'Using a crystal'
eter J. (GEA, 068974 )
I'm trying to graduate from using RC timing in my PIC projects so I
spent the last week working on a motor speed control program and circuit
that is based around a 4MHz crystal. I must be missing some fundamental
concept because with everything else the same, the circuit works with RC
but not the crystal.
Is there more to using a crystal than placing it between OSC1 and OSC2
and using two 15pF caps to ground? (incidentally I am using both a 54
and an F84)
many thanks & best regards,
