DEMO9S08LG32—Quick Start Guide
Introduction
DEMO9S08LG32 is a cost-effective board
targeting quick microcontroller evaluation.
The MC9S08LG32 device is a 5V Freescale
microcontroller with an integrated liquid
crystal display (LCD) driver for automotive
and industrial applications.
DEMO9S08LG32 contains an on-board
display that allows developers to explore
software development using the integrated
LCD driver.
MC9S08LG32 is available in three pin
packages: 48-pin, 64-pin and 80-pin
LQFP, and two temperature ranges:
(-40°C to +85°C) for industrial applications
and (-40°C to +105°C) for automotive
applications. This quick start guide is
designed to provide step-by-step guidelines
to get you ready to develop your applications
using the MC9S08LG32
within minutes.

Step-by-Step Installation Instructions
Install CodeWarrior™ 6.2
for microcontrollers and
CodeWarrior v.6.2 Service
Pack for MC9S08LG32
Insert the Getting Started CD from
DEMO9S08LG32 kit into the CDROM drive
on your computer to install CodeWarrior.
This provides the driver files for built-in
debug support. The CodeWarrior v.6.2
Service Pack for MC9S08LG32 will
install the appropriate support files for
MC9S08LG32 to the existing CodeWarrior
installation. CodeWarrior installation is a
one-time required step before connecting
the board to your computer.
From the CD home page, click on Install
CodeWarrior. This will initiate the Code
Warrior install. After the install is complete,
return to the CD home page and click
on Install CodeWarrior Service Pack for
MC9S08LG32.
STEP
1
In this quick start guide, you will learn
how to set up the board and run the
default demo code.
Additional labs are available for the
LCD lab software. Please take a look
at the DEMO9S08LG32 lab document
included in the Training section of
the CD to learn more about the key
benefits that LG32 provides to your
applications.

Verify the default jumper positions on the board
All jumpers 2–88 shunted for LCD applications
USER 1 and 2 jumpers 1–8 connected
ADC jumper VDDA connected
Connected for buzzer application
MCU_EN and AGND jumpers connected
Connected to FIX
Connected to VB for power through USB, or connected to VR1 to power
through external supply
STEP
2

Install example software and
program the demo board
The CD provided in the demo board kit
contains example software. Insert the CD
into your computer.
From the main menu select
“Documentation.”
At the bottom of the screen, left click on
“LG Demo Board Software.”
This will open the folder that contains the
example software.
Right click on the DEMO_LG32 folder and
select “Copy.” Then, paste this folder onto
your computer’s desktop for easy access.
Next, Start CodeWarrior by selecting it from
the Windows Start menu.
From the CodeWarrior main menu, choose
“File > Open” and choose the DEMO_
LG.mcp that is found in the DEMO_LG
directory. This is the example software you
copied from CD.
Click “Open.” The Project window will open.
In the Code Warrior window:
Click Make
Click Debug
STEP
4
Connect the USB cable
between the PC and the
USB debugger connector
Operating system will recognize your
board as new hardware and will prompt
you to install the USB drivers. Choose
recommended option to install the software
automatically. USB drivers for your board
were pre-loaded in CodeWarrior installation.

DEMO9S08LG32—Quick Start Guide
When the debugger is launched:
From the connection manager click
“Connect (Reset).”
From Erase and Program Flash menu, click
“Yes” to allow the debugger to mass erase
the microcontroller’s on-chip memory and
program it with the new application.

The flash programming status window
(shown below) will appear.
Click Run
When CodeWarrior makes the connection,
the integrated debugger circuit provides
power to the MCU if PWR_SEL is
connected as VB, thus enabling the
application to run.

Use combination of KEY1 to KEY8 to see the various
functionalities of the LG32 demo in accordance with the
table below
DEMO LG32 Software Description
In the demo software, KEY1 is used to rotate between all the modes explained above and
other KEYs (KEY2, KEY3, KEY6, KEY7, KEY8) are used to select various demonstrations
under each mode (refer to table above).
Demo LG32 software exercises the following block functionalities:

displaying alphanumeric strings on digit segments, special characters, alternate string
mode, blinking and contrast control.
For LCD contrast control, connect a 12V supply to the barrel connector and change the
connector to VR1 and to RV1. The CONTRAST Pot should be used
to view the effect of contrast control.

• TPMBlock:InthePWMdemo,the
software uses PWM functionality of this
block to operate LEDs with different
frequencies.
• ADCBlock:DemoalsoexercisesADC
functionality in the Voltmeter and Driver
Info demonstration. For this the jumper
PTH0 should be connected and
removed after use.
Voltmeter displays the digital value of
measured analog voltage on the LCD.
Driver Information demo consists
of simulation of the number of
kilometers left as per the fuel
quantity left. In Driver Information
demo, fuel quantity left is controlled
by ADC input, where if number of
kilometers left is less than 50, then
LCD starts blinking to show the
criticality of the indication.
Use the ADC port to see the ADC
functionality.
