ADC - Analog to Digital Converter

Description

Analog to Digital Converter (ADC) Peripheral API.

This module contains functions to control the ADC peripheral of Silicon Labs 32-bit MCUs and SoCs. The ADC is used to convert analog signals into a digital representation.

For ADC architectures with the ADCn->SCANINPUTSEL register, use ADC_ScanSingleEndedInputAdd() to configure single-ended scan inputs or ADC_ScanDifferentialInputAdd() to configure differential scan inputs. ADC_ScanInputClear() is also provided for applications that need to update the input configuration.

When selecting an external reference, the gain and offset calibration must be set explicitly (CAL register). For other references, the calibration is updated with values defined during manufacturing. For ADC architectures with the ADCn->SCANINPUTSEL register, use ADC_ScanSingleEndedInputAdd() to configure single-ended scan inputs or ADC_ScanDifferentialInputAdd() to configure differential scan inputs. ADC_ScanInputClear() is also provided for applications that need to update the input configuration.

◆ ADC_ScanDifferentialInputAdd()

uint32_t ADC_ScanDifferentialInputAdd ( ADC_InitScan_TypeDef * scanInit,
ADC_ScanInputGroup_TypeDef inputGroup,
ADC_PosSel_TypeDef posSel,
ADC_ScanNegInput_TypeDef negInput
)

Initialize the ADC scan differential input configuration.

Set a configuration for the ADC scan conversion with differential inputs. The ADC_InitScan_TypeDef structure updated by this function should be passed to ADC_InitScan() .

Parameters
[in] scanInit Structure to hold the scan and input configuration.
[in] inputGroup ADC scan input group. See section 25.3.4 in the reference manual for more information.
[in] posSel APORT bus pair select. The negative terminal is implicitly selected by the positive terminal.
[in] negInput ADC scan alternative negative input. Set to adcScanNegInputDefault to select a default negative input (implicit from posSel).
Returns
Scan ID of the selected ADC input. See section 25.3.4 in the reference manual for more information. Note that the returned integer represents the bit position in ADCn_SCANMASK set by this function. The accumulated mask is stored in the scanInit->scanInputConfig->scanInputEn.

◆ ADC_InitSingle()

void ADC_InitSingle ( ADC_TypeDef * adc,
const ADC_InitSingle_TypeDef * init
)

Initialize the single ADC sample conversion.

See ADC_Start() for starting a single conversion.

When selecting an external reference, the gain and offset calibration must be set explicitly (CAL register). For other references, the calibration is updated with values defined during manufacturing.

Note
This function will stop any ongoing single conversion.
This function will set the BIASPROG_GPBIASACC bit when selecting the internal temperature sensor and clear the bit otherwise. Any application that depends on the state of the BIASPROG_GPBIASACC bit should modify it after a call to this function.
Parameters
[in] adc A pointer to the ADC peripheral register block.
[in] init A pointer to the ADC initialization structure.

◆ ADC_TimebaseCalc()

uint8_t ADC_TimebaseCalc ( uint32_t hfperFreq )

Calculate a timebase value to get a timebase providing at least 1 us.

Parameters
[in] hfperFreq Frequency in Hz of the reference HFPER/HFPERC clock. Set to 0 to use currently defined HFPER/HFPERC clock setting.

The ADC clock is given by: (HFPERCLK or HFPERCCLK) / (prescale + 1).

Note
The return value is clamped to the maximum prescaler value that the hardware supports.
Parameters
[in] adcFreq ADC frequency wanted. The frequency will automatically be adjusted to a valid range according to the reference manual.
