Description

Analog to Digital Converter Interface.

Function Documentation

ADC_ConversionDone()

int32_t ADC_ConversionDone

(

void

)

Check if conversion finished.

Returns

• 0: conversion finished
• -1: conversion in progress

The function checks whether the conversion has finished. The function returns an integer value of 0 when conversion has finished, and -1 when conversion is in progress.

ADC_GetResolution()

uint32_t ADC_GetResolution

(

void

)

Get resolution of Analog-to-Digital Converter.

Returns

Resolution (in bits)

The function returns the number of bits of the A/D converter.

ADC_GetValue()

int32_t ADC_GetValue

(

void

)

Get converted value.

Returns

• >=0: converted value
• -1: conversion in progress or failed

The function returns the converted value from the A/D converter. The function returns -1 when the conversion failed or is still in progress.

ADC_Initialize()

int32_t ADC_Initialize

(

void

)

Initialize Analog-to-Digital Converter.

Returns

• 0: function succeeded
• -1: function failed

The function initializes the A/D converter interface. The function returns an integer value of 0 on success, and -1 on error.

ADC_StartConversion()

int32_t ADC_StartConversion

(

void

)

Start conversion.

Returns

• 0: function succeeded
• -1: function failed

The function starts the A/D conversion. The function returns an integer value of 0 on success, and -1 on error.

ADC_Uninitialize()

int32_t ADC_Uninitialize

(

void

)

De-initialize Analog-to-Digital Converter.

Returns

• 0: function succeeded
• -1: function failed

The function de-initializes the A/D converter interface. The function returns an integer value of 0 on success, and -1 on error.
