I touched the SX and it was burning hot. After pulling the power, I took a look and discovered that one of the leads (Osc1) of my four pin header had worked loose and almost slid completely out of the board. This meant that I only had power and Osc2 connected properly. I'm not sure why this made chip get super hot, but perhaps you should verify that you have a rock solid connection between the SxKey and the chip on all four pins. A bit of a long shot, but you never know. [/quote] Interresting! I've had this happen in the past. Although, I didn't determine what the cause was.

I wonder if this is your probelm also? -Dan ---------- End of Message ---------- You can view the post on-line at: http://forums.parallax.com/forums/default.aspx?f=7&p=1&m=83868#m83890 Need assistance?
