State Logs
Events can be logged in the software by checking the
“Auto Poll” option in the Preferences menu. These logs can
be useful in debugging and in checking the timing of various
operations. Each log message has the timestamp (with
100 ms resolution). To stop logging, click the “Auto Poll”
option in the Preferences menu.
An example of a Type−C attach and the PD
communication flow is shown below.
To support debug efforts, the “Set State” button can be
used to force a specific state machine state. The state can be
selected in the pull down menu to the left of the “Set State”
button.
The screens can be cleared with the “Clear State Log” and
“Clear PD State Log” buttons to the right of each window.
Either Type−C State log or Policy Engine State log can be
saved to a text log file using the “Save TC Log” and/or “Save
PD log” buttons.
