interfacing PIC16F87x via a serial port using rs232 - Electronic Circuits Projects Diagrams Free

faomari · 29th July 2006, 04:33 AM

Hi, Im in my final stages of my project, unfourtantly this stage requires hardware and software and im desperetly running out of time, all i wana i want to do for now is interface my PIC to the PC via an rs232, i got everything setup correctly. Iv done a bit of software before, but quite hopeless when it comes to hardware. Does anyone have any good website or code that explain how to do this interfacing. Im using MPlab and im looking for code written in HI Tech C. My Serial port has transmission ground, and recieving pins.

Thanks

goto winpicprog.uk and look for rs232 h/w and s/w

thanks for this i read the tutorial for the RS232, and it was very helpful. But all programs seem to be in assembly. do uKnow of any examples for C coding?

Your C compiler should give examples?, can't help you with C, never use it!.

Have a look at HiTechC or CCS

Not sure what version of MPlab you're using, but the configuration panel used to let you set it, to output (from an RS232) to the PC (XP) via the Hypertext terminal (Start/Programs/Accesories/Communications) Using COM1 or COM 2. Would seem a lot of work to write all the handshaking protocols, etc, yourself.
