In SX Microcontrollers, SX/B Compiler and SX-Key Tool, robotworkshop wrote: Do you have any other SX processors (SX28, SX48, etc) or one of the SX28 or SX48 protoboards around? If so it might help to see if you can download one of the example programs in the SX/B help file to see if you can debug one of the other chips. At least that may show if Debug is broken for all chips or an issue specifically related to your board with the SX52. Is there a picture of your board that you can post? What about a schematic? You mention a 10K resistor but there isn't anything stating how it is connected. Is that just a pull up line on the reset? ---------- End of Message ---------- You can view the post on-line at: http://forums.parallax.com/forums/default.aspx?f=7&p=1&m=432894#m432903 Need assistance?
