Simple CAN bus state of charge / battery voltage display

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.
