Ive been testing this software with the help of the author to add serial output to an Arduino, which at the moment drives a row of leds, but this could also be an LCD display.
Baud rate at the moment is fixed at 57000 8n1
He has suggested this coding method to represent the drive letters and read write states:
5bits for A-Z and 2bits to represent four states (with zero) 0=idle, 01=read, 10=write, 11=read+write
Opinions and/or suggestions please.
