HAL CRC default init value ¶

HAL1	HAL2
DEFAULT_CRC_INITVALUE	Removed(Use `LL_CRC_DEFAULT_CRC_INITVALUE` instead)

HAL CRC default polynomial value ¶

HAL1	HAL2
DEFAULT_CRC32_POLY	Removed(Use `LL_CRC_DEFAULT_CRC32_POLY` instead)

HAL CRC default polynomial ¶

HAL1	HAL2
#define DEFAULT_POLYNOMIAL_ENABLE #define DEFAULT_POLYNOMIAL_DISABLE	This configuration has been removed as it is no longer optional. To use the default parameters, no additional configuration is necessary. If customization is required, please use the `HAL_CRC_SetConfig()` function.

Related use case: CRC calculation with user configuration

HAL CRC default init value ¶

HAL1	HAL2
#define DEFAULT_INIT_VALUE_ENABLE #define DEFAULT_INIT_VALUE_DISABLE	This configuration has been removed as it is no longer optional. To use the default parameters, no additional configuration is necessary. If customization is required, please use the `HAL_CRC_SetConfig()` function.

Related use case: CRC calculation with user configuration

HAL CRC polynomial sizes ¶

HAL1	HAL2
#define HAL_CRC_LENGTH_32B #define HAL_CRC_LENGTH_16B #define HAL_CRC_LENGTH_8B #define HAL_CRC_LENGTH_7B	Removed because the CRC length is automatically equal to the polynomial size: - HAL_CRC_POLY_SIZE_32B - HAL_CRC_POLY_SIZE_16B - HAL_CRC_POLY_SIZE_8B - HAL_CRC_POLY_SIZE_7B

Related use case: CRC calculation with user configuration

HAL CRC input buffer format ¶

HAL1	HAL2
#define CRC_INPUTDATA_FORMAT_UNDEFINED #define CRC_INPUTDATA_FORMAT_BYTES #define CRC_INPUTDATA_FORMAT_HALFWORDS #define CRC_INPUTDATA_FORMAT_WORDS	Removed; the buffer size and alignment are now internally managed by the accumulate and calculate functions.
