Presentation: Tweet"Is It A Car? Is It A Computer? No, It's a Raspberry Pi Java Carputer"

Since 2001 all petrol engined cars sold in Europe are required to be fitted with a European On Board Diagnostics (EOBD) interface. Low cost connections to this provide Wi-Fi access to raw car system data. The Raspberry Pi provides a low cost ARM processor based embedded system for multiple uses. This session will look at how Embedded Java and a Raspberry Pi has been used to communicate with the diagnostic and management systems of an Audi S3 and process the data. With the addition of a touch screen we will show how JavaFX has been used to provide an in-car informatics system for less than $200.

Adding an accelerometer to the hardware configuration allows us to measure the forces affecting the car. Exciting data like G-forces, lateral loads, power output and acceleration times can all be added to the display. By accessing CAN bus data it is even possible to repurpose things like steering wheel buttons to provide hands-free control of the interface.

Videos of the system in action will be shown.
