One wire RS232
PostPosted: Sun Aug 13, 2006 7:02 am     Reply with quote
Hi,

Is it possible to use 1 pin for rx & tx? If so, what's the way to do it?

I tried this, but it doesn't work:
#use rs232(baud=9600, parity=N, bits=8, rcv=pin_b5, xmit=pin_b5)

Oh and it will be half-duplex communication ofcourse.. don't worry about timing, cause I just want one side to respond to a byte sent on the other side..

I do that all the time. Here is my usual RS232 setup line:

Code:
#define TXRser      PIN_B0   /* Serial connection to Smart TXR */
#use rs232(baud=1200, xmit=TXRser, rcv=TXRser, invert)
