| .. 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). |
| |
