Hi Folks, I've been playing around with a sample 16F877 and I am having problems with not getting a reliable start up. I'm trying to run it at 4 MHz (using a crystal and two 15 pF caps). The operation of the oscillator seems to be hit or miss (mostly miss). I've played around with different parts (I've tried a ceramic resonator, different values for the capacitors) and still nothing that is reliable. I have not tried an in-line resistor. Has anybody else seen this type of problem and if you did, what did you do to fix it? Thanx, myke
