peripherals of the board and provide power to the peripheral interface.
2.0 Features
• 480x272 Graphics LCD with touch & back light
• Two Test LEDs
• Power Jack
• Power Switch
• Reset Button
• ISP Button
• ADC Pot
• RTC battery
• 6-buttons Keypad
• Serial Connector 0
• Serial Connector 1
• Serial Connector 2
• Serial Connector 3
• GPIO brought to header pins
Note: Features are dependent on the Xplorer++ boards.
3.0 Getting Started
Before starting you would need the following things handy and ready. For compiling and running
programs refer to LPC185x/LPC435x-Xplorer++ User manual.
4.0 Requirement
The requirement is put in two sections.
Hardware
• Power adapter – rating 7.5 V, 1 AMP
• Serial cable
• Micro USB cable
• LPC435x/LPC185x-Xplorer++ board
User Manual: LPC435x/LPC185x-Xplorer++ with BaseBoard

Software
• PC with Windows OS
• Use HyperTerminal as terminal software
• Coflash
• Test Binaries of LPC435x/LPC185x-Xplorer++ board
5.0 Setup
Mounting the LPC435x/LPC185x-Xplorer++ Board
The LPC435x/LPC185x-Xplorer++ board should be mounted on the BaseBoard with a particular
alignment.
Note: Improper mounting of the Xplorer++ board on BaseBoard may damage the Xplorer++ board and
/ the BaseBoard.
The pin 1 of J10 on Xplorer++ board should be aligned with the pin 1 of J4 female header on BaseBoard.
Refer to the marking as shown in the image below.

6.0 Validating the BaseBoard
Note: You need to flash the Xplorer++ board with the required firmware according to the functionality.
TEST_LEDs
Blinky – This blinks the Test LEDs LED2 and LED3 on the BaseBoard.
LCD
LCD – Reset the board and “NGX Technologies” is displayed on the LCD screen as shown in the
following image.
Touch on crosshair to verify LCD touch.
UART0 to UART3
Test setup and verification:
Open the hyper terminal as shown in the below image. To test the UART open the hyper terminal with
settings 115200 bps 8N1, i.e.
Baud Rate: 115200 bps
Bits: 8
User Manual: LPC435x/LPC185x-Xplorer++ with BaseBoard
Page | 7
Parity: None
Stop bits: 1
Flow Control: None
A ‘Connect To’ window opens where you have to select the COM port. In this example it is COM1. Click
OK. A ‘COM1 Properties’ window appears. Set the values as shown below. Click OK.
Note: Please check for your machines COM port number. The COM port number can be different.

Next a ‘Hyper Terminal’ window opens as shown below.
Make sure the board is powered and the serial port is connected to the board. The key that are typed on
the keyboard are echoed back to the hyper terminal.
First connect serial cable to UART0, type the key on the keyboard that will echo back to the hyper
terminal, this verifies the UART0, press ESC to terminate the demo. Follow the same procedure to test
UART1, UART2 and UART3.
Note: UART0 and UART1 are exchanged on the Baseboard.

ADC
Test setup and verification:
Open the hyper terminal as shown in the below image. To test the ADC open the hyper terminal with
settings 9600 bps 8N1, i.e.
ADC value display via USB Virtual Com port, for installing and opening LPC185x/LPC435x USB VCom
port please refer the LPC185x/LPC435x-Xplorer++ Quick Start Guide
After opening the USB VCom port, press User Switch on the Xplorer++ board then menu will display as
