Microchip Technology LIN Serial Analyzer User’s Guide

LIN Serial Analyzer

User’s Guide Rev2.0

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 A ct. If such acts allow unauthorized access to your software or other copyrighted work, you may have a right to sue for relief under that Act.

LIN Serial Analyzer User’s Guide Rev2.0

NOTES:

Chapter 1. LIN Serial Analyser Overview

1.1 INTRODUCTION

The LIN Serial Analyser development system enables a Personal Computer (PC) to communicate with a LIN (Local Interface Network) bus. The PC program uses a graphical user interface to enter and display message frames occurring on the target bus. The LIN Serial Analyser connects to the system network using a three-position terminal block.

Chapter 2. “Getting Started” will guide you through installing the PC program, the Windows

1.2 HIGHLIGHTS

operating system drivers and setting up the hardware.

1.3 LIN SERIAL ANALYSER CONTENTS

The LIN Serial Analyser kit contains the following items:

• LIN Serial Analyser

• Mini-B USB Cable

• LIN Serial Analyser CD-ROM

1.4 LIN SERIAL ANALYSER DEVELOPMENT TOOL

The LIN Serial Analyser consists of several components, that together, make a network debug and analysis tool. The user interface program runs on Microsoft operating system compatible computers with a USB port.

The LIN Serial Analyser connects to the PC using a mini-B USB cable. The LIN Serial Analyser interfaces to the target network using a three-position, screw-type terminal block. Figure 1-1 illustrates the LIN Serial Analyser tool connected to a network.

1.5.1 Status LEDs

The Status LEDs indicate the status of the LIN Serial Analyser. An illuminated LED means:

• USB (green) – Power has been applied to the LIN Serial Analyser by the USB port.

• Busy (yellow) – The LIN Serial Analyser is communicating with the LIN network.

• LIN (blue) – The LIN Serial Analyser is connected to the target bus.

LIN Serial Analyser Overview

1.5.2 USB Port Connection

The USB port connection is a USB mini-B connector. Connect the LIN Serial Analyser to the PC using the cable supplied with the device.

1.5.3 Network Communication Connector

The communication connector connects to the target device using a three-position, screw clamp terminal block. The pin assignments, labeled on the top of the device, are:

• VBAT – Positive battery connection for voltage supplied by the vehicle

• LIN – Bidirectional data I/O

• GND – Common chassis, power and serial ground

1.5.4 Power Jack

The device us es a stan dard, 6.5 x 2.5 DC pow er plug. Th e center pi n is posit ive. Powe r can be supplied either through the power plug or the network connector as the two are internally connected.

1.6 LIN SERIAL ANALYSER SOFTWARE

1.6.1 User Interface Program

The LIN Serial Analyser PC program displays all of the board’s bus activity via the software’s Transaction window, displayed on the connected PC. This is useful for “sniffing” the bus and tracking message frames.

Chapter 3. “LIN Serial Analyser PC Program” explains the installation and operation of the program.

Network Connection

1.6.2 Firmware

The LIN Serial Analyser firmware is explained in Chapter 9. “PICkit™ Serial Analyzer Firmware” of the “PICkit™ Serial Analyzer User’s Guide” (DS51647).
