ClassicCAN is an open-source display interface that is compatible with the OBD II protocol and fits inside a classic Smiths Instruments 2″ gauge.
I had the idea for this project when I added CAN support to my Juice Box ECU. I wanted to retain some of the original gauges in my Triumph Spitfire but also wanted to add something which would make full use of all the available sensor data the ECU was collecting. ClassicCAN displays this data in a retro style and utilises an original Smiths 2″ gauge enclosure as a capacitive touch interface to cycle through displays. See the wiki for more details.
ClassicCAN features:
- Low profile components
- 240 x 240 circular OLED LCD
- Teensy 4.0 microcontroller support
- Permanent 12V supply for RTC/timekeeping
- CAN interface supporting the OBD II standard
- Capacitive touch navigation
- Bluetooth configuration and data streaming
