Note the following details of the code protection feature on Microchip devices:
• Microchip products meet the specification contained in their particular Microchip Data Sheet.
• Microchip believes that its family of products is one of the most secure families of its kind on the market today, when used in the
intended manner and under normal conditions.
• There are dishonest and possibly illegal methods used to breach the code protection feature. All of these methods, to our
knowledge, require using the Microchip products in a manner outside the operating specifications contained in Microchip’s Data
Sheets. Most likely, the person doing so is engaged in theft of intellectual property.
• Microchip is willing to work with the customer who is concerned about the integrity of their code.
• Neither Microchip nor any other semiconductor manufacturer can guarantee the security of their code. Code protection does not
mean that we are guaranteeing the product as “unbreakable.”
Code protection is constantly evolving. We at Microchip are committed to continuously improving the code protection features of our
products. Attempts to break Microchip’s code protection feature may be a violation of the Digit al Millennium Copyright Act. If suc h a c t s
allow unauthorized access to your software or other copyrighted work, you may have a right to sue for relief under that Act.

The PICkit™ Serial Analyzer development system enables a personal computer (PC)
to communicate with embedded development systems via serial protocols such as
2
I
C™, SPI, asynchronous and synchronous USART. The PC program uses a graphical
interface to enter data and commands to communicate to the target device. Data and
commands can be entered using basic or scripting commands. The PICkit™ Serial
Analyzer connects to the embedded development system using a 6-pin header.
The PICkit™ Serial Analyzer is a sophisticated and highly configurable device. Please
take a few moments to familiarize yourself with the hardware interface and PC program
by reading this user’s guide. Chapter 2. “Getting Started” will guide you through
installing the PC program and running a simple demonstration program on the 28-Pin

perform a power on routine:
• LEDs will flash in sequence DS1, DS2, DS3, DS4, DS3, DS2, and DS1 twice
• All LEDs will turn off
• All LEDs will turn on
• All LEDs will turn off
• LEDs will display in hexadecimal: A, D, C
• LEDs will display the top 4 bits of the ADC value read from potentiometer RP1

2.6 STARTING THE PICkit™ SERIAL ANALYZER PROGRAM
You can start the program by:
• Clicking on the desktop icon, or
• Navigating to Start>All Pr ograms>Microchip>PICkit Serial Analyzer
After a few moments, the program will start and display the main window as shown in
Figure 2-2.
If this is the first time you are running the program, the Configuration Wizard will auto-
matically run. Click on the Next button and accept the default settings for I

2.7 RUNNING THE 28-PIN DEMO I2C™ DEMONSTRATION PROGRAM
Select the 28-Pin Demo I2C demonstration by clicking on Demo Boards > 28 Pin Demo
I2C from the menu bar. The 28-Pin Demo I2C demonstration window will be displayed
as shown in Figure 2-3.
The Real-Time Clock (RTC) will be displayed first. Note the tabs to select between the
RTC, EEPROM and ADC demonstrations. The demonstration program will constantly
poll the 28-Pin Demo Board and display the contents of the real-time clock and the
ADC.
2.7.1 Real-Time Clock (RTC)
Clicking on the Real-Time Clock tab will display calendar and clock contents of the
real-time clock function running on the 28-Pin Demo Board. The 28-Pin Demo Board
has been programmed to emulate a stand-alone serial I
2
I
C commands are very similar to the commands used in these devices. The demonstration program will constantly poll the 28-Pin Demo Board and display the contents
of the real-time clock.
The Real-Time Clock window displays calendar and clock controls. Notice the date and
time when the 28-Pin Demo Board has first been powered on. The date and time start
at January 1, 2000 at midnight (12:00 AM).
The user can manually enter calendar and clock values and send the values to the
real-time clock by clicking on the Update RTC button. Or the user can click on the Set
RTC to System Time button to set the real-time clock to the date and time of the
computer.

2.7.2 Serial EEPROM (EEPROM)
Clicking on the EEPROM tab will display the 256 byte array of EEPROM memory as
shown in Figure 2-4. The 28-Pin Demo Board has been programmed to emulate a
stand-alone serial I
very similar to the commands used in these devices.
The Serial EEPROM tab displays the contents of a serial EEPROM implemented on
the 28-Pin Demo Board. When this tab is first displayed, the values are grayed out. This
means that the display does not match the contents of the emulated serial EEPROM.
Click on Read EE button and the program will read and display the contents of the
28-Pin Demo Board. Notice that the displayed values are now black.
Individual memory locations can be changed by clicking on the value and typing in a
new value in hexadecimal. Notice that the changed values will be displayed in red. This
means the value has changed but has not been written to the emulated serial
EEPROM. Click on the Write EE button and the values will be written. The color of the
value will turn to black indicating that the value has been written and the display
matches the contents of the emulated serial EEPROM.

Clicking on the ADC tab will show a meter gauge displaying the value of the ADC as
read from potentiometer RP1 as shown in Figure 2-5.
The meter gauge displays the Most Significant 8 bits of the 10-bit ADC internal to the

Chapter 3. PICkit™ Serial Analyzer PC Program
3.1 INTRODUCTION
This chapter covers the installation, starting and high level operations of the PICkit
Serial Analyzer program. Detailed information about the entering of data and commands for specific serial communications modes are given in the following chapters.
3.2 HIGHLIGHTS
This chapter discusses:
• Installing The PICkit Serial Analyzer Software
• Starting the Program
• Configuration Wizard
• Main Window
• Specific Communications Modes
3.3 INSTALLING THE PICkit™ SERIAL ANALYZER SOFTWARE
Insert the PICKit Serial Analyzer CD-ROM into the CD-ROM drive. In a few moments
the introductory screen should be displayed. Follow the directions on the screen to
install the PICkit Serial Analyzer software.
If the introductory screen does not appear, browse to the CD-ROM directory and select
the AutorunPro.exe program.
Note: The PICkit Serial Analyzer program requires the Microsoft
Framework Version 2.0.
3.4 STARTING THE PROGRAM
You can start the program by
• Clicking on the desktop icon, or
• Navigating to Start>All Pr ograms>Microchip>PICkit Serial Analyzer
After a few moments, the program will start and display the main window as shown in
Figure 3-1.

Advanced configuration can be done from the Configuration Window by selecting PIC-
kit Serial Analyzer > Configure Communications Mode from the menu bar.
As an example, Figure 3-2 through Figure 3-7 show how to configure for I
mode. Refer to the specific communications chapter for detailed information on the
Configuration Wizard for that communications mode.

The PICkit Serial Analyzer can power the target device from 0 to 5 V
total current limit of 100 mA (PICkit Serial Analyzer plus target device). The Configuration Wizard Page 4 of 4, as shown in Figure 3-6, allows you to choose between
powering the target device and selecting the specific target voltage.

CAUTION
Even though the voltage can be set as low as 0 VDC, it is up to the user to verify the
required operating voltage of the target device.
CAUTION
The USB port current limit is set to 100 mA. If the target plus PICkit Serial Analyzer
exceeds this current limit, the USB port will turn off. The target may be powered
externally if more power is required.
