In SX Microcontrollers, SX/B Compiler and SX-Key Tool, Chong wrote: I frequently program SX chips in the field with my laptop. Unfortunately it doesn't have a serial port so I use a Baoyu manufactured USB-Serial adaptor (oriental no name?). I regularly have connection problems which can be overcome by either hitting the "program" button again or unplugging and replugging the USB connection. I have to confess that I also modfied my SX-Key a little. I soldered a 2" wire header to replace the rigid connection. I've checked my connections and I'm sure they're good. Could I have caused an issue with an oscillator or something? ---------- End of Message ---------- You can view the post on-line at: http://forums.parallax.com/forums/default.aspx?f=7&p=1&m=111905 Need assistance?
