Hi all,

I finnaly got my JDM programmer I bought off ebay. It was listed as

"Microchip PIC JDM Programmer" for about $13.00 USD.

Got it and installed it per directions... even installed included winpic800. Didnt work AT ALL.

So I tried IC-PROG... at first it didnt work, but then it did. Worked quite well for some time then just quit again.

Is there something Im missing here or do I just have a bad programmer (or possibly bad com port).?


My IC-PROG config is:

Programmer Type: JDM
Ports: COM1
Interface: Direct I/O
I/O Delay: 20
Comunication: (All boxes are unchecked.)


It particularly seems to have a hard time with more complicated programs. I can flash the basic "Blink" progam and it works fine. The load a more complicated program, using same fuse settings and everything and get verify errors and it reads back like its a blank chip
