HAL LPTIM function migration

This section provides information about the HAL LPTIM function migration.

HAL LPTIM start counter

HAL1

HAL2 

HAL_LPTIM_Counter_Start(LPTIM_HandleTypeDef *hlptim);

HAL_LPTIM_Start(hal_lptim_handle_t *hlptim);

HAL LPTIM start counter with interrupt

HAL1

HAL2 

HAL_LPTIM_Counter_Start_IT(LPTIM_HandleTypeDef *hlptim);

HAL_LPTIM_Start_IT(hal_lptim_handle_t *hlptim);

HAL LPTIM stop counter

HAL1

HAL2 

HAL_LPTIM_Counter_Stop(LPTIM_HandleTypeDef *hlptim);

HAL_LPTIM_Stop(hal_lptim_handle_t *hlptim);

HAL LPTIM stop with interrupt

HAL1

HAL2 

HAL_LPTIM_Counter_Stop_IT(LPTIM_HandleTypeDef *hlptim);

HAL_LPTIM_Stop_IT(hal_lptim_handle_t *hlptim);

HAL LPTIM read auto-reload value

HAL1

HAL2 

HAL_LPTIM_ReadAutoReload(const LPTIM_HandleTypeDef *hlptim);

HAL_LPTIM_GetPeriod(const hal_lptim_handle_t *hlptim);

HAL LPTIM read captured value

HAL1

HAL2 

HAL_LPTIM_ReadCapturedValue(const LPTIM_HandleTypeDef *hlptim,
                                     uint32_t Channel);

HAL_LPTIM_IC_ReadChannelCapturedValue(const hal_lptim_handle_t *hlptim,
                                               hal_lptim_channel_t channel);

HAL LPTIM read counter value

HAL1

HAL2 

HAL_LPTIM_ReadCounter(const LPTIM_HandleTypeDef *hlptim);

HAL_LPTIM_GetCounter(const hal_lptim_handle_t *hlptim);

HAL LPTIM get state

HAL1

HAL2 

HAL_LPTIM_GetState(const LPTIM_HandleTypeDef *hlptim);

HAL_LPTIM_GetState(const hal_lptim_handle_t *hlptim);

Note

In HAL2, a new API called HAL_LPTIM_GetChannelState(const hal_lptim_handle_t *hlptim, hal_lptim_channel_t channel) is introduced to retrieve the current state of a specified LPTIM channel.
