pic16f877a serial communication
PostPosted: Tue Feb 28, 2012 8:52 am     Reply with quote

Hey ppl,
I'm working on a project in which I've to send a number from one pic16f877a to another one of the same kind, so that the data could be processed there. No matter what I do, its not working :( ... The data is sent, but is not received correctly.
Could somebody please help me with at least the smallest example of pic to pic serial communication that works perfectly. I tried googling, but I couldn't find anything.

I'm kinda desperate here. Please do help.

Thanks.

OK, look at the top of the .lst file in your compiler directory and give us your
compiler version ( 3.xxx or 4.xxx) and then show us what code you have so far.

Have you even looked at the examples CCS kindly supplies in the EXAMPLES folder ?? What about opening the HELP files and looking in the FAQ section where they show and tell how to do serial communications?
It's the same FAQ they had back in 1999, the example worked then for me. it has to work for you today!!

Also HOW do you know it's the receiving PICs problem? You haven't shown us either program..... AND what hardware are you using ???

Another key piece of information missing is the baud rate you are trying to run at and are you using the internal uart or bit-banging ?
