HAL MDF state and error functions migration ¶

This section provides information about the HAL MDF state and error functions migration.

Note

In HAL1, a single driver handles both MDF and ADF peripherals.
In HAL2, the HAL MDF driver has been split into two separate drivers HAL MDF and HAL ADF. For more details, see : MDF specific concept.

HAL MDF get state ¶

HAL1	HAL2
HAL_MDF_GetState()	HAL_MDF_GetState(const hal_mdf_handle_t hmdf) HAL_ADF_GetState(const hal_adf_handle_t hadf)

Note

For MDF, new API has been provided to get the specified serial interface, short-circuit detector, digital filter and out-of-limit detector state :

            HAL_MDF_SITF_GetState(const hal_mdf_handle_t *hmdf,
                      hal_mdf_block_index_t serial_interface_index)
HAL_MDF_SCD_GetState(const hal_mdf_handle_t *hmdf,
                     hal_mdf_block_index_t short_circuit_detector_index)
HAL_MDF_DFLT_GetState(const hal_mdf_handle_t *hmdf,
                      hal_mdf_block_index_t digital_filter_index)
HAL_MDF_OLD_GetState(const hal_mdf_handle_t *hmdf,
                     hal_mdf_block_index_t out_of_limit_detector_index)

           

For ADF, new API has been provided to get the specified serial interface, digital filter, and sound activity detector state :

            HAL_ADF_SITF_GetState(const hal_adf_handle_t *hadf,
                      hal_adf_block_index_t serial_interface_index)
HAL_ADF_DFLT_GetState(const hal_adf_handle_t *hadf,
                      hal_adf_block_index_t digital_filter_index)
HAL_ADF_SAD_GetState(const hal_adf_handle_t *hadf,
                     hal_adf_block_index_t sound_activity_detector_index)

HAL MDF get error code ¶

HAL1	HAL2
HAL_MDF_GetError()	HAL_MDF_GetLastErrorCodes(const hal_mdf_handle_t hmdf, hal_mdf_block_index_t block_index) HAL_ADF_GetLastErrorCodes(const hal_adf_handle_t hadf, hal_adf_block_index_t block_index)
