    PIC16F877a to SIM900D sms module mikro C programs (sample programs)

    hello fellow engineers.. we are working with our thesis project.

    we use pic16f877a to interface with the sim900D gsm/sms module..

    we are having problems (program) on testing the module if it communicates with the PIC and could really send message..we have tried inserting a sim to the module and call the number on the sim.tapping a speaker in the spkr port of the module with gnd and shorting the micP and micN, the call was answered and able to listen with the call..so we suppose its ok with calls.

    our problem is we need a program ( AT commands )for the pic16f877a to test the module if it could send message.. if u have sample programs pls do help us... thanks friends..

    i understand that we are going to connect the pic's tx to the rx of the module and pic's rx to the tx of the module...
