.. zephyr:code-sample:: paj7620_gesture
   :name: PAJ7620 Gesture Sensor
   :relevant-api: sensor_interface

   Get hand gesture data from PAJ7620 sensor.

Overview
********

This sample application gets the output of a gesture sensor (PAJ7620) using either polling or
triggers, and outputs the corresponding gesture to the console, each time one is detected.

Requirements
************

To use this sample, the following hardware is required:

* A board with I2C support (and GPIO to detect external interrupts in trigger mode)
* PAJ7620 sensor

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

This sample outputs data to the console. It requires a PAJ7620 sensor.

Polling Mode
============

.. zephyr-app-commands::
   :zephyr-app: samples/sensor/paj7620_gesture
   :board: nucleo_f334r8
   :goals: build
   :compact:

Trigger Mode
============

In trigger mode, the sample application uses a GPIO to detect external interrupts, therefore GPIO
support must be enabled. Just like every sensor supporting trigger mode, it is possible to choose
between using a global thread (``CONFIG_PAJ7620_TRIGGER_GLOBAL_THREAD``) or a dedicated thread
(``CONFIG_PAJ7620_TRIGGER_OWN_THREAD``) for the interrupt handling.
