(

void

)

Basic example main executiont.

Basic example main execution.

Returns

ret - Result of the example execution. If working correctly, will execute continuously the while(1) loop and will not return.

Basic example main executiont.

• 50 ADC readings with delay.
• Threshold event (non-blocking).

  Returns

  ret - Result of the example execution. If working correctly, will execute continuously the while(1) loop and will not return.

  Basic example main executiont.

Returns

ret - Result of the example execution. If working correctly, will execute print the sample data.

Basic example main executiont.

Returns

ret - Result of the example execution. If working correctly, will execute continuously the while(1) loop and will not return.

Basic example main executiont.

Returns

ret - 0 on success.

Basic example main executiont.

Returns

ret - Result of the example execution. If working correctly, will execute continuously function iio_app_run and will not return.

Basic example main executiont.

Returns

ret - Result of the example execution. If working correctly, will execute continuously the iio_app_run and will not return.

Basic example main executiont.

Returns

ret - Result of the example execution. If working correctly, will measure active and reactive energy and RMS for channel A and for voltage stopping whenever an interrupt occurs and resulting in a stoppage of the measurement.

Basic example main executiont.

Returns

ret - Result of the example execution.

Basic example main executiont.

This example demonstrates basic ADMT4000 functionality by continuously reading sensor values and displaying them on the console.

Returns

0 in case of success, negative error code otherwise.

IIO descriptor and initialization parameter.

IIO app.

Declaring iio_devices structure

Initializing IIO app init param.

Initializing IIO app.

Running the IIO app (use iio_info or osc in terminal).

Set the threshold voltage to 5V

The comparator output will be available on the GPO_A pin

Set the DAC output on channel C to 5V

Measure input current on channel D
