I am trying to make a Xbox360 rapid fire controller.
I need to program my pic chips with the NEWRF.HEX file found at this link
www.mediafire.com/download.php?ywzxj3jnnzo" target="_blank">hXXp://www.mediafire.com/download.php?ywzxj3jnnzo
I have tried a few other hex files too and the chip never programs.
Here are the exact steps I am taking.
I open my GQ USB Programmer v3.03 software and select the correct device. Dips are set as shown and chip is positioned as shown.
So I check ID and it shows a 12f683 Rev 3 is in programmer.
I erase it and blank check it - fine.
So I open my hex and write it and it fails to verify.
Here is my log
ID check OK
Erasing...
Elapsed time: 0.95 seconds.
Erase completed.
ID check OK
Time:18:23:49
Writing...
Elapsed time: 47.90 seconds.
Time:18:24:37
Device write completedOK
ID check OK
Verifying...Code Memory
VerifyFailed, Address=0x000000, Device=0x00, Buffer=0x28
VerifyFailed
Elapsed time: 7.47 seconds.
When I read back the chip it appears to still be completely blank.
I know my program works. I use it for SST chips all the time.
Any idea what I might be doing wrong.
Please help!!
Thanks |

I got it, There was something wrong with the USB port i was using, For some reason it would not write the chip properly in that usb, I moved to another USB reinstalled drivers and it programed without a hitch |

Not sure why, can you try on different chip?
I tested my GQ-2X and works fine on PIC12F683.

I tried -2 speed. This time the code memory had changed to all 0000 0000 0000 ....
So i erased it and i am back at 3FFF 3FFF 3FFF ...
I also tried another chip and got same results. |

Read the chip after erase, see if its data all 3FFF.
Yes, all code memory is 3FFF after erase. Blank check also passes
Then after i try to write code and read it back it is still blank. All 3FFF
