5+
Use the PSI5 (Peripheral Sensor Interface) driver.
6+
7+
Overview
8+
********
9+
10+
The sample application shows how to use the :ref:`PSI5 API <psi5_api>`:
11+
12+
* Receive data
13+
* Transmit data
14+
15+
Requirements
16+
************
17+
18+
This sample requires a PSI5 sensor to be connected and exposed as ``psi5-0`` Devicetree alias.
