CAN BUS ANALYZER USER'S GUIDE
Chapter 1. Introduction
1.1 INTRODUCTION
The CAN Bus Analyzer tool is intended to be a simple-to-use, low-cost CAN Bus monitor, which can be used to develop and debug a high-speed CAN network. The tool features a broad range of functions, which allow it to be used across various market segments, including automotive, marine, industrial and medical. The CAN Bus Analyzer tool supports CAN 2.0b and ISO 11898-2 (high-speed CAN with transmission rates of up to 1 Mbit/s). The tool can be connected to the CAN network using the DB9 connector or through a screw terminal interface. The CAN Bus Analyzer has the standard functionality expected in an industry tool, such as trace and transmit windows. All of these features make it a very versatile tool, allowing fast and simple debugging in any high-speed CAN network. The chapter contains the following information: · Can Bus Analyzer Kit Contents · Overview of the CAN Bus Analyzer · CAN Bus Analyzer Hardware Features · CAN Bus Analyzer Software
1.2 CAN BUS ANALYZER KIT CONTENTS
1. CAN Bus Analyzer Hardware 2. CAN Bus Analyzer Software 3. CAN Bus Analyzer software CD, which includes three components:
· Firmware for the PIC18F2550 (Hex File) · Firmware for the PIC18F2680 (Hex File) · The CAN Bus Analyzer PC Graphical User Interface (GUI) 4. USB mini-cable to connect the CAN Bus Analyzer to the PC
1.3 OVERVIEW OF THE CAN BUS ANALYZER
The CAN Bus Analyzer provides similar features available in a high-end CAN network analyzer tool at a fraction of the cost. The CAN Bus Analyzer tool can be used to monitor and debug a CAN network with an easy-to-use Graphical User Interface. The tool allows the user to view and log received and transmitted messages from the CAN Bus. The user is also able to transmit single or periodic CAN messages onto a CAN Bus, which is useful during development or testing of a CAN network. Using this CAN Bus Analyzer tool has many advantages over the traditional debugging methods embedded engineers typically rely on. For example, the tool trace window will show the user the received and transmitted CAN messages in an easy to read format (ID, DLC, data bytes and timestamp).

Chapter 2. Installation
2.1 INTRODUCTION
The following chapter describes the procedures for installing the CAN Bus Analyzer hardware and software. This chapter contains the following information: · Software Installation · Hardware Installation
2.2 SOFTWARE INSTALLATION
2.2.1 Installing the GUI
Install .NET Framework Version 3.5 before installing the CAN Bus Analyzer. 1. Run "CANAnalyzer_verXYZ.exe", where "XYZ" is the version number of the
software. By default, this will install the files to: C:\Program Files\ Microchip Technology Inc\CANAnalyzer_verXYZ. 2. Run the setup.exe from folder: C:\Program Files\Microchip Technology Inc\CANAnalyzer_verXYZ\GUI. 3. The setup will create a shortcut in the Programs menu under "Microchip Technology Inc" as Microchip CAN Tool ver XYZ. 4. If the CAN Bus Analyzer PC software is being upgraded to a newer version, the firmware should be updated to match the revision level of the PC software. When updating the firmware, ensure that the Hex files are programmed into their respective PIC18F microcontrollers on the CAN Bus Analyzer hardware.
2.2.2 Upgrading the Firmware
If upgrading the firmware in the CAN Bus Analyzer, the user will need to import the Hex files into MBLAB® IDE and program the PIC® MCUs. When programming the PIC18F2680, the user may power the CAN Bus Analyzer by an external power supply or by the mini-USB cable. When programming the PIC18F550, the user needs to power the CAN Bus Analyzer by an external power supply. Additionally, when programming Hex files into PIC MCUs, it is recommended to check the firmware version from the GUI. This can be done by clicking on the Help>About menu option.

3.2 TRACE FEATURE
There are two types of Trace windows: Fixed and Rolling. To activate either Trace window, select the option from the main Tools menu.
FIGURE 3-2:
FIXED TRACE WINDOW
FIGURE 3-3:
ROLLING TRACE WINDOW
The Trace window displays the CAN Bus traffic in a readable form. This window will list the ID (Extended is signified with a preceding `x' or Standard), DLC, DATA Bytes, the Timestamp and the time difference from the last CAN Bus message on the bus. The Rolling Trace window will show the CAN messages sequentially as they appear on the CAN Bus. The time delta between messages will be based on the last received message, regardless of THE CAN ID.
The Fixed Trace window will show the CAN messages in a fixed position on the Trace window. The message will still be updated, but the time delta between messages will be based on the previous message with the same CAN ID.

3.3 TRANSMIT FEATURE
To activate the Transmit window, select "TRANSMIT" from the main Tools menu.
FIGURE 3-4:
TRANSMIT WINDOW
The Transmit window allows the user to interact with other nodes on the CAN Bus by transmitting messages. The user is able to enter any ID (Extended or Standard), DLC or DATA bytes combination for single message transmittal. The Transmit window also allows the user to transmit a maximum of nine separate and unique messages, either periodically, or periodically with a limited "Repeat" mode. When using the limited Repeat mode, the message will be sent out at the periodic rate for a number of "repeat" times.
3.3.1 Steps to Transmit a Single-Shot Message
1. Populate the CAN message fields, which include the ID, DLC and DATA. 2. Populate the Periodic and Repeat fields with "0". 3. Click on the Send button for that row.
3.3.2 Steps to Transmit a Periodic Message
1. Populate the CAN message fields, which include the ID, DLC and DATA. 2. Populate the Periodic field (50 ms to 5000 ms). 3. Populate the Repeat field with "0" (which translates to "repeat forever"). 4. Click on the Send button for that row.
3.3.3 Steps to Transmit a Periodic Message with Limited Repeats
1. Populate the CAN message fields, which include the ID, DLC and DATA. 2. Populate the Periodic field (50 ms to 5000 ms). 3. Populate the Repeat field (with a value from 1 to 10). 4. Click on the Send button for that row.

3.4 HARDWARE SETUP FEATURE
To activate the Hardware Setup window, select "HARDWARE SETUP" from the main Tools menu.
FIGURE 3-5:
HARDWARE SETUP WINDOW
The Hardware Setup window allows the user to set up the CAN Bus Analyzer for communication on the CAN Bus. This feature also gives the user the ability to quickly test the hardware on the CAN Bus Analyzer.
To set up the tool to communicate on the CAN Bus:
1. Select the CAN bit rate from the drop-down combo box. 2. Click the Set button. Confirm that the bit rate has changed by viewing the bit rate
setting on the bottom of the main CAN Bus Analyzer window. 3. If the CAN Bus needs the termination resistor active, then turn it on by clicking
the Turn On button for the Bus Termination.
Test the CAN Bus Analyzer hardware:
1. Ensure that the CAN Bus Analyzer is connected. You can confirm this by viewing the tool connection status on the status strip on the bottom of the main CAN Bus Analyzer window.
2. To confirm that the communication is working between the USB PIC® MCU and the CAN PIC MCU, click on the Help->About main menu option to view the version numbers of the firmware loaded into each PIC MCU.
