# 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)
