For instant-gratification you can try the Propeller HAT IO libraries:
You'll need Propeller IDE to start programming your Propeller HAT:
As always, we've made it super-easy for you to get all the software you need with a nifty one-line installer. To run it fire up Terminal which you'll find in Menu -> Accessories -> Terminal on your Raspberry Pi desktop like so:
In the new terminal window type:
curl -sS get.pimoroni.com/propellerhat | bash
This will install a fairly recent version of the Propeller IDE but if you'd like you can head over to www.lamestation.com/propelleride/ and grab the latest version of Propeller IDE for the Raspberry Pi, which may be newer than the one installed by the one-line installer.
It's easier if you grab the right URL, and use the wget command on your Raspberry Pi to download it. For example:
wget https://github.com/parallaxinc/PropellerIDE/releases/download/0.36.7/propelleride-0.36.7-armhf.deb
Once downloaded, you can install it with:
sudo dpkg -i propelleride-0.36.7-armhf.deb
Everything you need to get started with Propeller IDE and your first SPIN program.
Suport software and Python-based uploader tool.
