How to start program for USART in PIC16877A (using C: initializing *sample program)

Hi friends..i really need help.

we are working with our thesis project and deals with ADC, pic16877a, and a sim900D gsm module

please give me ideas or sample program for this:

pic16877a will do ADC (accept analog voltage) and then the data will be transmitted to the computer (the computer is connected with a mobile phone, we are using the hyperterminal) through pic16's usart port then the usart port is connected to a gsm module sim900D.

how to program for example if we send 5 ( read in ADC as 5 volts) from the pic to the computer..

please..we badly need it.

anyways. we are using MPLab IDE in programming for C language.

It all depends on the C compiler you use. There are mcc18, hitech c and also ccs c and all the functions in the precompiled library is different

MikroC from MikroElektronika - Development tools, Compilers, Books has many samples for UART projects.
