Just got a USB programmer from Dontronics.

Works very well with MPLAB.

I have noticed a behaviour with my PIC cct and would like to hear your
experiences.

When I program the 16F877 in LVP mode, and hit reset, the PIC stops.

When I programe the 16F877 in HVP mode, and hit reset the PIC resets and
starts again.

It is like the PIC in the first case thinks it is in program mode ?

The MCLR has the usual button to deck and 10 k to VCC.

Not really a problem, just an observation.

Andrew
