生成STM32h743的Can初始化函数

以下是一个简单的STM32h743的CAN初始化函数：

void CAN_Init(void)
{
    CAN_HandleTypeDef hcan;
    hcan.Instance = CAN1;
    hcan.Init.Prescaler = 5;
    hcan.Init.Mode = CAN_MODE_NORMAL;
    hcan.Init.SyncJumpWidth = CAN_SJW_1TQ;
    hcan.Init.TimeSeg1 = CAN_BS1_12TQ;
    hcan.Init.TimeSeg2 = CAN_BS2_3TQ;
    hcan.Init.TimeTriggeredMode = DISABLE;
    hcan.Init.AutoBusOff = ENABLE;
    hcan.Init.AutoWakeUp = DISABLE;
    hcan.Init.AutoRetransmission = ENABLE;
    hcan.Init.ReceiveFifoLocked = DISABLE;
    hcan.Init.TransmitFifoPriority = DISABLE;
    if (HAL_CAN_Init(&hcan) != HAL_OK)
    {
        Error_Handler();
    }
}

该函数使用了HAL库来初始化CAN，参数可以根据需要进行修改。需要注意的是，需要在main函数中调用HAL_CAN_MspInit函数来初始化CAN的GPIO和时钟。
