Hello @Kamil Duljas ,

Could you please share more information ?

I just communicate 2 stm32F7 boards through CAN and I see in examples need to configure 

CAN_FilterTypeDef CAN_FilterInitStructure

but I don't see any settings in CubeMX

Hello @Kamil Duljas , 

You need too add can filters into the code, for example : 

  /*##-2- Configure the CAN Filter ###########################################*/
  sFilterConfig.FilterBank = 0;
  sFilterConfig.FilterMode = CAN_FILTERMODE_IDMASK;
  sFilterConfig.FilterScale = CAN_FILTERSCALE_32BIT;
  sFilterConfig.FilterIdHigh = 0x0000;
  sFilterConfig.FilterIdLow = 0x0000;
  sFilterConfig.FilterMaskIdHigh = 0x0000;
  sFilterConfig.FilterMaskIdLow = 0x0000;
  sFilterConfig.FilterFIFOAssignment = CAN_RX_FIFO0;
  sFilterConfig.FilterActivation = ENABLE;
  sFilterConfig.SlaveStartFilterBank = 14;

I suggest you check the available example in the stm32f7 cubefw : STM32Cube_FW_F7_V1.17.0\Projects\STM32756G_EVAL\Examples\CAN

Hello @Kamil Duljas 

First let me thank you for posting.

I assume this is the exact same request CubeMX feature request: Is it possible to add HAL_... - STMicroelectronics Community  already raised to the development team and tracked by the Tickets 148949 and 149021 and that will be added to CubeMX  as soon as possible.

Thx
