Interpreting I2C Decode
 Active 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 the horizontal scale should be expanded (and run again) to see
decode.
