PicoCANGauge

Car is running a Haltech Elite 1500 ECU, CAN protocal

Hardware:

• Raspberry Pi Pico 2 (should work on a RP2040 Pico as well)
• Waveshare 1.28" Round Display Module with touch (GC9A01 display driver)
• Adafruit PiCowBell MCP2515 CANbus module
• 3D printed display housing that fits inside an MX5 NA/NB airvent

Installing dependencies with Circup

Make sure that you have circup installed in your Python environment. Install it with the following command if necessary:

pip3 install circup

With circup installed and your CircuitPython device connected use the following command to install all the dependencies:

circup install gc9a01 toml displayio_dial adafruit_mcp2515

Or the following command to update an existing version:

circup update

TODO:

• Add labels below the gauges to tell which is which
• Change the Tic marks to match the range/scale of different channels being displayed at the moment they will only display 0-100 so I have chosen to set the tick font size to 0 for channels this doesn't make sense for.
• Do an alternate version or mode where one dial occupies the full display
• Add touch, adafruit_cst8xx should work with the waveshare display, have the touch cycle through different sets of gauges/dials.
• Implement a menu that can modify the settings.toml
