HAL_StatusTypeDef HAL_COMP_DeInit ( COMP_HandleTypeDef * hcomp )

DeInitialize the COMP peripheral.

Note:: Deinitialization cannot be performed if the COMP configuration is locked. To unlock the configuration, perform a system reset.

Parameters:

hcomp COMP handle

Return values:

HAL status

HAL_StatusTypeDef HAL_COMP_Init ( COMP_HandleTypeDef * hcomp )

Initialize the COMP according to the specified parameters in the COMP_InitTypeDef and initialize the associated handle.

Note:: If the selected comparator is locked, initialization can't be performed. To unlock the configuration, perform a system reset.

Parameters:

hcomp COMP handle

Return values:

HAL status
