13.2.5 Search on decoded I²C data
Using the search functionality, you can find various events in the decoded data, the
same events which you also can trigger on. Before you can start the search, you have
to configure the bus correctly and acquire decoded data.
To search on decoded data, set the search "Source" to the serial bus that is configured
for the protocol to be analyzed.
See also Chapter 11, "Search functions", on page 448.
13.2.5.1 I²C search setup
Access: [Protocol] > "Shortcuts" tab > "Setup search"
Select search types
Enable the events to be searched for. Unlike triggering, where you can trigger only on
one defined event, you can search for various different events in one search.
"Start"
Searches for the start of the message. The start condition is a falling
edge on SDA while SCL is high. The event is the falling edge of the
SDA line.
You can change the SDA and SCL lines here if necessary.
