zephyr/samples/drivers/misc/timeaware_gpio

.. zephyr:code-sample:: timeaware-gpio
   :name: Time-aware GPIO
   :relevant-api: tgpio_interface

   Synchronize clocks.

Overview
********

A sample application that can be used with any supported boards. eg. RPL.
prints configuration info to the console. Below functionalities are tested:

1. Periodic pulse generation (an Oscilloscope or loopback may be required)
2. Input pulse timestamping (a pulse generator or loopback may be required)

Building and Running
********************

This application can be built and executed as follows:

.. zephyr-app-commands::
   :zephyr-app: samples/drivers/misc/timeaware_gpio
   :board: intel_rpl_crb
   :host-os: unix
   :goals: build


To build for another supported board, change "intel_rpl_crb" to that board's
name (if supported).

Sample Output
