The setup: 2X MCP2515 chips with ATA6561 transiever
https://seengreat.com/wiki/82/dual-ch-can-hat
on a Raspberry Pi 5Trying to connect to a 2013 Ford Fusion through the radio node. The Pi is to replace radio completely.
The CAN HS3 (come factory connected to the radio) twisted pair read 60 OHM across them and both are a fluctuating 2.5V with ground.
When I take the readings on the PI I get the same voltage fluctuation and each of the chips read 120 OHM if their respective termination switch is engaged.
I compiled SavvyCAN for the PI and I am ready to have some fun...
Unfortunately It is radio silence... as in when i initiate the CAN drivers on the PI, the dash goes down! When I say down, it wasn't even recording mileage!!
I've attached some command line stuff, but i was just following some things i had found online, HELP!!
