Configuring CAN Drivers to the STM32L4R9I-EVAL board

[sonic_solutions]

As I tried to find CAN drivers for " STM32L4R9I-EVAL" but I didn't find any, And I tried configuring CAN example of Stm32L476G-Eval board but it is not working.

Anyone who worked on CAN (Protocol )configuring on STM32L4R9I-EVAL board please Guide me in this

Hello @sonic_solutions and welcome to the ST community,

Attached a preliminary configuration of CAN1 on STM32L4R9I-EVAL board: PB8 and PB9 are used for CAN communication.

But from hardware standpoint, you need to ensure: 

JP12 & JP13: fitted.

JP14 fitted in position 1-2:

Remove R235 and R243:

You need to connect another CAN node to the board that has a 120ohm terminating resistor connected on it.

Hope that helps.

Thank you very much for the solution. However, I’m still unclear about the core point.

My main concern is that I need CAN files such that, when the code is flashed onto the STM32L4R9I-EVAL board, it should behave in the following way: upon receiving a CAN message, the board should either print a response or perform an action in response to that message.

Could you please help me with this
