Although I ran across something in the manual that showed a 10k across the osc pins so I have tried that as well. When I put in the resonator the center pin goes to GND. It never causes a problem to program having the resonator in, and the Blitz manual says it doesn't cause problems usually. I have tried several different 50's and several different 4's. I always change the FREQ to the frequencey of the resonator, 4m res = FREQ 4m adn 50m Res= 50m. ---------- End of Message ---------- You can view the post on-line at: http://forums.parallax.com/forums/default.aspx?f=7&p=1&m=143298#m143421 Need assistance?
