The Software Templates
4.4.1
Bus Status Window
This window, labeled “MCP2515 CAN Controller”, provides several pieces of
information about the status of the bus, including nominal bus loading, status of node
(on or off the bus) and bus bit rate. The tabs at the top of the window toggle between
the Bus Statistics and Bus Parameters view.
In the Bus Statistics view, the bus loading, bus parameters and bus status may be
viewed. The bus loading shows the nominal load on the CAN bus as a percentage and
as a number, as well as the total number of messages sent and received. The bus
parameters simply reflect the parameters that were set in the Bus Parameters view
(i.e., bit rate, number of TQ, bit segment lengths and the location of the sample point).
The bus status shows the mode of operation, error states and gives the user the ability
to switch modes of operation between Normal and Configuration.
The Bus Parameters view allows configuration of the bus rate, the sample point, the
synchronizing jump width (SJW) and switching between Normal and Listen-Only
modes of operation.
