XMEGA AES xplain example3 Documentation

Introduction

This simple example shows how to use the Advanced Encryption Standard (AES) to encrypt 128-bit data with DMA support.

Main Files

• aes.c AES driver implementation
• aes.h AES driver definitions
• aes_example3.c AES driver example application

Device Info

All AVR XMEGA devices with AES crypto module can be used. This example have been tested with the following setup:

• Xplain
• XMEGA A1 Xplained
• XMEGA A3BU Xplained

Description of the example

The example will initialize the AES and use the xplain LEDS to show the AES operation results. DMA support is used in the example.

Dependencies

This example depends on the following modules:

• Advanced Encryption Standard (AES)
• General Purpose Input/Output for LED output
• Programmable Multilevel Interrupt Controller for interrupt handling
• Sleep manager for sleep management
• Direct Memory Access controller (DMA) for DMA support

Compilation info

This software was written for the GNU GCC and IAR for AVR. Other compilers may or may not work.
