I have tried a 10k as shown in the manual across osc 1 and 2 as well. I have tried 2 resonators, both from Parallax. I have tried pulling the Blitz after programming, and leaving it in, no difference. The basic circuit is the resonator to th eosx pins and the center pin on the resonator to GND. There's got to be something I am missing. ---------- End of Message ---------- You can view the post on-line at: http://forums.parallax.com/forums/default.aspx?f=7&p=1&m=143298#m143357 Need assistance?
