I have a footpedal fitted with three footswitches. I want to wire these
up to a suitable IC to transmit data (different data for each switch)
over an RS-232 serial cable which is connected to a computer (actually
a PDA but that's irrelevant to the solution). I will have software
running on the computer to read incoming data on the RS-232 line to
identify which footswitch has been pressed.
I can handle the software on the computer no probs but don't know how
to build this 'intelligent' footswitch. Please help!
