From James Davidheiser > Question for the electronics savvy amongst you... > > I am building a circuit to interface a PIC16C71 to a serial port. How much serial port signalling do you need to do? If it's single-directional, you don't need a max232, you can just use a resistor and transistor to tie the tx line to either the idle rx line or to the high rts line. I have a serial keypad that does this already, see http://rightsock.com/~kjw/Wearables/SerialKeypad/ Bi Directional probably won't work. I'm also not sure how much power a max232 would draw. I'd suspect it's too much for a serial port, but that's just my guess. - Kevin -- Subscription/unsubscription/info requests: send e-mail with subject of "subscribe", "unsubscribe", or "info" toWear-Hard Mailing List Archive (searchable): http://wearables.blu.org please, Please, *PLEASE* don't subscribe through a forward/false domain
