Hi, I just posted a question about a related problem in the General Chat lounge, but I also have a question on programming/running a PIC16F627.
I am trying to rule out problems on a Velleman kit board, I am able to program a chip on it and read/verify the data, but on selecting RUN with a switch, the chip fails to function.
Is the oscillator on OSC1 / OSC2 required during the programming phase? I removed the OSC, and was able to program the chip, but I wonder whether the crystal is faulty.
The circuit diagram is available at the following URL:
**broken link removed** Page 10.
Any guidance?
