The teensy will definitely work (
https://github.com/collin80/TeensyRET) but you might need a couple more dupont cables for CAN high and low
[...]
Ah, here's the Teensy on the wiki:
https://openinverter.org/wiki/Getting_C ... Teensy_3.6 (I know yours is a 3.2, but it still has CAN0.
May need to adjust TeensyRET to not try opening CAN1?)
EDIT - no, CAN1 is enabled by a setting somewhere, looks like there's a config menu accessible over serial, or perhaps through Savvycan itself
I think I am pretty close but getting some errors whilst trying to compile the TeensyRET sketch in Arduino, so I figure I would share as both a cry out for help and also to demonstrate to those who may attempt this and come across something similar
this is the reason why I left SaavyCAN on Teensy for last as this cake has the most layers of complexity
