Message Trace

Message Trace allows you to view live CAN bus traffic. This is one of the most important Views available in CanKing and offers a wide range  of features. Messages can be arranged by time received, ID, flags, or DLC. The delta times of messages are available, with delta being the time from the last message with the same CAN identifier to the most recent. The window can be further filtered by only showing a trace of a specific channel in the measurement by clicking the Channel drop-down menu. Similarly, the trace can filter just the received or transmitted messages.

Besides the ability to pause and clear the message trace, you can click the Fixed Position button to lock messages by ID. When in Fixed Position mode with a DBC file in the measurement, clicking the drop-down arrow will show further information based on the database.

The trace can be filtered by protocol from the Protocol dropdown menu. Additional detailed layouts are available via the Interpreter dropdown menu where interpreters of J1939 and LIN message info reside though a J1939 DBC file will be necessary for displaying signal values.  For easier viewing of longer data frames such as CAN FD applications, the number of bytes that appear per row can be adjusted in the Bytes Per Row dropdown.
