## Controllino - Mega

- [Unit Testing](https://docs.platformio.org/en/latest/plus/unit-testing.html?utm_medium=piohome&utm_source=platformio)
- Semiphores : emulated, via ASM noops
- Memory: seems stable with modbus over ethernet

### Omron MX2

- [Programmer](./firmware/OmronMx2.cpp#L460)

### Omron - E5DC

### Calibration

- [TC calibration](https://www.tcdirect.co.uk/product_2_133_21#133/21/1)

# Extrusion Firmware

### Communication modes

- [-] Custom Serial over RS485 (Extruza, 3dtreehouse)
- [- Standard Serial (Lydia-v4.5 - touchscreen/RPI)
- [- Pure RS485 - Slave|Master (In conjunction with injection addon)
- [-] Bluetooth
  - [-] App template
- [ ] TCP 
  - [ ] Modbus (rev 1, base abstract/odel)
  - [ ] ProfiBus (rev 2)
  - [ ] DeviceNet (rev 1)
- [ ] Debug Serial (Always)

### Protocol

- [ ] Internal: add duplex for RS485 feedback
- [-] Add command queue lifecycle / state response
- [-] Handshake
- [- Checksum
- [ ] Broadcast (for bluetooth as well)
- [-] User space / reserved

### Controls

- [ ] Simple cycle control via logic/analog interface
- [ ] Controllino - Mini/Uno version (http://www.kuehlschrankdichtung.de/ | PVC temp and cycle time profile storage) 

### Modbus testing strategy for vendors

- [ ] 1. test basics after unboxing
- [x] 2. programmer test
- [ ] 3. stress/flood test
- [ ] 4. EMI near (scope)
- [ ] 5. EMI long / cable test (serial debugging with scope)

### PID / TC related

- [-] determine barrel empty / full ratio/constant impact on PID readings
- [-] determine actual PID values, independent via calibration devices (see [./firmware/components](./firmware/components) for more)
- [ ] ramp times, window keeping
- [ ] test PVC/PFA [TC cables](https://www.tcdirect.co.uk/product_2_270_1)


## Components

- [ ] Add HMI column
- [ ] Add register range
- [ ] Add wire labels

### Modbus design notes

- each issued read/write has a corrosponding state flag register, eg: issued, proccessing, processed, error code, failure
- use coils only
- when in duplex, feedback channel provides command queue id with state flag, polling should be avoided
- avoid multi bytes/long/strings
- each category shall provide additional user register space
