General Purpose Multi Media Controller

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 connection to PC or other USB host.

Comes with bezel with four mounting holes for easy system assembly.

3 Board Interface Description

The ME812AU-WH50R module is intended for direct use into existing applications that require a display.

This module is suitable for interfacing with a PC or other USB host.

3.1 Board Profile

Figure 3-1 – ME812AU-WH50R board bottom view

3.2 CN100- Micro USB receptacle

CN100 is a micro USB connector. When the USB host is connected, the host controls the ME812AU-WH50R module functions through the FT4222H USB-to-SPI bridge.

Pin No. Name Type Description

1 VBUS P USB VBUS +5V power supply

2 D- I/O USB D- data line

3 D+ I/O USB D+ data line

4 NC - No connection

5 GND P Ground

Table 3-1 – CN100 pin description




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

1 SP- O 8Ω speaker minus terminal

2 SP+ O 8Ω speaker plus terminal

3 AGND P Audio ground

4 AUD_IN I Audio Line IN

7 Getting Started

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.

Figure 7-1 – ME812AU-WH50R connects to USB host

7.2 Software Setup

Download the sample application for ME812AU-WH50R from the Bridgetek website at http://brtchip.com/eve-projects/

Install the FT4222H driver on a Windows PC. (downloadable at http://www.ftdichip.com/Products/ICs/FT4222H.html)

Launch the demo application from the PC.
