这些是可以调整的。比方： hcrc.Instance = CRC;   hcrc.Init.DefaultPolynomialUse = DEFAULT_POLYNOMIAL_DISABLE;   hcrc.Init.DefaultInitValueUse = DEFAULT_INIT_VALUE_DISABLE;   hcrc.Init.GeneratingPolynomial = 7;   hcrc.Init.CRCLength = CRC_POLYLENGTH_16B;   hcrc.Init.InitValue = 0x06458458;   hcrc.Init.InputDataInversionMode = CRC_INPUTDATA_INVERSION_NONE;   hcrc.Init.OutputDataInversionMode = CRC_OUTPUTDATA_INVERSION_DISABLE;   hcrc.InputDataFormat = CRC_INPUTDATA_FORMAT_HALFWORDS;   if (HAL_CRC_Init(&hcrc) != HAL_OK)   {     Error_Handler();   }
