SETTING UP THE BASIC TEMPLATE EVALUATION MODE
Chapter 2. MCP250XX Basic View Tutorial
This tutorial discusses the evaluation portion of the kit, details the demonstration soft-
ware (Basic template), CAN system (PC Node and Node B) and covers the steps
required to successfully run the demonstration network.
The user defaults for Node B are preprogrammed at the factory. Therefore, no user
default programming is necessary. No discussion of programming user defaults will
take place in this chapter, as this is detailed in Chapter 4. “Programming the
MCP250XX User Defaults”.
This chapter covers the following topics:
• Setting up Evaluation mode
• Establishing communications
• Explaining the CAN messages
The MCP250XX Development Kit’s “Basic” template contains the following major
elements:
1. Menu Bar (Figure 2-1) – The layout is typical of most Windows menu bars.
