Actually the program I have been using for testing is very simple, it just set output mode and changes pins in a loop. Is it possible to blow up the SX28 just by putting power ON and OFF ? :confused: I am working with the Professional Dev Board.

Usually I remove power without setting the board OFF. ---------- End of Message ---------- You can view the post on-line at: http://forums.parallax.com/forums/default.aspx?f=7&p=1&m=105037#m105054 Need assistance?
