Sum of quanta, times prescaler, divided into APB clock the CAN is on.

Hello,

The way how to calculate manually CAN baudrate you can find in MCU's reference manual, in chapter related to CAN interface. Please find below the part related to this subject and relationship between it and STM32CubeMX.

Hello Kadir,

Please refer to this thread:

https://community.st.com/0D50X00009XkWfySAF

. Inside it I attached two presentations: for STM32F7 and STM32L4. Each of them shows how to create a simple CAN bus application step by step from scratch. In this thread you can also find an information where to look for example CAN applications in Cube repository. I hope this content willhelp you to make CAN working on your side.

Szymon
