5 Hardware Setup Guide

5.1 Power Configuration

There are 3 methods of powering the VM810C board.

1) USB Power(5V) - Connect USB power through micro-USB cable to CN2

2) DC IN(5V) - Connect 5V to CN1

3) J5 Power(5V) - Connect 5V to J5 pin 7

The following table summarise how to power the VM810C board using the various methods.

5.2 Backlight LED current Configuration

The VM810C module has backlight LED driver circuit on-board. The driver takes 5V as input power

source, and regulator the output voltage so that the total output current drawn by the backlight LED

chain is 60mA. This works fine with the 5” WVGA LCD provided with the VM810C50-D module (18 white

LED organized at 3 sets of 6 series LED).

If the user selects their own LCD panel to use with the VM810C board, the backlight LED current may

need to be re-configured to suite the LCD panel. By replacing the resistor R7 on VM810C PCB the

backlight LED current can be changed. The value of R7 is determined by following formula:

5.3 MPSSE Setup

To give a quick start with the VM810C development board, a Windows based Sample Application and

demo applications are provided for users to experiment and experience the FT810 in the VM810C system.

The following paragraphs provide a short description for development procedures.

MPSSE is a “multi-purpose synchronous serial engine” interface available in some FTDI device (e.g.

FT2232D, FT232H, FT2232H and FT4232H). This engine allows users to bridge from a USB port on a PC

to an SPI interface. Sample code is available for driving the FT810 over this interface with a FT232H

device that has been integrated into a cable. This device is available in the VA800A-SPI board, or

C232HM-EDHSL-0(5V) cable or C232HM-DDHSL-0(3.3V) cable.

VA800A-SPI is a MPSSE module accessory which can connect to the VM810C modules directly. Detailed

information of VA800A-SPI can be found at:
