I use a CAN BUS gyroscope in my project, I connect it via tja1050 with my MCU(stm32 f103RCT6).I believe that the hardware connection has nothing wrong, and I can see the signals on the BUS using oscilloscope . However, I can't go into the CAN BUS receive interruption, why?images are my code0693W000005BaUdQAK.png0693W000005BaRpQAK.pngI really appreciate your help, thank you!!

Do the error counters go up ?

Check your wiring and the terminating resistance.

I used a tja1050 module like this , do I still need a terminating resistance?
