CAN BUS ANALYZER USER’S GUIDE Chapter 3. Using the PC GUI Once the hardware is connected and the software is installed, open the PC GUI using the shortcut in the Programs Menu under “Microchip Technology Inc” labeled as Microchip CAN Tool ver XYZ. Figure 3-1 is a screen shot of the default view for the CAN BUS Analyzer. FIGURE 3-1: 3.1 CAN BUS ANALYZER DEFAULT VIEW GETTING STARTED WITH A QUICK SETUP The following are setup steps to quickly start transmitting and receiving on the CAN BUS.
CAN Bus Analyzer User’s Guide 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 an preceding 'x' or Standard), DLC, DATA Bytes, the Time stamp and the time difference from the last CAN BUS message on the BUS.
Using the PC GUI 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.
CAN Bus Analyzer User’s Guide 3.4 FUTURE FEATURE – GROUP TRANSMIT FEATURE To activate the Group Transmit window, select “GROUP TRANSMIT” from the main Tools menu. FIGURE 3-5: GROUP TRANSMIT WINDOW The Group Transmit window allows the user to interact with other nodes on the CAN BUS by transmitting messages. The user is able to transmit a limited group of messages in sequential order spaced out by user-defined timing in the Period field.
Using the PC GUI 3.5 FUTURE FEATURE –TRACE FILTER SETUP FEATURE To activate the Trace Filter Setup window, select “TRACE FILTER SETUP” from the main Tools menu. FIGURE 3-6: TRACE FILTER SETUP WINDOW The Trace Filter Setup window allows the user to filter the Trace window for only the required IDs the user wants to view. The trace filter can match the log file filter or it can contain a completely different set of IDs. Steps to setup the trace filter to match the log file filter 1.
CAN Bus Analyzer User’s Guide 3.6 LOG FILE SETUP FEATURE To activate the Log File Setup window select “LOG FILE SETUP” from the main Tools menu. FIGURE 3-7: LOG FILE SETUP WINDOW The Log File Setup window allows the user to setup a log file of the CAN BUS traffic. This feature helps gather more information when debugging design issues, by capturing the BUS traffic when an event occurs. Log File Setup also allows the user to setup a filter to either include or exclude user-defined IDs.
Using the PC GUI 3.7 HARDWARE SETUP FEATURE To activate the Hardware Setup window, select “HARDWARE SETUP” from the main Tools menu. FIGURE 3-8: HARDWARE SETUP WINDOW The HARDWARE SETUP window allows the user to setup 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 bitrate from the drop-down combo box. 2. Click the “Set” button.
CAN Bus Analyzer User’s Guide 3.8 FUTURE FEATURE – SAVING AND RETRIEVING THE TOOL CONFIGURATIONS 3.8.1 Saving Tool Configurations The CAN BUS Analyzer tool allows the user to save various configuration setups by the user in a particular session. The GUI will save the transmit window settings, log file settings, and screen positions of the various windows of the tool. By choosing “Save Configuration” under the File menu, the file is saved in a default Temp folder under the default name “config.ini”.
CAN BUS ANALYZER USER’S GUIDE Appendix A. Error Messages In this section, the various “pop-up” errors that are found in the GUI will be discussed in detail as to why they may occur, and the possible solutions for correcting the errors. TABLE A-1: ERROR MESSAGES Error Number Error Possible Solution 1.00.x Trouble reading the USB firmware version Unplug/plug the tool into the PC. Also make sure that the PIC18F2550 is programmed with the proper HEX file. 2.00.
CAN Bus Analyzer User’s Guide Error Number Error Possible Solution 4.10.x Enter DLC within the following range (0-8) 4.20.x Enter DATA within the following range Enter valid Data into the text field. The tool is expecting (0-FF) a hexidecimal value in the range of “0-FF”. 4.25.x Enter DATA within the following range Enter valid Data into the text field. The tool is expecting (0-255) a decimal value in the range of “0-255”. 4.30.
