 ===============================================================================
    [..]
    This subsection provides a set of functions allowing to control the ADC.
     (+) hal_adc_get_state() API can be helpful to check in run-time the state of the ADC peripheral.
     (+) hal_adc_get_error() check in run-time Errors occurring during communication.

Function Documentation

◆ hal_adc_get_error()

uint32_t hal_adc_get_error ( adc_handle_t p_adc)

Return the ADC error code.

Parameters
[in]p_adcPointer to an ADC handle which contains the configuration information for the specified ADC module.
Returns
ADC error code in bitmap format

◆ hal_adc_get_state()

hal_adc_state_t hal_adc_get_state ( adc_handle_t p_adc)

Return the ADC handle state.

Parameters
[in]p_adcPointer to an ADC handle which contains the configuration information for the specified ADC module.
Return values
HAL_ADC_STATE_RESETPeripheral not initialized.
HAL_ADC_STATE_READYPeripheral initialized and ready for use.
HAL_ADC_STATE_BUSYAn internal process is ongoing.
HAL_ADC_STATE_ERRORPeripheral in error.

◆ hal_adc_resume_reg()

hal_status_t hal_adc_resume_reg ( adc_handle_t p_adc)

Restore some registers related to ADC configuration after sleep. This function must be used in conjunction with the hal_adc_suspend_reg().

Parameters
[in]p_adcPointer to a ADC handle which contains the configuration information for the specified ADC module.
Return values
HAL_OKOperation is OK.
HAL_ERRORParameter error or operation not supported.
HAL_BUSYDriver is busy.
HAL_TIMEOUTTimeout occurred.

◆ hal_adc_suspend_reg()

hal_status_t hal_adc_suspend_reg ( adc_handle_t p_adc)

Suspend some registers related to ADC configuration before sleep.

Parameters
[in]p_adcPointer to a ADC handle which contains the configuration information for the specified ADC module.
Return values
HAL_OKOperation is OK.
HAL_ERRORParameter error or operation not supported.
HAL_BUSYDriver is busy.
HAL_TIMEOUTTimeout occurred.
