Hi all, I am trying to use a 8051 to read a PS2 device(a PS2 BarCode Reader). But I am completely new to the PS2 interface. Are there any exisiting source codes and hardware samples for similar applications? It would be grateful if I would get your advices Brian
Hi Brain PS2 have 4 signals VCC,gnd,data and clk Format of data from PS2 is start bit-data bits-parity bit-stop bit Read 'data' line when 'clk' goes low.store and rotate bits to get a data byte. Above mentions how u read data from PS2 now how u interpret received data to useful one,u have to refer documents available from net. Regards Naresh
