evnow said:Yes - essentially the LED is behaving as if the baud rates are not synced (like you described earlier - with random charatcers showing up after a while). I'll check today whether avr studio 4 lets me run the code in debug mode.garygid said:Just 2 wires, to Gnd and +5v, should light up "0000"
on the SparkFun "serial" LED 7-segment Display.
Are you getting that?
It sounds like you might be having a problem w/ fuse settings ... my baud rates were all messed up when CKDIV8 was set in mine. If you can run avrdude
avrdude -c usbtiny -p at90can128 -U lfuse:r:lfuse.txt:h
(substitute your AVR programmer's name where i have usbtiny) it will dump your low fuse into lfuse.txt. Tell me what's in lfuse.txt and I'll let you know if your low fuse is set correctly.
