how to change rs232 baud_rate on the fly
PostPosted: Sun Oct 15, 2006 8:50 pm     Reply with quote
Hi,
Can I change speeds on the fly??

Eg, I want to run at 4800bps for a while then switch to 9600bps later.


Currently on PIC16F877A, I use:
#pragma use rs232(baud=9600,parity=N,xmit=PIN_C6,rcv=PIN_C7,bits=8)


Thanks for any reply.
(This PCM compiler ain't half bad!)

Download the CCS manual. Go to the section on "Built in Functions".
Each basic module in the PIC has a list of functions that are used with it.
In the list for RS-232, what function looks like it will do what you want ?
