Detailed 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.

Function Documentation

uint32_t ADC_DataIdScanGet ( ADC_TypeDef * adc,
uint32_t * scanId
)

Get a scan result and scan select ID.

Note
Only use if scan data valid. This function does not check the DV flag. The return value is meant to be used as an index for the scan select ID.
Parameters
[in] adc A pointer to the ADC peripheral register block.
[out] scanId A scan select ID of the first data in the scan FIFO.
Returns
The first scan data in the scan FIFO.

Definition at line 977 of file em_adc.c .

__STATIC_INLINE uint32_t ADC_DataScanGet ( ADC_TypeDef * adc )

Get a scan result.

Note
Check data valid flag before calling this function.
Parameters
[in] adc A pointer to the ADC peripheral register block.
Returns
Scan conversion data.

Definition at line 1110 of file em_adc.h .

__STATIC_INLINE uint32_t ADC_DataScanPeek ( ADC_TypeDef * adc )

Peek scan result.

Note
Check data valid flag before calling this function.
Parameters
[in] adc A pointer to the ADC peripheral register block.
Returns
Scan conversion data.

Definition at line 1128 of file em_adc.h .

__STATIC_INLINE uint32_t ADC_DataSingleGet ( ADC_TypeDef * adc )

Get a single conversion result.

Note
Check data valid flag before calling this function.
Parameters
[in] adc A pointer to the ADC peripheral register block.
Returns
Single conversion data.

__STATIC_INLINE uint32_t ADC_DataSinglePeek ( ADC_TypeDef * adc )

Peek single conversion result.

Note
Check data valid flag before calling this function.
Parameters
[in] adc A pointer to the ADC peripheral register block.
Returns
Single conversion data.

Definition at line 1092 of file em_adc.h .

void ADC_Init ( ADC_TypeDef * adc,
const ADC_Init_TypeDef * init
)

Initialize ADC.

Initializes common parts for both single conversion and scan sequence. In addition, single and/or scan control configuration must be done. See ADC_InitSingle() and ADC_InitScan() respectively. 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.

Note
This function will stop any ongoing conversion.
Parameters
[in] adc A pointer to the ADC peripheral register block.
[in] init A pointer to the ADC initialization structure.

void ADC_InitScan ( ADC_TypeDef * adc,
const ADC_InitScan_TypeDef * init
)

Initialize the ADC scan sequence.

See ADC_Start() for starting a scan sequence.

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.

Note
This function will stop any ongoing scan sequence.
Parameters
[in] adc A pointer to the ADC peripheral register block.

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.

__STATIC_INLINE void ADC_IntEnable ( ADC_TypeDef * adc,

[in] flags ADC interrupt sources to enable. Use a bitwise logic OR combination of valid interrupt flags for the ADC module (ADC_IF_nnn).

Note
This function does not clear event bits.
Parameters

Returns
ADC interrupt sources pending. A bitwise logic OR combination of valid interrupt flags for the ADC module (ADC_IF_nnn).

__STATIC_INLINE uint32_t ADC_IntGetEnabled ( ADC_TypeDef * adc )

Get enabled and pending ADC interrupt flags. Useful for handling more interrupt sources in the same interrupt handler.

Parameters
[in] adc A pointer to the ADC peripheral register block.
Note
This function does not clear interrupt flags.
Returns
Pending and enabled ADC interrupt sources. The return value is the bitwise AND combination of
  • the OR combination of enabled interrupt sources in ADCx_IEN_nnn register (ADCx_IEN_nnn) and
  • the OR combination of valid interrupt flags of the ADC module (ADCx_IF_nnn).

uint8_t ADC_PrescaleCalc ( uint32_t adcFreq,
uint32_t hfperFreq
)

Calculate the prescaler value used to determine the ADC clock.

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.
[in] hfperFreq Frequency in Hz of reference HFPER/HFPERC clock. Set to 0 to use currently defined HFPER/HFPERC clock setting.
Returns
A prescaler value to use for ADC in order to achieve a clock value <= adcFreq .
