Hi all

I tried to program my 12f675 and it fails to program the chip it appears to erase the device sucessfully. I have copied the programing report below. Any help would be greatly apreciated.

Regards

Christian O'Callaghan

Hello,

Have you tried sending the hex file with the PICKit 3 software to see if it programs that way?

Hi David

I did open the asm file in mplab and program the chip and it did say that it programmed the chip sucessfullly but the hardware did nothing like it was still blank. So im not sure if that is what you mean.

Cheers

Christian

Hello Christian,

Have you added your own configuration data to the project either using the configuration tool in Flowcode or if you are using MPLAB then by embedding the config words into the source code or by using the configuration settings manager. These config settings will need to match your hardware to allow the device to be able to run.

Strange that programming directly from Flowcode is failing, maybe one of the contacts is slightly loose, I get this sometimes if i'm programming without actually soldering the ICSP header to my PCB. Holding the PICkit onto the PCB whilst programming normally works.

If this fails then what about if you use the Flowcode generated hex file with the stand alone PICkit 3 programming software? Is this any better?
