CAN bus state-of-charge display using Teensy 4.0 board

This is a CAN bus state-of-charge meter based on a Teensy 4.0. Teensy's aren't the cheapest boards (an STM32 is a tenth of the price), but they are tiny, have on-board CAN and are very easy to develop for. Instructions here: https://openinverter.org/wiki/State_of_Charge_meter_using_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) SoC values between 0 and 1000 will be displayed as " 0.0" to "100 ". The display flashes " 0.0" when it reaches zero. Anything else (or no data) will be displayed as "----" Voltage values between 1 and 999 will be displayed as " 1V" to "999V ". Anything else (or no data) will be displayed as "---V" A touch sensor allows you to toggle the display between SoC and voltage. It includes automatic night time dimming.
