Aux display for my 2011 Camaro. Reads off the single wire CANbus, displays various data on a DFRobot 8 digit 7-segment SPI display. Also displays some data on the cluster's navigation DIC text screen and handles steering wheel controls for my Kenwood radio.
Uses a much improved FlexCAN driver, interrupt driven and makes use of multiple mailboxes. Steering wheel controls are MUCH more responsive now.
