Raspberry Pi Low Power OpenXC Display
- Model A or B Raspberry Pi
- Adafruit 16x2 GPIO LCD Display Kit - http://www.adafruit.com/products/1110
- SD Card
- USB Serial or Connection to ChipKit Max32 via USB connection (Make sure not to have both plugged in at the same time or you will overvolt the board!)
In place of this, if you wanted to put the Can Translator somewhere out of view:
- Optional - Compatible Bluetooth Dongle
- Optional - 802.11g/n adapter
Once you have these you can assemble based on instructions for the display, and if you have the interior color LEDs you can even match the Adafruit LCD to match your cars interior.
In vehicles with My Ford Touch the Audio and RCA out also work but are unavailable when the vehicle is in motion. I use this hack to monitor my car's CAN bus with minimal equipment. Could also work as a Rally or Time computer if anyone has a car without the MFT, and normal "Sync" instead. (Apps could be written around this etc.)
A few Python Sources are included in the demo, I will work on getting a hack onto this github asap with what I've been able to do so far.
You could use this to sync with a web api for fuel efficiency, tracking, gps data, etc.
One additional thing that I have not tried so far:
Adding a Temperature and Tachometer / GPS coordinates gauge using the following:
There are some instructions and a few things to get this working, but I think it could be pretty useful when done. There is also a "paper" display that uses low power and could be handy for keeping Battery Voltage statistics or outputting JSON data to Graphite. One of these would likely be better for a hybrid vehicle, for tracking overall MPG and fuel consumption in a brief small window.
A paper display could also have the added benefit of displaying data after the vehicle is parked, and engine off without using much battery power for the display, this would also be great for an odometer.
