tsys01/STM32/TSYS_controller

Firmware for controllers of thermal sensors

Make regular scan of 8 sensors' pairs. USART speed 115200. Code for ../../kicad/stm32

Serial interface commands (ends with '\n'):

• C show coefficients for all thermosensors
• D detect seosors (reseting them)
• H switch I2C to high speed (100kHz)
• L switch I2C to low speed (default, 10kHz)
• R reset both sensors
• T get temperature in degrC

PINOUT

• I2C: PB6 (SCL) & PB7 (SDA)
• USART1: PA9 (Tx) & PA10 (Rx)
• CAN bus: PB8 (Rx), PB9 (Tx)
• USB bus: PA11 (DM), PA12 (DP)
• I2C multiplexer: PB0..PB2 (0..2 address bits), PB12 (~EN)
• sensors' power: PB3 (in, overcurrent), PA8 (out, enable power)
• signal LEDs: PB10 (LED0), PB11 (LED1)
• ADC inputs: PA0 (V12/4.93), PA1 (V5/2), PA3 (I12 - 1V/A), PA6 (V3.3/2)
• controller CAN address: PA13..PA15 (0..2 bits); 0 - master, other address - slave
