Hi again, more beginner problems. When I try to run the make file for the led array test, it doesn't seem to load correctly at all. I'm using a Mac. Terminal just stops at this line;

avrdude -c avr109 -p m168 -b 115200 -P /dev/cu.PL2303-00001004 -U flash:w:ledarray.hex:a

and doesn't do anything else.

Also, I may have somehow fried my chip. Just touched it and it's really hot. Argh.

Once you cool your chip down reboot and rewire. Sometimes it is best to strip ALL of your wiring and start over from scratch.

I get the hung avrdude whenever I am running Screen in Terminal and try to interrupt/stop it. Just closing Terminal apparently does not terminate the process so subsequent tries at compiling hang. To stop Screen use Ctrl-a Ctrl-\ (ha it didn't get me this time).

I cannot remember just getting this error in Terminal from running make but a reboot solves it.

Sometimes just unplugging the USB will free you when you hang up. I have a switch on the yellow wire that I flip every time I run make. The yellow wire has enough voltage (on/from my Mac mini) to hold the MCU in a zombie state and has to be interrupted before doing a subsequent make.
