User’s Guide

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 Digital Millennium Copyright Act. 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.

Information contained in this publication regarding device applications and the like is provided only for your convenience and may be superseded by updates. It is your responsibility to ensure that your application meets with your specifications.

Chapter 1. Product Overview

1.1 INTRODUCTION

This chapter provides an overview of the MCP2515 CAN Bus Monitor Demo Board and covers the following topics:

• What is the MCP2515 CAN Bus Monitor Demo Board?

• What the MCP2515 CAN Bus Monitor Demo Board kit includes

1.2 WHAT IS THE MCP2515 CAN BUS MONITOR DEMO BOARD?

The MCP2515 CAN Bus Monitor Demo Board kit contains two identical boards which can be connected together to create a simple two n ode Controller Area Network (CAN) bus, which can be controlled and/or monitored via the included PC interface. The board(s) can also be connected to an existing CAN bus.

Using the PC interface, users can configure the MCP2515 registers, send CAN messages, and receive CAN messages. CAN traf fic can be generated using a button on the board not connected to the PC.

There are also several headers (test points) so the MCP2515 pins can be monitored.

1.3 WHAT THE MCP2515 CAN BUS MONITOR DEMO BOARD KIT INCLUDES

The MCP2515 CAN Bus Monitor Demo Board Kit includes:

• Two MCP2515 CAN Bus Monitor Demo Board boards, 102-00108

• PIC18F4550 Firmware

• Connector cable to connect the two boards together

• Analog and Interface Products Demonstration Boards CD-ROM (DS21912)

- MCP2515 CAN Bus Monitor Demo Board User's Guide, DS51757)
