Starting CAN failed! #84

Open mianqi2016 opened 2 years ago

mianqi2016 commented 2 years ago

I used a module with MCP2515 + TJA1050 on Arduino UNO, I tried 2 modules on 2 UNO with sender and receiver example, and I have changed parameters for MCP2515, but it just prompted: Starting CAN failed!

CAN.setSPIFrequency(4E6); CAN.setClockFrequency(8E6); if (!CAN.begin(10E3))

What maybe the reason?

qubolino commented 2 years ago

does it start without changing spi and clock freq?

mianqi2016 commented 2 years ago

No, so I went to change them.

My wiring was here: https://forum.arduino.cc/t/starting-can-failed/944127/4

No.

I found if you select "ACAN" in Arduino IDE "Library Manager", you could meet others CAN libraries, I havn't try them, maybe there is any could run.

I am having the same issue. Did you find a solution?
