 Errors while running. I've used the same cables with another board using CAN so shouldn't be an issue. Terminations is ok aswell because other devices can talk to each...

I currently have 3 nodes, 2 of them are talking and all has twisted shielded pairs which are 5-10cm in length and the shield is grounded. It's the only device...

Hmm okey, then peripheral_clock_rate should be 36mhz then? Since STM32F103R8T6 is 72Mhz not 64. The receive did work yesterday, not anymore for some reason.. I saw your previous comment on...

Hmm, that result gave 64 Mhz. In my Platformio.ini file , the board is genericSTM32F103R8. Should i switch out the board part number?

Haha i understand why. We use a custom made PCB with STM32F103R8T6 and It's the first time with the STM32 chip family. So I thought i'd should use the genericSTM32F103R8...

Can't use bluepill or blackpill in platformio.ini file to make serial work. If i use genericSTM32F103R8 with HardwareSerial its fine.  its because  However, if i do use genericSTM32F103R8...

I have replaced the termination resistors with 150 Ohm so that i have two terminations at the ends with a bus resistance at 75 Ohm now. No success in sending...

 This is the setup, the connection between the raspberry pi on the right and the CAN analyze tool on the bottom has no shielded nor twisted pairs. I'm not...

Sadly I don't. I can purchase one however if you think that would help ?

The connection:    Your code says that the initialization was ok. I don't think theres anything wrong with the wiring here..
