programming for PIC 16F877a

hi
I m using C compiler for programming the 16f877a. I would like send binary data through this PIC by using RS 232 communication which able to transmit data serially. I would to program like i have a push button connected to PIC. When a press the push button, the pic will send certain binary data(8bit).So i hope the members would give suggestion or idea or perhaps some example of programming regarding this topic.

Hi, which compiler are you using? You can either use polling to detect the switch press or use interrupts and have the Transmit routine in there. But examples can only be provided if you tell us which compiler you have got.

i m using CSS C compiler. So can you help me

Hi,I use C18. Use the interrupt directives(P# 125) in the manual, look at the examples on this link to get the RS232 part done and you will be done.
