Thanks for sending me the new cable and chip, Humberto! Unfortunately, I'm still getting an error.

After trying to compile the code using the make command, I get this error:

make -C ../libnerdkits
make[1]: Nothing to be done for `all'.
avr-gcc -g -Os -Wall -mmcu=atmega168  -Wl,-u,vfprintf -lprintf_flt -Wl,-u,vfscanf -lscanf_flt -lm -o initialload.o initialload.c ../libnerdkits/delay.o ../libnerdkits/lcd.o ../libnerdkits/uart.o
avr-objcopy -j .text -O ihex initialload.o initialload.hex
avrdude -c avr109 -p m168 -b 115200 -P /dev/cu.usbserial -U flash:w:initialload.hex:a

Connecting to programmer: .avrdude: butterfly_recv(): programmer is not responding
make: *** [initialload-upload] Error 1

I'm using the new cable, the new chip, and my other Mac running OS X Lion. The device is still listed as /dev/cu.usbserial

Also, I'm left with an initialload.hex and an initialload.o file in the initialload directory. Should I delete these files before trying the make process again?

Nevermind, I flipped the switch and it works now! The programming switch was in run mode rather than programming mode (duh)!

Happens to the best of us, or at least it at least once.
