|
|
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).
|
|
|
