Time to test if your brand new LED cube actually works!
We have prepared a simple test program to check if all the LEDs work and if they are wired correctly.
You can download the firmware test.hex in this step, or download the source code and compile it yourself.
As in the previous step, we use avrdude for programming:
avrdude -c usbtiny -p m32 -B 1 -U flash:w:test.hex
-c usbtiny specifies that we are using the USBtinyISP from Ladyada -p m32 specifies that the device is an ATmega32 -B 1 tells avrdude to work at a higher than default speed. -U flash:w:test.hex specifies that we are working on flash memory, in write mode, with the file test.hex.
