ME817EV BT817
Evaluation Board
Datasheet
1 Introduction
The ME817EV is a customer evaluation board for
Bridgetek’s 4th generation EVE chip, BT817. The
ME817EV is used to develop and demonstrate
BT817’s graphics, touch and audio functionalities.
The board is capable of supporting LCD panels
with 40-pin LVDS interface, or 50-pin RGB
interface. Backlight LED current can be adjusted
using dip switches. Capacitive touch screens can
be connected to the board through a 10-pin or 6pin FPC connector. An Audio filter and amplifier
are included on-board, allowing a 1/8W speaker
to be driven. Audio source can be supplied from
the BT817, or through a line-in connector.
The ME817EV board supports 2 types of host
controller: MCU with SPI/QSPI master, or USB
host, selectable through dip switches. The SPI
option of the board behaves as a SPI slave, and
requires a SPI Master for proper micro-controller
interfacing and system integration. The USB
option of the board behaves as a USB High-speed
device using the FTDI FT4222H, and requires
control from a USB host through the Type-C
connector.
For a full list of the BT817’s features, refer to
the BT817_8 Datasheet.
1.1 Features

5 Hardware Setup
5.1 Power Configuration
There are 3 methods of powering the ME817EV board.
1) PC USB port Power(5V) - Connect to PC via Type-C cable to CN11
2) USBC charger Power(5V) - Connect USB charger with Type-C cable to CN6
3) Power from MCU host board(5V) - Connect 5V to CN8 pin 10 or CN7 pin 3&4
The following table summarises how to power the ME817EV board using the various methods.

5.2 Backlight LED current Configuration
The ME817EV module has a backlight LED driver circuit on-board. The driver takes 5V as an input power
source, and the regulator produces the output voltage so that the desired total output current can be
drawn by the backlight LED. Users can select backlight current up to a maximum of 280mA via dip switch
SW1. By default, with all the 4 switches in SW1 turned OFF, resistor R44 (2.4 Ohm) is setting the
minimum backlight current at 120mA. The switches in S12 are connected to array resistor RP9 (4 x 7.5
Ohm). Turning ON each switch will provide an additional backlight current of 40mA per switch.

5.4 Hardware Setup Example 1: MM900EV with 7” LCD
This example uses a Riverdi 7” TFT with CTP (RiTFT-70H-CAP) for display and touch functions. The host
controller will utilize Bridgetek’s MM900EV module built with FT900 32-bit MCU controller.
The RiTFT-70H-CAP outline size is the same as the ME817EV PCB. It is possible to put the LCD and PCB
together back-to-back to form a display module assembly.
Hardware Setup
Plug the USB Type-C cable into the CN6-USBC1 connector, with the other end plugged to a USB
power source (at least 1.5A current rating)
Trim variable resistors VR1-VR4 to get required LCD biasing voltages as: AVDD=9.6V, VGL=-6V,
VGH=18V, VCOM=3.8V.
Un-plug the USB Type-C cable to remove the power
Connect the LCD display 50-pin FPC cable to CN1
Connect the LCD touch 10-pin FPC cable to CN2
On SW2, set all 8 positions to OFF. On SW1, set SW1-1 to ON, SW1-2/3/4 to OFF
Set JP1 to short pin2-3
Connect the MM900EV module to CN8. A UMFTPD2A programming/debug module is also
recommended for programming the FT900.
Plug the USB Type-C cable to turn on the power
Software Setup
Download EVE Toolchains at https://brtchip.com/eve-toolchains/ .
Download EVE sample applications at https://brtchip.com/SoftwareExamples-eve/ .
Launch the Sample Application based on FT900 platform.
The BT81X Programming Guide describes the programming code and formats used by the BT81X. The
Sample Application is a well-formatted and documented program that illustrates the Programming Guide,
and provides numerous design examples and reference code demonstrations.

5.5 Hardware Setup Example 2: FT4222 with 10.1” LCD
This example uses an A-TOPS 10.1” 1280x800 TFT with CTP (AT-T101QIH-48CP) for display and touch
functions. The host will be PC, connected by utilizing the on-board FTDI FT4222H USB to QSPI bridge.
Hardware Setup
On SW2, set all 8 positions to ON. On SW1, set all 4 positions to OFF
Set JP1 to short pin1-2
Plug the USB Type-C cable to CN11-USBC2 connector, with the other end plugged to PC USB port (at
least 1.5A current rating).
Trim variable resistors VR1-VR4 to get required LCD biasing voltages as: AVDD=8.2V, VGL=-7V,
VGH=22V, VCOM=3.3V.
Un-plug the USB Type-C cable to remove the power
Connect the LCD display 40-pin FPC connector to CN9 through 40-pin FPC cable
Connect the LCD touch 10-pin FPC cable to CN12
Plug the USB Type-C cable to turn on the power
Software Setup
Follow section 5.4 to download EVE toolchain and sample application.
When re-compiling the sample application, select EVE_GRAPHICS_ME817EV in the Processor
Definitions of SampleApp MSVC Property Pages, as shown in the screenshot below. For more details,
please refer to the user manual of EveApps.
