Please can someone explaine to me what pins i should connect to the SX and what options to set in the SX software / compiler. I have read things about doing this but because I am new at it. I am afraid that I might damage my chip so if anyone can help me get into this great hobby thanks for your time. ---------- End of Message ---------- You can view the post on-line at: http://forums.parallax.com/forums/default.aspx?f=7&p=1&m=190114 Need assistance?
