Hi ,I am new to STM32 Motor control.I want to control BLDC Motor via B-G431B-ESC1.Also want to use CAN communication.

I used the example from Motor control work bench(ElectronicspeedControl),configured CAN in CubeMX and imported generated code in STMCubeIDE.Now I don't know what should be next step?

Hello @Tejashree​ 

The communication protocol over CAN is not supported yet.

So for the time being, you can use only the UART.

Hi Cedric,The datesheet says it support CAN? I am using B-g431B-ESC1 discovery kit.Also 120ohm resistor on board(r26).Do we have to pull CAN_TERM pin high to start the CAN cOMMINUCATION ?

[cedric H]

Yes, the board support the CAN bus. But the software part is missing.

So, the functions from HAL driver ,example below won't work if implemented?

if (HAL_FDCAN_GetRxMessage(&hfdcan1, FDCAN_RX_FIFO0, &RxHeader, RxData) == HAL_OK)

or can there be any other alternative to implement CAN ?
