!! 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:
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
Python module to serve the app. Note: may not be necessary.
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)
Designs
Overdrive / Errors
Normal Drive
Charging
