HAL_TSC_IOConfig()

HAL_StatusTypeDef HAL_TSC_IOConfig	(	TSC_HandleTypeDef *	htsc,
		TSC_IOConfigTypeDef *	config
	)

Configure TSC IOs.

Parameters

htsc	Pointer to a TSC_HandleTypeDef structure that contains the configuration information for the specified TSC.
config	Pointer to the configuration structure.

Return values

  /* Process locked */

  /* Stop acquisition */
  __HAL_TSC_STOP_ACQ(htsc);

  /* Disable Schmitt trigger hysteresis on all used TSC IOs */
  htsc->Instance->IOHCR = (~(config->ChannelIOs | config->ShieldIOs | config->SamplingIOs));

  /* Set channel and shield IOs */

  /* Set sampling IOs */
  htsc->Instance->IOSCR = config->SamplingIOs;

  /* Set groups to be acquired */
  htsc->Instance->IOGCSR = TSC_extract_groups(config->ChannelIOs);

  /* Process unlocked */
  __HAL_UNLOCK(htsc);

  /* Return function status */
  return HAL_OK;
}

HAL_TSC_IODischarge()

HAL_StatusTypeDef HAL_TSC_IODischarge	(	TSC_HandleTypeDef *	htsc,
		FunctionalState	choice
	)

Discharge TSC IOs.

Parameters

htsc	Pointer to a TSC_HandleTypeDef structure that contains the configuration information for the specified TSC.
choice	This parameter can be set to ENABLE or DISABLE.
