Have you ever wanted to hack your CAN (in-vehicle network)? Well, now you can -- no pun intended :P -- and there are plenty of resources out there to help you. For starters, this Hackaday post provides an overview of the hardware available to you for "CAN hacking," mentioning, among other tools, that you can use the chipKIT Max32 as your development platform!
What you might not know is that Ford Motor Company put together a combination of open-source hardware and software that function as an API for your car's internal network, calling it the OpenXC platform. Worth noting is the inclusion of the chipKIT Max32 in their list of officially supported embedded platforms. The OpenXC chipKIT Vehicle Interface, which makes use of the chipKIT Max32, also incorporates a chipKIT Network Shield to send and receive OpenXC messages. With that said, why reinvent the wheel, when OpenXC provides instructions to DIY, and you can download the firmware from Github!
Now that you know how to hack your CAN, what are you waiting for?!? ;) This calls for endless customization of your vehicle interface! Go forth :)
