I'm trying to program some 16F1829 chips using my GQ-4X.
I'm told I need an adapter PIC Adapter+, yet this is showing in your store as a legacy product. Do I need this adapter? If not, how can I modify the Devices.txt file to convince the GQ-4X to program the device? |

I've got this working. [Sort of...]
I edited the devices.txt file such that it tells the GQ-4X that a 16F1829 is a 14 pin device, I then place the chip into a 14 pin socket and place it into the programmer socket so that it sits in the position that the (similar device) 16F1825 would sit. This seems to work well.
I have also made a lead to go from the ICSP socket to a 20 pin socket and modified the devices.txt file to enable ICSP programming for this device.
I should add that I had to modify the device ID to 2927E4 and the code size to 8192 as these were incorrect.

Good work.
For the 14pin PIC chips, you can just put it on the GQ-4X programmer ZIF socket. It does not need the adapter. |

| I should add that I have only recently found that the GQ-4X wouldn't program a hex file that was filled with more than 50% (4095 bytes) of program size. I spent some time scratching my head thinking it was my program that was the problem but it was the device file for the 16F1829. This was listed as having a pgmmem size of 0x0 to 0xfff. I have changed this to 0x0 to 0x1fff (0 to 8191). This now seems to 'fix' the problem I was having. |

Thank you.
can you upload the device file you modified? |
