1.0 INTRODUCTION
This document is a ‘Quick Start Guide’ for LPC1830-Xplorer; a cost effective evaluation platform for
NXP’s LPC18xx MCU. This document focuses on the kit contents, board verification, possible debuggers
and IDEs that can be used.
1.1 LPC1830 Xplorer Ordering Options
Option A: With ULINK-ME debugger
This option is recommended for customers that do not already have a suitable debug probe.
The Xplorer is packaged as shown in the image below.
TBD
Fig. 1
After unboxing the package you should find Xplorer Board, ULINK-ME, 2 ‘USB AM to Micro B’ cable
and ‘USB AF to Micro B’ cable as shown in the following image.

Option B: Without the debugger
This option is recommended for customers who already own and wish to use a debugger such as.
•ULINK2 with KEIL uVision
•NXP LPCLink with LPCXpresso
•Red Probe+ with Red Suite from Code Red
•I-jet with IAR Embedded Workbench
•Segger JLink with IAR Embedded Workbench or KEIL uVision
The Xplorer is packaged as shown in the following image.

1.2 ARM JTAG (20-pin) to Cortex JTAG (10-pin) Adaptor
Please note that your existing debugger might be supporting only the ‘20-pin ARM JTAG connector’. In
such scenarios one would require a ‘20-pin to 10-pin adaptor’ and the necessary cables. The Xplorer has
on board ‘Cortex SWD/JTAG 10-pin male connector’, the ‘20-pin to 10-pin adaptor’ is not a part of the
Xplorer package and user needs to buy them separately.
If the debugger supports the ‘10-pin Cortex header’ one needs to have the 10-pin ribbon cable and can
directly connect to the Xplorer. Please note even the 10-pin ribbon cable is not a part of standard delivery
and needs to be procured separately.
The picture below shows 20-pin ribbon cable, 10-pin ribbon cable and ‘20-pin to 10-pin adaptor’.

1.3 ULINK-ME and KEIL
Connect one end of 10-pin ribbon cable ‘ULINK-ME 10-pin box header’ and other end to Xplorer as
shown in the below image. The hardware setup is now ready for programing an Xplorer board with
ULINK-ME and KEIL IDE. Please refer keil knowledgebase article for connecting ‘ULINK-ME 10-pin
ribbon cable’ to NGX Xplorer.

1.4 ULINK2 and KEIL
Connect ‘ULINK2 20-pin cable’ to ‘20-pin to 10-pin adaptor’ and connect one end of 10-pin ribbon cable
to ‘20-pin to 10-pin adaptor’ and other end to Xplorer as shown in the below image. The hardware setup
is now ready for programing an Xplorer board with ULINK2 and KEIL IDE. Please refer keil
knowledgebase article for connecting ULINK2 to NGX Xplorer.

1.5 NXP-LPCLink and LPCXpresso
Separate the LPCXpresso controller part and use only the NXP LPCLink as shown in the following image.
Fig. 8
The Xplorer board has on board ‘Cortex SWD/JTAG 10-pin box header’; connect one end of the 10-pin
ribbon cable to NXP LPCLink and other end to Xplorer. Make sure the 10-pin ribbon cable notch on the
connector is facing towards the arrow mark on the NXP LPCLink. The hardware setup is now ready for
programing an Xplorer board with NXP LPCLink and LPCXpresso.
2.0 LPC1830-Xplorer Overview
2.1 Introduction
The NGX LPC1830-Xplorer is a compact and versatile evaluation platform for the NXP's Cortex-M3
based MCUS. NGX's evaluation platforms are generally not tied up to any particular debugger or
compiler/IDE. However it is not practical to test and ensure that the solution would work out of box with
all the available debuggers and compilers/IDE. As long as the compiler supports the particular MCU and
the debugger supports the standard debug interfaces like the SWD/JTAG you can use this platform with
any tool. The board is supported by extensive sample examples allowing you to focus on the application
development.

3.0 LPC1830-Xplorer verification
NGX's evaluation platforms ship with a factory-programmed test firmware that verifies all the on-board
peripherals. It is highly recommended that you verify the board, before you start programming. Also this
exercise helps you get acclimatized with the board quickly.
To run the tests you will need the following:
•LPC1830-Xplorer
•Power: USB cable (you can power it through either port, we recommend to use USB1 for the
verification) or external power supply (Alternatively the Xplorer has a 5V in pin available for
powering through external power source)
•PC: With Windows7 or XP (32-bit)
•One USB AM to Micro B cable in addition to the one provided with the KIT
•Micro SD card
•2-GB USB pen drive
•Audio-in (Auxiliary) cable (3.5mm diameter connector)

3.2 Powering the Board
The LPC1830-Xplorer can be powered through USB; we can either power it from USB0 port or USB1
port. It is highly recommended that the user tests all the peripherals as soon as the board is received. A
regulated supply can be supplied to the 5V pin on the Xplorer-LPC1830 header.
Note: The USB power can source only up to 500 mA of current. For applications having higher current
requirements we recommend to use an external power supply. Please note that the external power supply
is not a part of standard delivery.
3.3 Verifying all the peripherals on LPC1830-Xplorer
The following section focuses on the verification of all the peripherals supported on the LPC1830Xplorer.
The order of the tests is mentioned in the same manner as the flow of the test firmware. We highly
recommend that you follow the order of the test. The test firmware is designed in a manner that the user
needs to spend as minimum time as possible to verify all the on-board peripherals. The test firmware
executable resides on the Quad Flash. The BOOT select switch is configured to execute from the Quad
Flash interface.
Note: The test firmware “Debug Messages” or flow might be changed in due course. Generally these are
only cosmetic changes so that the usage is easier. If you observe a different message than the one
mentioned in the Manual, do not worry and please proceed with the test.
Important Note: The user needs to press the RESET switch twice to be able to reset the controller. This
is due to the issue with the silicon. However for the power up reset (USB power cycle) the controller
boots up fine.
Power up the board over USB1 port and we are all set to verify the LPC1830-Xplorer peripherals. Before
we get to the verification we need to install the Virtual COM port drivers needed for the LPC1830-Xplorer
(USB1 port) to appear as a Virtual COM port (Used for viewing the debug messages on serial emulation
tool). Fortunately, this is a one-time setup and fairly simple. On a Windows machine the user needs to
point to the location of the INF file. Download INF file Click Here
Steps to install the VCOM drivers on windows 7 machine:

Quick Start Guide: LPC4330-Xplorer
Page | 14
Step 1: Connect USB1 to the computer, Open device manager, you can find “NXP LPC18xx VCOM” new
device listed under ‘Other devices’.
Fig.12
Step 2: Right click on the “NXP LPC18xx VCOM” and then left click on ‘Update Driver Software’.
Fig.13

Step 3: Click on Browse my computer for driver software.
Fig.14
Step 4: Click Browse, select downloaded LPC1830_Xplorer_VCOM_inf unzipped driver folder and then
click on OK.

Step 5: Click on Next to continue driver installation.
Fig.16
Step 6: Click on ‘Install this driver software anyway’.

Step 7: The ‘LPC18xx USB VCom driver’ is successfully installed, click on close.
Fig.18
Step 8: Now ‘LPC18xx USB VCom Port’ (COM12) is ready to use.
Fig.19
Note: The Virtual COM is listed under the device manager. Please note that the COM port list under the
Device Manager is automatically updated with the COM port number for the Virtual COM. On our test
machine we see two COM ports listed COM1 and COM12. COM1 is the actual COM port and COM12 is
the virtual COM port. The COM12 will appear only if the Xplorer board is connected (USB1) to the PC.
Every time the Xplorer is reset the user needs to close the Hyper Terminal application and restart it
again.

3.3.1 LEDs
Test setup and verification:
As soon as the Xplorer is turned ON or reset; the test LEDs go ON & OFF for a couple of times, this
simple test validates the LEDs. The Xplorer has one Green LED and one Blue LED. These LEDs are also
connected to the outputs of the SCT lines. Please refer to the schematics for more details.
3.3.2 USB1 (Virtual COM port)
Test setup and verification:
For the very first time the windows machine will ask for the appropriate virtual COM drivers to be
installed.
Steps to select ‘USB1 VCOM port’ on HyperTerminal in windows 7 machine:
Step 1: Open a HyperTerminal, type name and click on OK.
