component method
- Rule debugging capabilities via flags
- Rules are fully configurable via Modbus registers
## DEPENDENCIES
- [Component](../src/Component.h)
- [ArduinoLog](https://github.com/thijse/Arduino-Log)
- [config.h](../src/config.h)
- [ModbusTypes.h](../src/modbus/ModbusTypes.h)
```mermaid
graph TD
ModbusLogicEngine --> Component
ModbusLogicEngine --> PHApp
ModbusLogicEngine --> ArduinoLog
ModbusLogicEngine --> ModbusTypes
```
## BEHAVIOUR
The ModbusLogicEngine evaluates rules at regular intervals (default 100ms). For each enabled rule:
```mermaid
graph TD
A[Check if rule enabled] -->|Yes| B[Read condition source value]
B --> C[Evaluate condition]
C -->|Condition true| D[Execute action]
D --> E[Update status registers]
C -->|Condition false| E
A -->|No| F[Skip rule]
F --> E
```
Each rule occupies a block of 13 consecutive Modbus registers with the following structure:
1. Enabled (0/1)
2. Condition Source Type (register type)
3. Condition Source Address (Modbus address)
4. Condition Operator (0=Equal, 1=Not Equal, 2=Less Than, etc.)
5. Condition Value (to compare against)
6. Command Type (2=Write Coil, 3=Write Register, 100=Call Method)
7. Command Target (address or component ID)
8. Command Parameter 1 (value or method ID)
9. Command Parameter 2 (additional argument)
10. Flags (debug settings)
11. Last Status (execution result code)
12. Last Trigger Timestamp
13. Trigger Count
## TODOS
### PERFORMANCE
- Consider optimizing the rule evaluation frequency based on application needs
- Implement priority levels for rules to ensure critical rules execute first
- Add rate limiting options for high-frequency triggers
### SECURITY
- Implement range checking on Modbus addresses to prevent unauthorized memory access
- Add authorization mechanism for registering and modifying component methods
- Consider adding CRC or checksum validation for rule configurations
### COMPLIANCE
- Document compatibility with IEC 61131-3 (PLC programming standard) concepts
- Add options for meeting real-time response requirements for industrial control systems
### RECOMMENDATIONS
- Use debug flags during initial rule setup and disable for production
- Organize rule addresses logically to group related functionality
- Implement a backup/restore mechanism for rule configurations
- Consider adding a web interface for easier rule configuration
## EXAMPLE
This section would typically show how the component is constructed and mounted, but the CPP file couldn't be located. However, based on the header file, a typical initialization would look like:
```cpp
#ifdef ENABLE_MB_SCRIPT
// Create the ModbusLogicEngine component
modbusLogicEngine = new ModbusLogicEngine(this); // 'this' is PHApp instance
if (modbusLogicEngine)
{
components.push_back(modbusLogicEngine);
// Register methods that can be called by logic rules
modbusLogicEngine->registerMethod(
COMPONENT_KEY_RELAY_0, // component ID
1, // method ID for toggle
[this](short arg1, short arg2) -> short {
// Method implementation
return 0; // Success
}
);
Log.infoln(F("ModbusLogicEngine initialized"));
}
else
{
Log.errorln(F("ModbusLogicEngine initialization failed"));
}
#endif

# POT
**Path**: [src/components/POT.h](../src/components/POT.h)
**Revision History**: Initial documentation
The POT component provides an analog potentiometer reader with lightweight digital filtering. It's designed for small AVR/ESP32 class MCUs with no dynamic memory allocation and no floating-point operations. The component supports local and remote control modes, making it ideal for industrial applications with Modbus integration.
## REQUIREMENTS
### Hardware
- Analog input pin connected to a potentiometer wiper
- Recommended: RC low-pass filter (using the potentiometer as R and adding a capacitor)
### Software
- Arduino framework
- ArduinoLog library
- Modbus TCP implementation
## FEATURES
- Three damping modes:
- NONE (raw readings)
- MOVING-AVERAGE (box-car filter with O(1) implementation)
- EMA (Exponential Moving Average with 1-pole IIR filter)
- Dead-band implementation to suppress ±1-LSB chatter after scaling
- Scaling from raw ADC values (0-4095 for ESP32) to application values (0-100 by default)
- Local/Remote control modes via Modbus
- Efficient implementation with no dynamic memory allocation
- Configurable sampling interval and filter parameters
## DEPENDENCIES
- [Component](../src/Component.h) - Base component class
- [Arduino](https://www.arduino.cc/reference/en/) - Core Arduino framework
- [ArduinoLog](https://github.com/thijse/Arduino-Log) - Logging functionality
- [ModbusTCP](../src/modbus/ModbusTCP.h) - Modbus TCP implementation
```mermaid
graph TD
POT --> Component
POT --> ArduinoLog
POT --> ModbusTCP
Component --> ArduinoLog
```
## BEHAVIOUR
The POT component reads analog values at a configurable interval, applies filtering based on the selected algorithm, and exposes the value through Modbus registers. It supports two control modes: Local (reading from the physical potentiometer) and Remote (accepting values through Modbus).

```
## TODOS
### PERFORMANCE
- Consider implementing interrupt-based sampling for more precise timing
- Evaluate filter performance with high-frequency noise
- Profile performance impact of different filter algorithms on various platforms
### SECURITY
- Add range validation for Modbus-supplied remote values
- Consider authentication for mode switching between local and remote control
- Implement rate limiting for remote value changes
### COMPLIANCE
- Verify ADC reading methods across different platforms for consistent behavior
- Ensure proper error handling for edge cases (e.g., disconnected potentiometer)
- Document requirements for electrical compliance (input voltage ranges, etc.)
### RECOMMENDATIONS
- Use the hardware RC filter recommendation provided in the component header:
- For 5kΩ potentiometer: Add 1-3.3µF capacitor between wiper and ground
- Adjust capacitor value based on desired cutoff frequency and noise conditions
- Start with the EMA filter for most applications as it provides good smoothing with minimal resources
- For applications requiring precise readings, increase the sampling rate and adjust the filtering parameters
## EXAMPLE
This example shows how to initialize and use a POT component with an ESP32:
```cpp
#ifdef PIN_ANALOG_0
pot_0 = new POT(
this, // owner
PIN_ANALOG_0, // pin
COMPONENT_KEY_ANALOG_0, // id
MB_ANALOG_0, // modbusAddress
POTDampingAlgorithm::DAMPING_EMA // filtering algorithm
);
if (pot_0)
{
components.push_back(pot_0);
Log.infoln(F("POT_0 initialized. Pin:%d, ID:%d, MB:%d"),
PIN_ANALOG_0, COMPONENT_KEY_ANALOG_0, MB_ANALOG_0);
}
else
{
Log.errorln(F("POT_0 initialization failed."));
}
#endif
```

#ifdef ENABLE_SERIAL_COMMANDS
serialMessage = new SerialMessage(
Serial, // stream (Hardware Serial)
this // owner component
);
if (serialMessage)
{
components.push_back(serialMessage);
Log.infoln(F("SerialMessage initialized. Stream: Hardware Serial"));
}
else
{
Log.errorln(F("SerialMessage initialization failed."));
}
#endif
// Alternative with Serial1 for RS485 communication
#ifdef ENABLE_RS485_SERIAL
rs485SerialMessage = new SerialMessage(
Serial1, // stream (Hardware Serial1)
this // owner component
);
if (rs485SerialMessage)
{
components.push_back(rs485SerialMessage);
Log.infoln(F("RS485 SerialMessage initialized. Stream: Hardware Serial1"));
}
else
{
Log.errorln(F("RS485 SerialMessage initialization failed."));
}
#endif
```
### Message Handling Example
```cpp
// Owner component implements onMessage to handle parsed commands
void MyComponent::onMessage(uint16_t id, uint8_t verb, uint8_t flags,
const String& payload, Component* sender)
{
if (sender == serialMessage)
{
Log.infoln(F("Received serial command: ID=%d, Verb=%d, Payload=%s"),
id, verb, payload.c_str());
// Process the command based on ID and verb
switch (id)

StatusLight --> ModbusTCP
```
## Behaviour
The StatusLight component manages a digital output pin with three possible states: OFF, ON, and BLINKING. When in BLINKING state, it toggles the output at the configured interval.
```mermaid
stateDiagram-v2
[*] --> OFF
OFF --> ON: set(1)
ON --> OFF: set(0)
OFF --> BLINK: status_blink(true)
ON --> BLINK: status_blink(true)

```cpp
#ifdef STATUS_WARNING_PIN
StatusLight* warningLight = new StatusLight(
this, // owner
STATUS_WARNING_PIN, // pin
COMPONENT_KEY_FEEDBACK_0, // id
MB_MONITORING_STATUS_FEEDBACK_0 // modbusAddress
);
if (warningLight)
{
components.push_back(warningLight);
Log.infoln(F("Warning Status Light initialized. Pin:%d"), STATUS_WARNING_PIN);
}
else
{
Log.errorln(F("Warning Status Light initialization failed."));
}
#endif
// Later in the code, control the status light:
warningLight->on(); // Turn on the light
warningLight->off(); // Turn off the light
warningLight->setBlink(true); // Make it blink

components.push_back(stepperController_0);
Log.infoln(F("StepperController_0 initialized. Dir:%d, Pulse:%d, Speed:%d"),
PIN_STEPPER_0_DIR, PIN_STEPPER_0_PULSE, STEPPER_0_SPEED);
}
else
{
Log.errorln(F("StepperController_0 initialization failed."));
}

## Configuration System
**Path**: [src/config.h](../src/config.h)
**Revision History**: Initial documentation
The configuration system is a centralized header file containing all global settings, pin definitions, platform-specific configurations, and feature flags. It provides a unified interface for configuring hardware dependencies, communication protocols, and enabling/disabling various features of the firmware.
## REQUIREMENTS
- ESP-32 microcontroller (with support for other platforms like Portenta H7, Controllino Mega)
- Platform.io development environment
- Configuration is designed to work with Modbus-485 protocol for industrial applications
## FEATURES
- Automatic platform detection (ESP32, Portenta H7, Controllino Mega, Arduino Uno)
- Component ID enumeration for consistent system-wide component identification
- Configurable GPIO pin assignments for various peripherals
- Network configuration for WiFi in both station and access point modes
- Modbus TCP and RS485 communication settings
- Temperature profile and signal plotting configuration
- Customizable debugging and logging options
- Feature flags for enabling/disabling system components
## DEPENDENCIES
- [Arduino.h](https://www.arduino.cc/reference/en/) - Core Arduino library
- [config_adv.h](../src/config_adv.h) - Advanced configuration settings
- [stdint.h](https://en.cppreference.com/w/cpp/header/cstdint) - Standard integer types
```mermaid
graph TD
config[config.h] --> arduino[Arduino.h]
config --> configadv[config_adv.h]
config --> stdint[stdint.h]
config --> platformlibs[Platform-specific Libraries]
```
## BEHAVIOUR
The configuration system is a static definition file that controls the behavior of the firmware at compile time. It doesn't have runtime behavior itself, but dictates which components are initialized and how they operate.
```mermaid
graph TD
Config[Configuration System] --> PlatformDetection[Platform Detection]
Config --> ComponentIDs[Component ID Assignment]
Config --> FeatureFlags[Feature Flags]
FeatureFlags --> EnabledComponents[Enabled Components]
FeatureFlags --> DisabledComponents[Disabled Components]
Config --> NetworkSettings[Network Settings]
Config --> PinAssignments[Pin Assignments]
```
## TODOS
### PERFORMANCE
- Consider separating platform-specific configurations into dedicated files
- Evaluate the impact of enabled debugging flags on performance
- Review pin assignment efficiency for optimal GPIO usage
### SECURITY
- WiFi credentials are hardcoded - implement secure storage or configuration mechanism
- Consider encryption for sensitive communications
- Review and secure default access point settings
### COMPLIANCE
- Review for compliance with industrial standards
- Consider adding provisions for safety-critical systems where applicable
- Document electrical specifications for compliance with relevant regulations
### RECOMMENDATIONS
- Use preprocessor guards when modifying to ensure backward compatibility
- When adding new components, follow the existing ID assignment pattern
- Consider implementing a runtime configuration system to complement static definitions
- Separate network credentials into a separate secure file
## EXAMPLE
The configuration system is used primarily as an include in other components. For example, when initializing an LED Feedback component:
```cpp
#ifdef PIN_LED_FEEDBACK_0
ledFeedback_0 = new LEDFeedback(
this, // owner
PIN_LED_FEEDBACK_0, // pin
LED_PIXEL_COUNT_0, // pixelCount
ID_LED_FEEDBACK_0, // id
LED_FEEDBACK_0_MB_ADDR // modbusAddress
);
if (ledFeedback_0)
{
components.push_back(ledFeedback_0);
Log.infoln(F("LEDFeedback_0 initialized. Pin:%d, Count:%d, ID:%d, MB:%d"),
PIN_LED_FEEDBACK_0, LED_PIXEL_COUNT_0,
ID_LED_FEEDBACK_0, LED_FEEDBACK_0_MB_ADDR);
}
else
{
Log.errorln(F("LEDFeedback_0 initialization failed."));
}
#endif
```

staticJsonDocument<512> doc;
DeserializationError error = deserializeJson(doc, jsonStr);
if (error) {
Log.errorln("Failed to parse JSON: %s", error.f_str());
return;
}
// Default values
uint32_t baudRate = 115200;
uint8_t retryCount = 3;
bool debugEnabled = false;
// Safe parsing with default fallback
parseJsonFieldUint32(doc, "baud_rate", baudRate, "Baud Rate", "Settings");
parseJsonFieldUint8(doc, "retry_count", retryCount, "Retry Count", "Settings");
parseJsonFieldBool(doc, "debug_enabled", debugEnabled, "Debug Enabled", "Settings");
// Use the parsed values
Log.infoln(F("Settings loaded: Baud=%lu, Retry=%d, Debug=%s"),
baudRate, retryCount, debugEnabled ? "YES" : "NO");
}

- AP (Access Point) configuration management
- Conditional APSTA mode support
- JSON serialization/deserialization
- IP address, gateway, and DNS configuration
- Configuration loading from file/storage
- Debugging and logging support
## DEPENDENCIES
- [config.h](config.h)
- [enums.h](enums.h)
- [Logger.h](Logger.h)
- [ArduinoJson](https://arduinojson.org/)
- [ArduinoLog](https://github.com/thylakoid/213-arduino-logger)
## TODOS
### PERFORMANCE
- Implement memory efficient JSON handling
- Optimize IP address parsing
- Add caching mechanism for settings
### SECURITY
- Implement password encryption
- Add input validation for IP addresses
- Implement secure configuration storage
- Add configuration bup and restore functionality
### COMPLIANCE
- Verify WiFiAlliance compliance
- Implement industrial WiFi best practices
- Add network security protocol support
## EXAMPLE
Here an example how such component is being constructed and mounted:
```cpp
// Initialize WiFi settings
WiFiNetworkSettings wifiSettings;
// Load settings from JSON configuration
If (LittleFS.exists("/network.json")) {
File configFile = LittleFS.open("/network.json", "r");
DynamicJsonDocument doc(1024);
deserializeJson(doc, configFile);
configFile.close();
wifiSettings.loadSettings(doc.as<JsonObject>());
}
// Configure WiFi based on settings
WiFi.config(
wifiSettings.sta_local_IP,
wifiSettings.sta_gateway,
wifiSettings.sta_subnet,
wifiSettings.sta_primary_dns,
wifiSettings.sta_secondary_dns
);
WiFi.begin(
wifiSettings.sta_ssid.c_str(),
wifiSettings.sta_password.c_str()
);
// In AP_STA moftAPAPaT mode, also configure AP
#ifdef ENABLE_AP_STA
WiFi.softAP(
wifiSettings.ap_ssid.c_str(),
wifiSettings.ap_password.c_str()
);
WiFi.softAPConfig(
wifiSettings.ap_config_ip,
wifiSettings.ap_config_gateway,
wifiSettings.ap_config_subnet
);
#endif
// Print current configuration
wifiSettings.print();
```

* =====================================================================================
* EXAMPLE USAGE (POC)
* =====================================================================================
* To disable a feature at compile-time, add e.g. `-DNETWORKVALUE_ENABLE_LOGGING=0` to build_flags.
* To disable a feature at runtime, use the new API.
* =====================================================================================
* In TemperatureProfile.h:
*
* #include "NetworkValue.h"
*
* using StatusValue = NetworkValue<PlotStatus>;
*
* // ...
*
* =====================================================================================
* In TemperatureProfile.cpp constructor:
*
* // Instantiate with only Modbus and Notify features enabled at runtime
* _statusValue(this, this->id, "TProf Status",
* static_cast<uint8_t>(NetworkValueFeatureFlags::MODBUS) |
* static_cast<uint8_t>(NetworkValueFeatureFlags::NOTIFY));
*
* // Configure the enabled features
* _statusValue.initNotify(...);
* _statusValue.initModbus(...);
* _statusValue.initLogging(true);
*
* // You can also toggle features later
* _statusValue.enableFeature(NetworkValueFeatureFlags::LOGGING);
*
