Simple CAN bus state of charge / battery voltage display
I made a thing: https://openinverter.org/wiki/State_of_Charge_meter_using_a_Teensy_4.0 IMG_0891 (1).jpeg 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...

Re: The joy of Finite State Machines
Glad the GitHub is useful. I really need to add some more stuff to it...
My plan is to build the CANbus instruments using Teensy 3.2 boards. Not the cheapest solution, but they are tiny, easy to use and have on-board CAN. Space is going to be tight in that little ammeter

Re: The joy of Finite State Machines
The main change to my design is that the "power" and "range" displays will now be CANbus instruments. The VCU will send motor power messages over CANbus to a (modified) analogue rev counter containing a stepper motor and the battery management system will send the state of charge...

Re: Trying to compile GVRET using Arduino DUE
Anyway, it's much better if you can build from source because then it's possible to understand how it works
Clean build should work. I'm keen to understand why it's not working for you so I can get the Wiki instructions right.
What files have you got in libraries/can_common ?

Re: Controlling an analog dash
Yep, last time I made a board it was paper tape, dunked in ferric chloride then hand-drilled. I had no idea that SMT boards were accessible to mere mortals. This changes *everything*

Re: Controlling an analog dash
My mind is blown by JLCPCB.
Literally: I just load those files in, click "SMT assembly", pay around $70 and I get 5x assembled boards in the post a few days later?
Is it really that simple?? That is incredible.

Re: Chevy Volt Battery Questions
The Volt battery is 390V when "full", which is 87% SOC according to the NHTSA fire report (see p.100) http://www.nhtsa.gov/staticfiles/nvs/pd ... eports.pdf
I think GM don't go any lower than 330V in normal use (i.e. for 10kWh of usable capacity)
