| May 12, 2017 at 11:33 | comment | added | Jeroen3 | then the last thing I can think of is timing mismatch. Are they both running a stable HSE? | |
| May 12, 2017 at 11:32 | comment | added | bananamana | Sorry, I forgot to mention that I do have a CAN tranceiver on my board. The signals in the picture are the Rx and Tx lines between the micro and the tranceiver. | |
| May 12, 2017 at 11:05 | comment | added | Jeroen3 | You must use a CAN Transceiver, like MCP2551, because CAN uses differential signalling. Or: electronics.stackexchange.com/questions/30564/… | |
| May 12, 2017 at 10:55 | comment | added | bananamana | Yes, I'm using the same lines for both v7 and v8. They are terminated at both ends. | |
| May 12, 2017 at 10:44 | comment | added | Jeroen3 | What do the actual CAN lines look like. Are they 120ohm terminated? | |
| May 12, 2017 at 10:10 | comment | added | bananamana | It looks like I'm getting a "bit dominant error" according the the STM manual. Unfortunately it does not describe what that is and how I might go about resolving it.. | |
| May 12, 2017 at 8:09 | comment | added | bananamana | The can controller is built into the microcontroller (stm32f103z). I'll check if there's a register that reports errors. | |
| May 12, 2017 at 7:30 | comment | added | Jeroen3 | It looks Ok, except for receiving an error frame in V8? Do you have Acknowledge errors or did you develop the CAN controller yourself? | |
