RS-422 enabled module for bidirectional control of up to 2 TEC modules. Refer to individual directories README for more details.
- 4 NTC temperature sensors
- 2 biderectional TEC drivers (12V input)
- Isolated RS-422 Bus
- STM32F030F4 on board microcontroller
This repository contains
- Altium Designer files
- BOM
- Schematic PDF Gerber files are available in releases
The code in this repository handles the general workflow of the module.
- STM32 Cube MX project
- Makefile
- Source code
- Python script to generate temperature lookup table
To use this code you will need to define the communication protocol between devices (number of bytes, message structure) as well as tune the PID loop for temperature control.
