## LEDFEEDBACK
|
||
|
||
**Path**: [../src/components/LEDFeedback.h](../src/components/LEDFeedback.h)
|
||
|
||
**Revision History**: Initial documentation
|
||
|
||
This component controls an LED strip (NeoPixel) with various modes like fade, range display, and tri-color blink. It integrates with Modbus for industrial control.
|
||
|
||
## REQUIREMENTS
|
||
|
||
- **Pins**: Data pin for NeoPixel (configurable via `PIN_LED_FEEDBACK`).
|
||
- **Dependencies**:
|
||
- `Adafruit_NeoPixel` library for LED control.
|
||
- ModbusTCP library for communication.
|
||
- `config.h` and `config-modbus.h` for configurations.
|
||
|
||
## FEATURES
|
||
|
||
- Multiple LED modes (OFF, Fade Red-Blue, Range display, Tri-Color Blink).
|
||
- Modbus integration for remote control and monitoring.
|
||
- Configurable LED strip parameters (pin, pixel count, Modbus address).
|
||
|
||
## TODOS
|
||
|
||
- Add more LED modes (e.g., SOLID_COLOR, RAINBOW).
|
||
- Implement brightness control via Modbus.
|
||
- Enhance error handling in Modbus communication.
|
||
|
||
## EXAMPLE
|
||
|
||
```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);
|
||
}
|
||
z[
|
||
{
|
||
Log.errorln(F("LEDFeedback_0 initialization failed."));
|
||
}
|
||
#endif
|
