MATLAB: How do you convert a DAT file to a text file

dat conversiontext file

can you attach your binary file?

Best Answer

Yes, most likely you can convert the file - if you can examine the internal structure. Look into the docs of the program, which creates these DAT files. Either you find a clear description there and can create a file to import the binary data in Matlab. Or the program allows to import such a DAT file and export it as text file.

Creating a Matlab function to import the binary DAT files is usually not too complicated, but not trivial also. Without knowing the specific definition of the format, it is impossible to guess, how the import function must be written.

Okay, binary data. :( Do you know what the file is supposed to contain? What is created on a Intel x86 machine (that is, is the floating point format likely to be compatible with your current machine)? Unless you know something about the data you are reading in, you're flying blind.

I might be tempted to try:

 f = fopen('foo.dat, 'rb');
 D = fread(f, inf, '*float');  % Try '*double' too
 fclose(f);
 plot(D);

Does a signal eventually emerge in the plot? If there is a header following by a stream of vector data, you might see a burst of noise (the header) followed by the data.

Beyond this, I don't have a lot of ideas, sorry.

MATLAB: Using “Raspbian Buster” OS, why do I get build errors related to I2C when creating a RASPI object, or building a model with I2C blocks

With the new version of Raspbian OS, “Raspbian Buster”, some header files of “i2c-dev” library got re-organized and our I2C source code is not compatible with the same. MATLAB IO server needs to be updated to fix this issue.

As a result, users working with this newer OS image and running OS customization from our Raspberry Pi Support Package during Hardware Setup will meet this build error while trying to run the command “r=raspi()”, or when using the I2C block from Simulink and trying to build the model.

MATLAB releases R2017b, R2018a, R2018b, and R2019a will be affected by this error as OS Customization support has been available from R2017b.

1) To fix error for MATLAB command “r = raspi()”:

Enter below command at the MATLAB prompt and edit the source code as shown in the attached screenshot:

>> edit(fullfile(raspi.internal.getRaspiRoot,'server','I2C.c'))

2) To fix the error in Simulink for I2C blocks:

Enter below command at the MATLAB prompt and edit the source code as shown in attached screenshot:

>>edit(fullfile(codertarget.raspi.internal.getSpPkgRootDir,'src','MW_I2C.c'))
