Both BS2 and SX/B programs are almost identical but the voltages are correct ~5v coming out of the WR and CS control lines of the BS2 circuit and incorrect at 3v and 2.2v (not 5v) coming out of the same control lines on the SX-28 circuit. There is something differently happening in the SX-28 that needs to be explained. I don't have a scope just a multimeter. ---------- End of Message ---------- You can view the post on-line at: http://forums.parallax.com/forums/default.aspx?f=7&p=1&m=150716#m150866 Need assistance?
