7Overview
8********
9
10This sample application gets the output of a gesture sensor (PAJ7620) using either polling or
11triggers, and outputs the corresponding gesture to the console, each time one is detected.
12
13Requirements
14************
15
16To use this sample, the following hardware is required:
17
18* A board with I2C support (and GPIO to detect external interrupts in trigger mode)
19* PAJ7620 sensor

24This sample outputs data to the console. It requires a PAJ7620 sensor.

35Trigger Mode
36============
37
38In trigger mode, the sample application uses a GPIO to detect external interrupts, therefore GPIO
39support must be enabled. Just like every sensor supporting trigger mode, it is possible to choose
40between using a global thread (``CONFIG_PAJ7620_TRIGGER_GLOBAL_THREAD``) or a dedicated thread
41(``CONFIG_PAJ7620_TRIGGER_OWN_THREAD``) for the interrupt handling.
