Hello,
You need to send charachter 'V' then board will response with 6bytes of data.
Format is:
'X','datax','Y',datay,'Z',dataz
(where X,Y,Z are ascii charachters and datax,datay,dataz are raw hex data)
btw. You need to have 38400 baudrate, no parity, 1 stop
If would like to know how to flash start demoboard!?
