Sensor protocol

Baud rate

The firmware should detect the baud rate. Common baud rates are ~23000 (STM32) and ~51000 (YST GD32)

data recieved from the sensors is between 6 bytes and 10 bytes.

Analysis of data send TO the sensor boards:

On a 23000 baud board:

data for 'calibrate':

1E0 000 000 060 000 000

'normal' data: 108 000 000 000 000 000

word 1 - unknown

word 2 - flashcount

word 3 - calibrate - 0x00 or 0x60
