Tizen(Headed) Native API  6.5

The ADC API provides functions to control ADC peripherals connected to the IoT device.

Required Header

#include <peripheral_io.h>

Overview

This ADC API provides functions to control ADC peripherals connected to the IoT device.

Realted Features

This API is related with the following feature:

It is recommended to use features in your application for reliability.

You can check if a IoT device supports the related features for this API
by using System Information, and control your application's actions accordingly.

To ensure your application is only running on the IoT device with specific features,
please define the features in your manifest file using the manifest editor in the SDK.

More details on featuring your application can be found from Feature Element.

Functions

int peripheral_adc_open (int device, int channel, peripheral_adc_h *adc)
 Opens the ADC pin.
int peripheral_adc_close (peripheral_adc_h adc)
 Closes the ADC pin.
int peripheral_adc_read (peripheral_adc_h adc, uint32_t *value)
 Gets the current value of the ADC pin.

Typedefs

typedef struct _peripheral_adc_s * peripheral_adc_h
 The handle of the ADC peripherals.

Typedef Documentation

typedef struct _peripheral_adc_s* peripheral_adc_h
