If this is the same low-power circuit you are talking about in other threads, then I would recommend a 4MHz resonator. If you can be by with the internal 4MHz that's great. But I wouldn't recommend it. Bean. ---------- End of Message ---------- You can view the post on-line at: http://forums.parallax.com/forums/default.aspx?f=7&p=1&m=143298#m143370 Need assistance?
