8Channel EGT-board
This is repository for 8-Channel EGT board. The board is meant to be used in conjuntion with aftermarker engine control units to measure exhaust gas temperatures in invidual cylinders. The PCB is based on eight MAX31855 chips and STM32F103C8T6 bluepill board. The sensors to be used with this need to be K-type EGT sensors with mini K-type thermocouple connectors.
In order to program the bluepill, you will need FTDI breakout board and the code is meant to be used in Arduino IDE. The code should work with regular STM32 core for Arduino, but I had no luck programming it to the bluepill. But using this board manager, the code uploading works: http://dan.drown.org/stm32duino/package_STM32duino_index.json
At this moment the code is unfinished and only capable of reading the EGT sensors and sending data to speeduino through serial bus. See the picture for settings in TS for speeduino. Support for other ecus will be added later using CAN bus.
