In SX Microcontrollers, SX/B Compiler and SX-Key Tool, Zoot wrote: Both sides look good. Seems like this should work, presuming wiring is perfect and you've got enough power. Make sure you using "program" if you are running the SX from an external resonator or "run" if you are using the SX-Key clock. Personally, I would hook up a wall-wart to your board for power, yank the resonator, and try to get this running properly from the SX-Key. If you can do that, then at least you'll know that subsequent problems are in your resonator and/or resonator hookup. Again, make sure to "run" if you are using the Key as a clock source. ---------- End of Message ---------- You can view the post on-line at: http://forums.parallax.com/forums/default.aspx?f=7&p=1&m=264135#m264253 Need assistance?
