In any mode of FDCAN, receiver doesnot seem to be working. My project is attached.

Hello @akuma.5​,

Did you try the ready-to-use FDCAN examples provided in STM32CubeG0 package?

The ioc file is under this path: \STM32Cube_FW_G0_V1.6.0\Projects\STM32G0C1E-EV\Examples\FDCAN\

You should check the hardware, the transceivers and bitrate.

used the same provided in package.

But could not get the result.

Also, it seems receiver call back & activate notification IS not working>

pLS hElp.

i Am using Nucleo-G0B1RE Development Board.

Pls Help for FDCAN implementation.

How is the CAN transceiver connected to the STM32G0B1 and what CAN bus are you connecting to? Better question is what node is sending ID 0x321 to your STM32G0B1?

[akuma.51]

I Have 2 nos NUCLEO G0B1RE board that i am using to connect. Clock being used is internal 16MHz.

I have already used \STM32Cube_FW_G0_V1.6.0\Projects\STM32G0C1E-EV\Examples\FDCAN\ example. It is not working . You can check UploAded Project.

You still didn't answer about the CAN transceivers. Draw a simple block diagram on how everything is connected together. The example code is not the problem.

i am using max3051 transceiver to connect both boards.

It helps to see a diagram on how you connected everything together. I've answered a similar question last week so the guy drew up diagram. It turns out he didn't connect everything together correctly. Let's make sure you did it correctly before moving forward with other questions.
