After logging is complete, you can open MAT-files in MATLAB®, and use them for further analysis. Since the data points are stored in MAT files, you can directly open the files in MATLAB without converting them into any other format.
In C2000, remove the SD Card from the board, connect it to a computer and read the .mat files from the explorer.
The files are named as
The name of your Simulink® model is
runnumber is the number of times
the model is run.
runnumber starts with
1 and is
incremented by one for every successive run.
indexnumber is the
MAT-file number in a run.
indexnumber starts with
1 and is incremented by one for every new file that is created in
the same run.
Suppose that the name of the model is
sdcard. In the first run,
sdcard_1_1.mat file and starts logging data in this file. After
the logging in the first file is completed, Simulink creates
sdcard_1_2.mat file and continues
logging data in this file. Likewise, the logging continues in multiple MAT-files until
the Simulation stop time is elapsed. If the same model is run
again, the new files are named as
sdcard_2_2.mat, and so on.
Data loss occurs when:
The total file size exceeds the available SD card storage capacity.
The signal logging rate is faster than the SD card writing speed.
