I made a thing: https://openinverter.org/wiki/State_of_ ... Teensy_4.0
It's a prototype CAN bus state-of-charge meter based on a Teensy 4.0. It displays a state-of-charge or voltage value according the integer number sent over CAN bus to the configured address(es)
I used a 4-digit 7-segment LED display for a proper 80's vibe.
A touch sensor allows you to toggle the display between SoC and voltage and it includes automatic night time dimming.
I plan to build it into an existing analogue ammeter on my bike project. Hopefully the code is useful for others here.

Re: Simple CAN bus state of charge / battery voltage display
Are you getting battery voltage through can from an openinverter board? Ive been looking to see if battery voltage is available through can . Im using a dual motor board for prius gen 3 inverter.

Re: Simple CAN bus state of charge / battery voltage display
I'm using an Isabellenhütte IVT-S for now, but I'm expecting the pack voltage and/or SOC will eventually come from the BMS (Orion)...
