STM32F4 Discovery to ODrive Communication using CAN interface

1

Hi,

I also started building communication between an STM32F4 and ODrive using CAN interface. However, I don’t see any response for my CAN message for velocity control at ODrive.

Can someone please help me with this matter ?

Below image is my simple code development for CAN Tx message; The CAN message is set to send with the button input interrupt.

Thank you.

I have not used the speed mode, but I have used the position trajectory mode. This is my code based on STM32F4. I hope it could give you some help.

Thanks a for your kind response @Kang_Wang

I even tried position control, more similar to your attached code. Still its not working. May I know what CAN transceiver you are using with STM32F4 discovery board and just to double check, how you define your ID and CMD in your code.

Thanks again.
