Za Init STM32F407 CAN1

Code:

  /* USER CODE END CAN1_Init 1 */
  hcan1.Instance = CAN1;
  hcan1.Init.Prescaler = 16;
  hcan1.Init.Mode = CAN_MODE_NORMAL;
  hcan1.Init.SyncJumpWidth = CAN_SJW_1TQ;
  hcan1.Init.TimeSeg1 = CAN_BS1_13TQ; //CAN_BS1_1TQ <<<<<<<< 13
  hcan1.Init.TimeSeg2 = CAN_BS2_2TQ; //CAN_BS2_1TQ <<<<<<<< 2
  hcan1.Init.TimeTriggeredMode = DISABLE;
  hcan1.Init.AutoBusOff = DISABLE;
  hcan1.Init.AutoWakeUp = DISABLE;
  hcan1.Init.AutoRetransmission = DISABLE;
  hcan1.Init.ReceiveFifoLocked = DISABLE;
  hcan1.Init.TransmitFifoPriority = DISABLE;
  if (HAL_CAN_Init(&hcan1) != HAL_OK)

Za slanje

Code:

    HAL_CAN_Start(&hcan1);
    HAL_CAN_ActivateNotification(&hcan1, CAN_IT_RX_FIFO0_MSG_PENDING);

    CAN_TxHeaderTypeDef txHeader;
    uint8_t txData[8] = {0x11, 0x22, 0x33, 0x44, 0x55, 0x66, 0x77, 0x88};
    uint32_t txMailbox;

    txHeader.DLC = 8;
    txHeader.IDE = CAN_ID_STD;
    txHeader.RTR = CAN_RTR_DATA;
    txHeader.StdId = 0x123;

    HAL_CAN_AddTxMessage(&hcan1, &txHeader, txData, &txMailbox);
