TOOLS FUNCTIONS
This sections lists the commands on the Tools pull-down menu.
3.6.1
Selecting Tools>Debug Mode enables the user to debug bus or slave operational
issues.
One function forces a user-supplied checksum to be appended to a master message
to check a slave for proper error handling. In this mode, the generation of identifier
parity bits is inhibited and the identifier byte is transmitted without modification.
3.6.2
The current implementation of the master task cannot refer to a LIN descriptor file, so
there is no way to determine the length of any received message. To calculate an
appropriate time-out value, multiply the length of an eight-byte frame times 140% of the
bit rate.
This value can be overridden by entering a fixed time-out value in the COM Setup
window, described in Section 3.5.1 “Setup COM port”.
3.6.3
This function clears the Transaction window and resets the time-stamp.
3.6.4
This opens a window to display all messages received through the Transaction window
but are sorted by ID number. The window is ‘live’ and shows current bus traffic. New
message frames received will overwrite previous data. This is useful in monitoring con-
stanly changes data.
3.6.5
This option selects the Transmit Only mode. No received messages are displayed in
the Transaction window.
3.6.6
This option selects the Listen Only mode. Only non-duplicated messages are displayed
in the Transaction window.
When “snooping” bus message frames, this prevents the Transaction window from
becoming cluttered with repeated frames.
3.6.7
This function selects the Display All mode. All messages seen on the bus are
displayed.
This mode is best used with the data logging feature to capture all bus traffic for later
analysis.
