1. INTRODUCTION:

LPC176x HPLUS EX is optimized to save development time in typical embedded control

applications. The board allows the evaluation of the LPC176x series devices. It is an extension of

an LPC176x HPLUS and has a few important peripheral interfaces assembled for evaluation and

testing. The remaining interface options are given out for the external interface via standard

2.54mm berg connectors.

The functional details of the board are as follows-

USB Device and Host Connectivity Options.

Onboard 2 Serial Ports. (UART0 and UART3)

128x64 Pixels Graphical LCD connectivity port (Graphical LCD is not the part of the Board,

needs to be brought separately)

2. HANDLING WARNINGS: The Kit must not be subjected to high electrostatic potentials.

General practice for working with static sensitive devices should be followed when working

with the LPC176x HPLUS EX.

Board must always be handled at properly designated work areas.

When not being used, the board must be enclosed in the box and stored safely.

Avoid touching the circuits or components.

Stacking of circuit boards and assemblies should be avoided to prevent physical damage

3. KIT DELIVERABLES: LPC176x HPLUS EX Board.

USB Cable. (AB)

CD that contains, KEIL evaluation version installer, Flash Magic Installer, schematics, user

manual and related documents, hex files for experiments, Keil project and workspace for

implementing various peripherals and few example project codes.

4. BOARD USE REQUIREMENTS: To test and evaluate the board, we recommend the following configurations

PC with 2.0 GHz or higher CPU, 512 MB or above RAM, USB Port, Serial Port and

Ethernet Port. (Will need a Parallel Port if a Parallel JTAG is being used)

Operating System (We recommend Windows XP, since most of our testing is done on

same platform, although other OS can also be used)

Integrated Development Environment (We recommend Keil 4. Other compatible IDE can be

used)

Debugging/Programming Tool (We recommend HJTAG, Other compatible tools can be

used)

To test all the features of the board, you would also require a USB Cable (A to B), Ethernet

cable (straight), a Micro SD Card, DC power jack (7.5V-9V/1Amp DC). If you also need to

test the TFT, you will need a 3.2 inch TFT Board provided by CoiNel.

7. HARDWARE RESOURCES:

BOARD Connections

The above figure shows the connectivity options available on LPC176x HPLUS EX.



8. I/O CONNECTOR DESCRIPTION:

The details of the IO connections are as follows

8.1. DC Power Input: The Power supply to be used has to be 7.5V to 9V DC, 1Amp. The DC jack connectivity

details are shown in the figure.

A slide switch is provided for power ON/OFF control. The slide switch is useful only when

an external DC adapter is used. When USB is used to power the board, the switch condition will

not have any effect on the power input.

When using the adapter, sliding the switch towards the arrow shown in figure will turn the board

ON.



8.2. JTAG 20 Pin Box Header: The box header will be used to connect the JTAG for Debug/Programming. A 20 Pin IO

Cable can be connected here which connects from a Parallel/USB JTAG. For more details on

JTAG, check www.coineltech.com

8.3. Micro SD Card Connector: The correct way of inserting the SD card is given below. The SD Card is connected to SPI0

Pins via jumpers. Pressing the card in the direction shown will lock the card once it will fully and

properly inserted.

Note: To remove the card, press the card gently in the same direction shown above and then

letting it loose. The card will easily pop out and can be removed.



8.4. Ethernet: The correct way to plug the connector is given in the figure. Press the connector in the

direction shown and the connector will lock up properly when it is fully connected.

An Ethernet straight through cable is used for testing. The recommended connection of the

cable is also given.



8.5. USB CONNECTIONS:

The USB provided can either be used as a HOST or an End Device. The USB A Connector

is used for the HOST interface, while USB B type for the end device. The jumper setting at J15

needs to be changed depending on whether the USB is used as a HOST or End Device.

The details of connections are given below.



8.6. Analog Input:

8.7. Reset and ISP Switch:

These switches provided can be used for resetting the CPU and ISP (In system

programming) mode. The details of programming the board in ISP mode is given in detail in

programming section.



8.8. Serial Ports: Onboard 2 Serial ports are provided i.e. UART0 & UART3. The signals are RS232 logic

compatible, so it can be directly connected to Computer Serial Port. The UART0 can be used for

ISP mode programming. The ISP mode programming detail is provided in programming section.

The UART module number is written on the rear side of the board below RS232 connectors.

8.9. Graphical LCD Connector: 128x64 Pixels Graphical display can be directly connected to this connector. All the

graphical LCD’s are not compatible. The Compatible Graphical display is available at

www.coineltech.com/shop



8.10. TFT 14 pin BOX Header:

This connector can be used to connect the 3.2 inch TFT provided by CoiNel. The details of

the TFT can be found at the company’s website.

The 3.2 inch TFT can be found at http://www.coineltech.com/shop

These TFT Displays are SPI based and if the user needs, the same connector can be used

for connecting other devices that use SPI.

mm Berg Connectors for easy external interface. The pin out descriptions of each Berg

connectors is written beside the pin.

Check the details of pin out below.

J4 and J5 is a GPIO connectivity header, the pin description are shown. The pin details are

also written beside the pins.



9. VALIDATING LPC176x HPLUS EX: 9.1. Powering the Board:

The board can be powered using an adapter or through the USB. Connect the adapter

(7.5V-9V/ 1 Amp) to the DC Jack provided and slide the switch towards ON Position. The details

are shown below.

You can also power the board using USB by connecting the USB A to B Connector as

shown.

When the Power is applied, the POWER LED (D6 beside the DC Jack) will turn ON indicating

board power up.

Note: To test the board for the first time, you can use only USB for powering the board.



9.2. Detecting the USB:

The LPC176x HPLUS EX comes with a preloaded program to test LED and USB End

device functionality.

To test this, you need to open Device Manager.

The operating system used is Windows XP.

Steps to open Device Manager are as follows-

1. Right click on My Computer and left click on Manage Options as shown below



2. A computer management window will pop up as shown below. Left Click on Device Manager

and on the right window you will see your computer information.



3. Connect the USB cable (A to B type) to the PC and B side to LPC176x HPLUS EX Board. You

will see that the TEST LED will blink 5 times and at the 6th time, the test led will be ON

continuously and the USB LEDs (D8 and D9) will be ON once the USB is enumerated as the end

device and you will see that the device is detected as a human interface device and this can be

seen on the device manager. The changes seen in the device manager will be as follows.

The changes above indicate the board has been detected as a HID. One you see this you would

have evaluated the board for the first time.

Note: You can remove and re plug the USB or press reset switch to check and see the changes

all over again.



10. ISP MODE PROGRAMMING: You need to have LPC176x HPLUS EX Board, Serial cable, Desktop PC, Flash Magic

Software and precompiled Hex File.

Follow the Steps is below:

Power ON LPC176x HPLUS EX Board.

Connect Serial Cable Between UART0 of Module and PC.

Enter into the ISP Programming mode by following procedure.



Open Flash Magic Software in PC.

Click on Options and select Advance Options.

In Advance Options Keep the Settings as shown below.

Click on OK after making changes

Keep the Settings as below in Flash Magic and Click on Start to program.

COM Port may not be COM1 in every PC, Check it in Ports (COM & LPT) in

Device Manager.



If All the Settings are proper, the programming will be successful.
