Q1?
Hey everyone. I downloaded the test app, and it responds with a failure on the VPP line. After poking at the source, and reviewing what it is doing (purely reading back from the VPP_FB line), I have the following question.
For a standard 18F family part, VPP should be up to 12V (according to the troubleshooting).
Anyone have a pointer to a document that details how the charge pump is supposed to work? I can see the pulses on the VPP_PUMP line, but I'm not sure if Q1 is actually doing anything. (Again.. software guy here). Is there any way to test Q1 in place? Or do I need to pull the part from the board?
