[Ss.61]

I try to create a project based on CAN bus but the CAN option is disable in CUBEMX ide.

*Controller - stm32f042g6u8 

*Cube mx ide version - V 4.24

• i want to know how to create a CAN BUS project using cubemx & without it,
• Examples are suggested for better understanding

You can hover over something that is grayed out to find out why. In this case:

 

So go into SYS to swap pins, then you can enable CAN.

Here is one example for STM32F0 with CAN:

https://github.com/STMicroelectronics/STM32CubeF0/blob/4390ff6bfb693104cf97192f98c3dc9e3a7c296a/Projects/STM32072B_EVAL/Examples/CAN/CAN_Networking/Src/main.c

I don't see any for the STM32F042, but the code should be very similar.
