CHAPTER 2 SETTING UP THE MOD-LCD4.3 BOARD
2. Introduction to the chapter
This section helps you set up the MOD-LCD4.3 development board for the first time.
Please consider first the electrostatic warning to avoid damaging the board, then discover the
hardware and software required to operate the board.
The procedure to power up the board is given, and a description of the default board behavior isdetailed.

2.1 Electrostatic warning
MOD-LCD4.3 is shipped in a protective anti-static package. The board must not be exposed to highelectrostatic potentials. A grounding strap or similar protective device should be worn whenhandling the board. Avoid touching the component pins or any other metallic element.

2.2 Requirements
In order to set up the MOD-LCD4.3, the following items are required:––

A source of power applied to at least one of the following:– mini USB – standard 5V––

PWR JACK - 9-12Vdc or 6-9Vac
JTAG – 5V from the JTAG debugger––

UEXT – 3.3V from external host device connected to the UEXT
EXT1/EXT2 – 5V applied directly

A programmer that has 20 pin interface and supports programming of LPC2478

You may use any of Olimex’s ARM-JTAG programmer/debugger (For example ARM-USB-TINYH) for this task.
Also, a host-based software toolchain is required in order to program/debug the MOD-LCD4.3
board. There are also a number of ready IDEs available like IAR Embedded Workbench, Rowley
CrossWorks, etc.

MOD-LCD4.3 User's Manual

Olimex also maintains own distribution of GCC and Eclipse suitable for use with our programmers.

2.3 Powering the board
On powering the board the PWR LED, the SD LED and the display should turn on. After that thetouchscreen should show a simple color palette and a mouse pointer that responses on dragging.
If measuring the current consumption it should be around 15 mA.

2.4 Prebuilt software
On arrival the board has a basic demo installed which features test of the LEDs, the color range andthe touch response of the LCD, the SD card slot and the USB connectivity.

6.2 UEXT
MOD-LCD4.3 board has UEXT connector and can interface Olimex's UEXT boards adding display
and SD card functionality. Of course the board can be used standalone.
Note that the first batch of MOD-LCD4.3''+ (LPC1788) were send with an UEXT cable suitable forthe board only to act as a HOST to other MOD boards. Later batches are shipped with cable pins 3
and 4 reversed so the board can be used as device. To make it is manually host or device swap 3 and4 respectively. Without swapping by default the board is configured as a HOST to other MOD
boards.
