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 6- pin 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.

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. Power Method CN11 CN6 CN8 Pin 10 (or CN7 pin3&4) JP1 PC USB port power (5V) 5V Must not connect Don’t care Short pin 1-2 USBC charger power (5V) Don’t care 5V Don’t care open MCU host board power (5V) Don’t care Must not connect 5V Short pin 2-3 Table 5-1 – Board power configuration

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 turn ed 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. Backlight LED array Vled voltage Vled current SW1 Number of ON position Comment 6 x 6 19.2V 120mA 0 8 x 3 9.6V 160mA 1 10 x 3 9.6V 200mA 2 12 x 3 9.6V 240mA 3 14 x 3 9.6V 280mA 4 Table 5-2 – Backlight LED configuration

5.3 Compatible LCD panel

The ME817EV supports 2 types of LCD interface: 1. LVDS panel with 40-pin 0.5mm FPC cable or connector 2. RGB panel with 50-pin 0.5mm FPC cable or connector Table 5-3 lists a few LCD panels which have been tested as working with the ME817EV board.

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.
