Is CAN LO CAN_RX or CAN_TX ? #3

Open jphein opened 3 years ago

jphein commented 3 years ago

The PNG pinout is labeled CAN HI and CAN LO. The board is labled CAN_RX and CAN_TX. Which goes to which?

jphein commented 3 years ago

In other words: Does CAN_RX go to Yellow, and CAN_TX go to Green?

I wouldt just try it. It cant demage them, but if you mixed them up it just don't works

I was trying to do this with the blue pill alone.

BastelPichi commented 3 years ago

i tried it to but o have other batterys so i dont now if it worked or if just they use a other comunication. Did you tried it ? Did it work?

jphein commented 3 years ago

It never worked for me. I think you also need a can transceiver: https://github.com/alex3dbros/LGH1ScooterPackPower/issues/5#issue-823619017

Have tried CAN_H and CAN_L on both PA11 and PA12 with just a Bluepill - no dice.

This is with a battery that will successfully unlock if used with Jehu's board.

EDIT: Farted around a bit more with it; it does need a transceiver.
