24 I2C/SPI Triggering and Serial Decode

• Unknown bus values (undefined or error conditions) are drawn in red.

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. You can use the [Navigate] key and controls to navigate

through the marked rows.

1 With I2C selected as the serial decode mode, press [Search].
