Interpreting I2C Lister Data
In addition to the standard Time column, the I2C Lister contains these columns:
• Restart — indicated with an "X".
• Address — colored blue for writes, yellow for reads.
• Data — data bytes.
• Missing Ack — indicated by an "X", highlighted in red if an error.
Aliased data is highlighted in pink. When this happens, decrease the horizontal
time/div setting and run again.
Searching for I2C Data in the Lister
The oscilloscope's search capability lets you search for (and mark) certain types of
I2C data in the Lister (see
"Searching Lister Data" on page 121). Then, you can use
the navigation controls to navigate through the marked rows (see
"Navigating the
Time Base" on page 52).
The Search dialog box controls unique to the PN: I2C search type selection are:
• Search for — Selects the decode value to find:
• Restart — Finds when another start condition occurs before a stop condition.
• Address — Finds a packet with the specified address, ignoring the R/W bit.
