Interpreting IIC Decode
Angled waveforms show an active bus (inside a packet/frame).
Mid- level blue lines show an idle bus.
In the decoded hexadecimal data:
Address values appear at the start of a frame.
Write addresses appear in dark- green along with the "W" character.
Read addresses appear in yellow along with the "R" character.
Data values appear in white.
"A" indicates Ack (low), "~A" indicates No Ack (high).
Decoded text is truncated at the end of the associated frame when there is
insufficient space within frame boundaries.
Blue vertical bars indicate you need to expand the horizontal scale (and run again) to
see decode.
Red dots in the decode line indicate that more data can be displayed. Scroll or
expand the horizontal scale to view the data.
Interpreting IIC Lister Data
In addition to the standard Time column, the IIC Lister contains these columns:
NO— frame number from left to right
Address — colored blue for writes, yellow for reads.
R/W—yellow R for read, dark green W for write and black X for miss..
Data — data bytes.
