In SX Microcontrollers, SX/B Compiler and SX-Key Tool, Rsadeika wrote: Back in Nov or Dec of last year Guenther had a post describing how to test the SX-key to see if has been damaged. I cannot remember the name of the post, so you may have to do some searching for the post. Have you tried a very simple program to see if you can get that to step through? I know that I have had some programs that were doing exactly what you have described, my SX-key was still good. ---------- End of Message ---------- You can view the post on-line at: http://forums.parallax.com/forums/default.aspx?f=7&p=1&m=132602#m132876 Need assistance?
