Hi everyone! This is my first post I hope you guys can help me with my problem that I've been having for the longest time. I am trying to program a stepper motor using a PIC16F877. I have the code running and all. But my problem is that I cannot program it on to the chip.
:cry:
Before I had a EL Cheapo programmer (http://www.myke.com/elcheapo.htm) where I loaded the bootloader then loaded my hex file into the PIC using a software called "PIC Downloader" by Petr Kolomaznik. It was working before but suddenly it stopped. I've been working at this for a week now. But nothing!
When I try to program it, it just goes to 100 percent in a second which doesn't seem right. And when I verify it is tells me that it found another address that it wasn't supposed to find.
So I went to another programmer called the NOPPP, not sure if anyone heard of it before (http://www.covingtoninnovations.com/noppp/nopppcount.shtml). This NOPPP programmer writes the HEX file into the PIC exactly the way it supposed to but then for some reason it doesn't move the stepper motor when I place the chip inside the circuit.
My question is if anyone is familar with the NOPPP, "Can I take a new PIC and just load a HEX file into the PIC via the NOPPP and use it in my circuit assuming that my code is correct.
*What I did to confirm that it loaded it right was, I loaded the HEX into the PIC then read from the PIC and saved the Hex file and compared the two files*
Thanks all.!!!
or can you guys recommend another PIC16F877 programmer that is easy to build and use thanks everyone for all your help. Very very grateful.
