Quick Start Guide for the GPIO driver

This is the quick start guide for the group_sam_drivers_gpio, with step-by-step instructions on how to configure and use the driver for a specific use case.

The use cases contain several code fragments. The code fragments in the steps for setup can be copied into a custom initialization function, while the steps for usage can be copied into, e.g., the main application function.

Use Cases

• GPIO Interrupt Usage

GPIO Interrupt Usage

This use case will demonstrate how to configure a pin(PC03) to trigger an interrupt on SAM4L-EK board.

Setup Steps

Prerequisites

This module requires the following service:

• Clock management
• Common IOPORT (for GPIO)
