MCP2515 CAN BUS MONITOR DEMO BOARD USER’S GUIDE Chapter 2. Installation and Operation 2.1 INTRODUCTION The MCP2515 CAN Bus Monitor Demo Board kit demonstrates the MCP2515 Stand-Alone CAN Controller interfacing to a CAN bus. The MCP2515 CAN Bus Monitor Demo Board kit consists of two identical boards which, when connected together, create a small, 2-node CAN bus. This bus can be interfaced to a PC by connecting one of the two boards to the PC (USB) and running the custom software.
MCP2515 CAN Bus Monitor Demo Board User’s Guide 2.3 GETTING STARTED The MCP2515 CAN Bus Monitor Demo Board is a fully functional, assembled, and tested kit used to demonstrate the MCP2515 in a CAN bus environment. The following describes the basic setup and operation. See Figure 2-1 and Figure 2-2 for a simplified functional diagram and block diagram. Basic Setup: 1. Connect the two boards together using the supplied ribbon cable 2. Connect the USB cable to PC 3. Start the bus monitor software.

MCP2515 CAN Bus Monitor Demo Board User’s Guide 2.4 FUNCTIONAL OPERATION The MCP2515 CAN Bus Monitor Demo Board is basically a USB-to-CAN board which provides visual feedback of Controller Area Network operation. The two boards included in the kit can be used together to create a 2-node CAN bus. The function of the board is determined by how it is powered. 2.4.
Installation and Operation 2.5 SOFTWARE OPERATION The software consists of five (5) main windows that are selected by tabs: 1. Bus Statistics Window: Shows the status of the bus, including on/off the bus, bus loading, number of transmitted and receive messages, and bit timing settings status. See Figure 2-4 2. Bus Parameters Window: Is used to set basic bit timing. The bus speeds are limited to the values in the pull-down box. To set custom bit timing, refer to the MCP2515 Configuration Window.
