Interpreting I2S Decode
• Angled waveforms show an active bus (inside a packet/frame).
• Mid-level blue lines show an idle bus.
• In the decoded data:
• Right channel data values appear in green along with the "R:" characters.
• Left channel data values appear in white along with the "L:" characters.
• Decoded text is truncated at the end of the associated frame when there is
insufficient space within frame boundaries.
• Pink 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.
• Aliased bus values (undersampled or indeterminate) are drawn in pink.
• Unknown bus values (undefined or error conditions) are drawn in red.
