Sensor data serial bridge

This is a simple initial version of a micro:bit C++ programme to receive accelerometer data via radio and bridge it to a computer via serial.

In its current initial state it needs some basic configuration and it sends the data from the current micro:bit in the following format:

P[12345678]AX[408]AY[748]AZ[-1288]BA[0]BB[1]
P[12345679]AX[520]AY[-172]AZ[-448]BA[0]BB[1]
P[1234567A]AX[-412]AY[436]AZ[340]BA[0]BB[1]
P[1234567B]AX[-408]AY[504]AZ[-788]BA[0]BB[1]
P[1234567C]AX[-480]AY[592]AZ[-736]BA[0]BB[1]

Where:

• P = Unique identifier of the protocol message
• AX = Accelerometer X axis
• AY = Accelerometer X axis
• AZ = Accelerometer X axis
• BA = Button A state
• BB = Button B state

More information about the protocol will be defined soon.
