I2C Serial Decode
After completing the setup of I2C signal and trigger, we will decode I2C signals as follows:
1.
Press
Shift
and
→
Decode
. Select one of the options from the
Decode1

and set the number of lines by
Universal Knob
. The range of the lines is 1 to 7.
When a packet of data is long, not all decoded data are displayed. Turn on the
Long Data

display the complete data.
Users can export the result list of the package to a USB storage device in csv format.
Saving the data (*.csv) is similar to the operation of setup files; see the section "External save
and recall" for details.
5.

to turn on or off the decoding limit prompt. When the decoding frame number
reaches the maximum, it will give an alert: "Decoding to maximum frame number limitation!"
Interpreting I2C Decode
Decode Result Frames:
l
The address values are displayed at the beginning of a frame. The write address is displayed in
green, and the read address in yellow.
l
W/R bit is represented by (W) and (R), following the address value.
l
The data value is displayed in white.
l
"~A" after a data or address bits indicates no acknowledgement. For example, DB~A.
l
Indicates there is not enough space on the display to show the complete content of a frame,
and some content is hidden.

Decode Result Lists:
l
Time — the horizontal displacement between current frame and trigger position.
l
Address — the address of a frame.
