Function Documentation

example_main()

int example_main

(

void

)

IIO trigger example main execution.

Basic example main execution.

Returns

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

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

Initialize the ADC_RDY GPIO and associated IRQ event

Returns

0 if success, negative error code otherwise

Negative temperature

Positive temperature

Negative temperature

Positive temperature
