!! Important: Driver display is different from infotainment !!

Driver display is the screen the driver can see speed, charge, drive state, and other driver-critical information on. The software will be run on a raspberry pi zero and be connected to a small 7” display.

Architecture

The software will be split into three parts:

1. Python module to collect CAN messages, via mcp2515 over SPI or otherwise, and transmit them via websocket to the app.

   • Note: may need to ping center console to request drive state upon startup to ensure it starts synced up

2. Python module to serve the app. Note: may not be necessary.

3. A native flutter Linux app that displays all relevant information in a user friendly way.

Requirements

• Upon being powered, the RPI should load the python script and app (in full screen) automatically, with no user input

• The app must display:

  • Speed - speedometer

  • SOC

    • Range

    • Percent

    • Time to full charge (When Charging)

  • Turn Indicators

  • Cruze Control Status

  • Warning Symbols

  • Drive Mode (PNRD)
