Hey there, bought the enhanced JDM programmer and I am trying to program a PIC 12F629 microchip but I can't seem to get it to read or write with the programs. Is something wrong with the programmer? I put it in the right slot, the jumpers are on 2-3 & 2-3 and the program is set up correctly. Tried changing the IO delay but that didn't help.
Please help. |

| That program reads the chip fine, but has problems programming. When I program a hex to the chip and read the chip again it isn't the hex I programmed. |

It seems some thing wrong with the setting, not the hardware.
Because the reading and programming are using same hardware circuit, only software commands are different.
Check your config bit see if the code porotection been turned on.
How do you know the reading is correct? |

Actually I am not 100% positive it is reading correct, I am assuming so cause it reads the ocsillator value from the chips.
where do I check the config bit? |

If you are using IC-Prog1.05D, then the right side of windows make sure the CP check box(Code Protection) is not selected.
I'll suggest you to use "winpicpgm_0.9.9.5.exe", then let software to detect the chip see if it works.
Also, where did you put the chip in the ZIF? Have you any other PIC chips? |

I am using winpicpgm now and it detects the correct chip. But after I program all I see are FFFF in all the spots except the last one which has the oscillator value.
I put the chip on the 7th slot (pin 4&5 on the microchip sits in the 7th spot) counting from the serial port. That's the only spot that detects the chip so I am pretty sure that's right.
Only winpicpgm detects the chip, other programs don't. |

If the software can detect the chip, then the only problem could be software or your setting. Because the chip ID only can be read out when the chip in the programming mode.
Do you have another 12F629 for trying?
What exact error message you got when you programming in winpicpgm software?

| Got my 12F629, tested on IC-prog1.05D and it works. |

| I too have purchased the enhanced JDM programmer from yourselves and cant program 12F629's. I get a "VERIFY FAILED AT ADDRESS 0000H" error. I have made sure CP is OFF. I only have access to a dell desktop so maybe its not getting enough voltage. I will try it in work tomorrow on a proper pc and see if i can program it. I was able to program once, just the OSCAL value and the rest zeros, but that may have just been an erase. |

| OK i tried again after reading a howto by ZLM in another post and used icprog 1.05D and changed the oscillator value to RC CLKOUT and it worked YAY! |
