Re: PIC 18F2431
Everyone:
I found the problem, and it had nothing at all to do with the program. Not even the config bits. The problem was with the sensor itself. The PIC was pulling more current than the sensor could put out, and so the pulse 'highs' were being pulled to almost ground, so the device could not read the pulses as occuring. Throw in an NPN transistor, and the whole thing was working fine. Thanks for all your time, especially Mike Betts.
This post can now languish into obscurity.
