Re: Pyro Propeller Clock POV

Chris, I was wondering if you could provide clarification on your crystal oscillator. You state it is 40MHz, but the part number at jameco is for a 20MHz so which is it. Also, how did you get the crystal to function without the 20pF shunt capacitors? When I scope a 40MHz crystal with my PIC it only ...
