HAL_StatusTypeDef HAL_OPAMP_DeInit

(

OPAMP_HandleTypeDef *

hopamp

)

DeInitialize the OPAMP peripheral.

Note:

Deinitialization can be performed if the OPAMP configuration is locked. (the lock is SW in L4)

Parameters:

hopamp

OPAMP handle

Return values:

HAL

status

HAL_StatusTypeDef HAL_OPAMP_Init

(

OPAMP_HandleTypeDef *

hopamp

)

Initializes the OPAMP according to the specified parameters in the OPAMP_InitTypeDef and initialize the associated handle.

Note:

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

Parameters:

hopamp

OPAMP handle

Return values:

HAL
