IIC decoding interpretation:
1. Decoded data is displayed in hexadecimal;
2. The display colors of "address" and "data" are purple;"W" means write operation, "R"
means read operation, "D" means decode data, "~A" means no confirmation bit;
3. When "?"or"please adjust the time base"appears ,the time base needs to be adjusted to
get the decoded result.
6.6.Protocol Decoding
Protocol analysis can be used by users to discover errors, debug hardware and
accelerate development easily, DPO6000/MPO6000 series oscilloscopes provide 5 kinds
of common protocol decoding,including UART
、
LIN,CAN,I2C and SPI.
Note
:Only when the user correctly sets protocol trigger setting parameters can get the
correct decoding result.
6.6.1.Decoding mode
The decoding function is only available at the time of protocol trigger. Turn on the decoder
switch, and the magenta parallel decoder cursor appears on the left side of the
oscilloscope [default is at the bottom of the screen]. By selecting the label location menu,
the user can change the label position through V0 to make the decoded position
waveform has a better display position,so it’s convenient for the user to analyze the
decoded data.
6.6.2.Table mode
The table function is only available at the time of protocol trigger. When the form mode is
turned on, the oscilloscope will not display the acquisition data of the waveform, only
display the correct protocol decoded data. The decoded data will be transmitted to the
screen in real time, and the form mode can decode data continuously. When an
oscilloscope runs in table mode, only the F1,F2,F3,RUN/Stop softkey is available.Other
keys cannot be used. If the users need to set other parameters of the serial port, they
need to exit the table mode. After users make a pause, the decoded data can be exported
for analysis.
