I am trying to program the 12F series with a MElabs U2 programmer. These are new parts, 12F635s and 12F683s.
First of all, the programmer tells me that the devices have the wrong IDs. Next, when read, I get all 0x00s. I tested the programmer with the 16Fs and it works fine.
The 12s were not previously programmed, and I was careful to set config to RESET the MCLR pin. There is nothing else attached to the chips. I downloaded the latest Meprog software and firmware, but still no go.
This has got me stumped, but I am sure there is some logical explanation...
Any ideas?
Thanks,
Ron
