Make sure that:

–
The correct "Protocol" is selected.
–
The data sources of the serial bus are channel signals.
●
In the "Trigger" > "Setup" tab:
–
The "Trigger on" = "Single event"
–
The trigger "Source" = "Serial bus".
–
The correct "Serial bus" is selected.
Serial bus
Selects the serial bus to be triggered on. Make sure to select the correct bus before
you enter the settings.
To trigger on a serial bus, the signals sources must be channel signals. If the data or
clock source is a math or reference waveform, you cannot trigger on that bus.
Remote command:
Trigger type
Selects the trigger type for I²C analysis.
Some trigger types have additional settings that can be defined. In this case, the
"Define trigger details" button appears next to the "Type" function. Open it for a
detailed definition of the trigger conditions.
Remote command:
Start ← Trigger type
Sets the trigger to the start of the message. The start condition is a falling edge on
SDA while SCL is high. The trigger instant is the falling edge of the SDA line.
You can change the SDA and SCL lines here if necessary.
