Development Environment
AVRSimon was developed on OS X using CrossPack for AVR:
http://www.obdev.at/products/crosspack/download-de.html
Formerly known as AVR MacPack, the package contains the core compiler, debugger, and AVR-specific
tools and integrates seamlessly with Apple’s Xcode.
In-circuit device programming was achieved using an adafruit industries USBtinyISP interface:

If you choose to modify AVRSimon’s firmware, you’ll need to recompile the code and then reprogram it
into the microcontroller. To reprogram, hook up the USBtinyISP to P1 (insert and solder this optional 6-
pin male header onto AVRSimon if you haven’t done so already), locating pin 1 by its square pad on the
backside of the circuit board (as opposed to the other pads on the connector which are circular). Then,
open a Terminal window and go to your /firmware/ directory. Finally, run the make install command,
which launches the avrdude application twice with different parameters - once to load the compiled
binary into Flash memory and once to set the device’s configuration fuses (set in the Makefile):
