Installation
of NXP's ARM Cortex M0 based LPCXpresso development board
With the 32- bit micorcontrollers becoming popular and
also the kits/boards available at affordable prices, we
at EE Herald bringing you new modules on embedded systems
design practice. The idea is to provide you the inexpensive
32-bit MCU based latest hardware boards. We have selected
ARM Cortex M0 based boards: LPCXpresso development board
from NXP Semiconductors and STM32F0 Discovery from ST
MIcroelectronics. Both the boards we have suggested here
are available in India. Below is the installation and
program execution guide with one simpe program for NXP's
LPCXpresso board.
1. 1 PC system requirements for LPCXpresso
kit installation:
Operating System: Microsoft Windows - XP 32-bit
(SP2 or greater)/MicrosoftWindows - Vista 32-bit or 64-bit
/MicrosoftWindows - Windows 7 32-bit or 64-bit /Linux
- Ubuntu 9, 10, and 11 /Linux - Fedora 12 and 13
System RAM: 512 MB minimum (1 GB recommended)
Hard Disk: 300+ MB of available space.
Screen/Display Adaptor: 1024x768 minimum recommended
Internet Connection: High-speed internet is recommended
to download and register the software
1.2 Hardware requirements:
1. LPCXpresso development board (In the previous module
we have provided link to buy this kit).
To buy this kit or to learn more visit NXP website http://ics.nxp.com/lpcxpresso/
The cost of the kit is around 2000/- Rupees
2.USB 2.0 A/Mini-B cable
1.3 IDE software installation and running
the sample program:
1. You got to to download the LPCXpresso tool at http://lpcxpresso.code-red-tech.com/LPCXpresso/
by creating your account by providing your email id .
2. Password will be sent to you by e-mail. then open http://lpcxpresso.code-red-tech.com/LPCXpresso/
link and login to your account and follow the instructions
to download LPCXpresso installer.
3. Select the right Operarting System (OS) and also the
latest version. The size is around 417mb at normal broadband
speed, its takes few hours to complete download.
2.Installation process:
Double-click the LPCXpresso installer file after downloading.
Then click "next" on the setup wizard which
looks like below.
Read the license agreement and then click on the radio
button before the text-line "I accept the agreement"
(if you accept the agreement). Also Click on the next
button to continue installation (in the window appears
as shown in the picture below).
The below picture will appear for some time before the
LPCXpresso installation is complete!
3 Activation
To activate your product from LPCXpresso, Open LPCXpresso
choose Help->Product activation->Create serial
number and register. Once the wizard is open, click
"Copy to clipboard" to copy the LPCXpresso serial
number into the clipboard., but contains no personally
identifiable information. Now click the button to open
the registration activation page. This
should display a web form. After completing the form,
you will receive an activation code via email within a
few minutes. Highlight the activation code in your email
program, and select Copy to place it into the Windows
clipboard. Now, choose select Help->Product activation->Enter
activation code from within LPCXpresso. Paste the
product activation code into the Product activation dialog
by right clicking in the Activation code field and choosing
"Paste." Then click the "OK" button.
You should receive a dialog confirming acceptance of the
activation code. It is also possible to complete LPCXpresso
activation on a PC that is offline as long as another
PC has access to the Internet.

Running a sample program
on the board:
4.1 Downloading NXP sample code from the web
4.1.1. First, select "Import project(s)" from
the Quickstart panel in the lower left corner of the
screen
4.1.2. Next, select "Browse for more examples…"
from the Import project(s) dialog
.
4.1.3 The LPCXpresso-Support web page should appear.
It has links to NXP sample code that has been developed
for LPCXpresso. Select the sample code that applies to
your Target Device and download it. Then, switch back
to LPCXpresso and use the Browse button to select the
.zip file.
4.1.4 Now click the Next button and then choose which
projects to import from the .zip file.
4.1.5 Often, there will be references between projects
in a .zip file so it is best to import all of them.
4.1.6 There is also a local LPCXpresso examples directory.
This is located at
C:\nxp\lpcxpresso\lpcxpresso\examples
4.2 Debugging/running 'blinky' or another project on
your LPCXpresso board
In LPCXpresso, when you start to debug, your program will
automatically download to the target and be programmed
into flash memory. So before debugging you connect LPCXpresso
development board to your PC and install it . Its very
simple, plug one end of the USB cable to PC USB-terminal
and other end of the USB cable to the LPCXpresso board.
Then open project blinky, click on the folder src and
open the c file 'blinky_main.c'
To start debugging on your target, simply highlight the
project in the Project Explorer and then in the Quick-start
Panel select 'Debug 'Project-name' [Debug].
After debugging, debug toolbar will come automatically
as shown in bellow diagram.
You are then presented with the debug view and toolbar
and have run control over the
code running on your target. The debug toolbar will pop
up above the code window.
After debugging press RUN button in debug toolbar, and
stop the debugger .Then you can observe LED blinking in
LPCdevelopment board
Sample programs1: blinking onboard LED
.
#include "driver_config.h"
#include "target_config.h"
#include "gpio.h"
int main (void)
{
int a;
GPIOInit();/* initialize GPIO (sets up clock*/
while(1) //Infinite loop
{ GPIOSetDir( LED_PORT, LED_BIT, 1 ); / * Set LED port
line to output */
for(a=0;a<1000000;a++);//delay
GPIOSetDir( LED_PORT, LED_BIT, 0 ); /* Turn LED on */
for(a=0;a<1000000;a++);//delay
}
}
Many such sample programs available in the IDE for you
to run.
Another sample program is explained in the next module.
