Hi,
I have 3x PCBs, with 18F46K20 PICs.
There is something not right when they are programmed, as they seem to work for a while, then don't. 1x of them has never worked.
The error seems to me to be a PCB problem, so I checked, continuity, and separation of tracks etc.
I have been testing the 3x programming connections with a digital analyser, and saved the outputs of the tests, for comparison. When compared the data always seems different.
What tests can I do to find out what's going on?
C
