Hey, I was wondering if you would grace me with a few more insights.

Right now I have:

DEFINE ADC_CLOCK 4 ' i know 3 means internal RC, but i want to use the external resonator, is that 4?

DEFINE OSC 20 ' i know 20 means 20mhz, but does that also work for resonators as well as oscillators?

DEFINE SAMPLEUS 50 'i eventually want to sample in the megahertz range if possible,

I'm also going to eventually put in a trigger to start the A/D process and end it after a certain number of samples. Well, off I go into the pic basic manual. Thanks again for the help.
