MCP2515 Development Kit User’s Guide

BASIC TEMPLATE
The Basic template is a high-level tool that focuses on CAN bus traffic. The user only
has high-level control of the MCP2515 (i.e., no direct register control) that includes:
?
?
?
?
?
Configuring the bus rate
Changing modes of operation (Configuration and Normal)
Configuring a transmit register (the register number is predefined)
Transmitting messages
Resetting the MCP2515
Other functions of the Basic template include receiving messages, saving transmitted
messages, starting timed transmissions and observing the bus loading. Details of these
functions can be found later in this section under the details of the individual windows.
Note:
Node 0 is configured to receive ALL messages by default while in the
Basic template. The user has the option to maintain MCP2515 configura-
tions when switching templates by selecting Options > MCP2515… and
deselecting the Reset MCP2515 on Opening box. Keep in mind that
deselecting this box may create unforeseen problems if the MCP2515
was not previously configured properly.
This template would typically be used as a simple bus monitor for evaluating the
MCP2515 on a CAN bus or in assisting development by monitoring how node 1 is
operating.
