Chapter 3. MCP250XX Register View Tutorial
A few topics covered in this chapter were also covered in the last chapter detailing the
Basic template tutorial. To avoid duplication, the appropriate sections of Chapter 2
“MCP250XX Basic View Tutorial” will be referenced.
This chapter details the demonstration software (Register template) and CAN system
(PC Node and Node B). It also covers the steps required to successfully communicate
with the MCP250XX while in the Register template.
This chapter covers the following topics:
• Setting up the Evaluation Mode
• Establishing Communications
• Explaining the Windows
The MCP250XX Development Kit’s “Register” template contains the following major
elements that will be discussed, in detail, later in this chapter:
1. The Menu Bar, PC Node Bit Timing and Mode and Board Status windows are
