If it's just the simulator (which doesn't do much except parse statements)...
git clone --recursive https://github.com/monome/teletype.git
./tt # to run the simulator
If you want to build the firmware, you'll need
avr32-gcc & co on your path. The
make in the
src directory. Let me know what OS you're on and I can help you get them set up.
We should probably put the dev instructions in the libavr32 repo and then refer everyone there for instructions on how to get started. (edit: I've started on this, will PR it later on)
