1 Introduction

The ME812AU-WH50R is a development module for Bridgetek’s FT812, Embedded Video Engine (EVE) graphics controller IC. This module behaves as a USB device, with an FT4222H USB to SPI bridge built on -board so that the module can be accessed from a PC or any other USB host. The ME812AU-WH50R module includes a 5.0 inch 800*480 TFT LCD panel with resistive touch screen, and an audio amplifier to drive 8Ω speaker.

1.1 Features

The ME812AU-WH50R module utilises the FT812, Bridgetek’s 2nd generation EVE chip . Graphic, audio and touch functions of the FT812 can be accessed with the ME812AU-WH50R. For a full list of the FT812’s features, refer to the FT81x datasheet. The ME812AU-WH50R has the following features:  Ready to use 5 inch WVGA LCD module.  Supports portrait and landscape display mode.  Bright backlight LED with dimming.  Supports resistive touch with pressure sensing.  Supports mono audio from the FT812 or an external source.  On board audio amplifier for an external 1W speaker.  Support USB bus power.  Support USB high speed connecti on to PC or other USB host.  Comes with b ezel with four mounting holes for easy system assembly.

3.3 CN13- Audio connector

The ME812AU-WH50R supports a mono speaker output through CN13. A PWM audio signal from the FT812 goes through a 3-stage RC filter and the audio amplifier, to drive into the 8Ω speaker if connected. Maximum output power to the speaker is 1 Watt. A readymade speaker module (CleO-SPR1) is available from Bridgetek. An alternative, mono line-in audio input is also provided on CN13. Users can drive their own audio source in to the on board power amplifier. Pin No. Name Type Description

7.1 Hardware Setup

Error! Reference source not found. shows the ME812AU-WH50R module connected to the PC USB host port or self -powered hub port through a USB cable (suggest FTDI accessory VA -FC-1M-BKW or VA- FC-1M-BLW). The 1W speaker is optional (suggest Bridgetek accessory CleO-SPK1). Note that if the 1W speaker is used, the USB power shall be able to supply at least 900mA current.
