1 INTRODUCTION

This user manual contains specifications and information on how to use the simple AV
system board.

2 OVERVIEW OF SIMPLE AV SYSTEM BOARD

The simple AV system board plays the following 2 types of music media files and performs 1 type of image output. Music media files are however not played simultaneously; The format of played music file is set in accordance with compile options.
① MP3/JPEG
JPEG files in a USB memory are imported by the file system, and the data decoded by the JPEG encoder/decoder are output and displayed on the LCD. The MP3 file to be played is selected on the touch panel. It is then imported from the USB memory by the file system, and is played by outputting the data decoded by the MP3 decoder to the DAC. You can select and play MP3 files by switch operation as well.
② AAC
The AAC file to be played is selected by switch operation and the AAC file is imported from the USB memory by the file system. The imported AAC file is decoded by AAC decoder and the data is output to the DAC and played. If playing an AAC file, image output to the LCD and touch panel control do not work.

3.4 Power Supply Method USB bus power of the PC is used as the power supply for the simple AV system board. Connect the Type A side of the USB cable (with Type A - Type B connector) to the USB

port of the PC and connect the Type B side to the USB power supply connector of the simple AV system board.
Press down the power switch with the USB cable connected. The power supply switch is
self-locking and stays depressed while the power is on. To turn the power off, press the power switch again.
