This example extends the MaTouch_SimpleCan example by adding OBD2 PID polling. Code is written to support 2 display sizes, the 2.1" and the 1.28" MaTouch round tft displays. This example is provided as-is. There are no guarantees this will work for your vehicle although it was tested on 2 different makes as well as a generic DIY OBD2 ECU emulator.
