.. 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).
