Check temperature on sensors pair and show values of T measured by USART.
USART speed 115200. Code for NUCLEO-042
Serial interface commands (ends with '\n'):
- C show coefficients for both 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: PA9 (SCL) & PA10 (SDA)
- USART2: PA2 (Tx) & PA15 (Rx)
