This code base exposes the C SDK by ADInstruments to Matlab.
General parts include:
- sdk class/package (see adi.sdk) - this is the Matlab code that directly interfaces with the mex code
- sdk_mex (see +adi/private directory) - this is the actual mex code which calls the ADInstruments dll
Note, I've also written a similar, slightly less polished version for Python. https://github.com/JimHokanson/adinstruments_sdk_python
LabChart provides functionality for exporting data to a '.mat' file, although I have yet to get it to work. I also prefer not having files that are simply copies of an original file but in a different format. This code allows reading data directly from LabChart data files.
- adi.readFile : Reads a file
- adi.convert : Converts the a given file to another format (e.g. from .adicht to .mat)
Like most of my more recent readers, the raw channel data are not returned unless specifically requested. Instead a lightweight (low memory) handle is returned with relevant meta data and the raw channel data can be requested via subsequent method calls.
f = adi.readFile;
pres_chan = f.getChannelByName('pressure');
raw_pres_data = pres_chan.getData(1); %Get data from the first recordAt some point a function could be written that reads everything and reads it into a structure but this is really really low priority for me.
To read these files on a Mac first requires converting the 'adicht' format into a 'mat' format. Unfortunately, the way in which these files needs to be created leaves the mat file looking a bit ugly. Once however it is in the 'mat' format, it can be read via the code in the same way that the original 'adicht' file could.
f = adi.readFile('/Users/Jim/Work/example_file.mat');I've fully implemented the reading portion. I've started the writing portion but I haven't finished it. I have no plans to finish the writing portion at this point in time.
Requires 64bit Matlab on Windows. 32bit Matlab could be supported but some of the mex code would need to be rewritten.
To install the package ('+adi') needs to be on the Matlab path. Sub-folders of the package should not be added to the path.
