Function Documentation

example_main()

int example_main

(

void

)

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 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 execution.

Returns

ret - Result of the example execution. If working correctly, will execute continuously function iio_app_run 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
