AVR UC3 Series Software Framework: General-Purpose Input/Output (GPIO) Driver

Copyright © 2007 Atmel Corporation

Introduction

The General-Purpose Input/Output (GPIO) gives access to the MCU pins. The GPIO can be interfaced through a peripheral bus or the local bus.

 

GPIO Software Driver

This driver provides an API to get access to the main features of the GPIO controller.

 

The driver is composed of gpio.c and gpio.h (for accurate API description, read this header file).

 

GPIO Software Driver Examples

Two examples are currently available:

  • demonstrates the peripheral bus interface;
  • demonstrates the local bus interface.
  •
