I think there are about 3 bits which will nudge the frequency. You would need to measure the output though with a frequency counter. It's a lot of hassle versus an external source which would be rated for 100ppm precision for the cheaper ones. I don't know if you looked at all your IR receiver modules, Digikey carries the Sharp line at low cost and high performance. ---------- End of Message ---------- You can view the post on-line at: http://forums.parallax.com/forums/default.aspx?f=7&p=1&m=195677#m195838 Need assistance?
