MatLab or LabVIEW drivers?

[robert.ghilduta]

Hi Yoshimi,

There's more up to date code in https://github.com/Nuand/bladeRF-matlab . The Github branch is where all of the active development is happening.

Antti,
I think compile.m should work on Mac as well. Maybe some of the paths are different?
What sort of error messages are you seeing?

Hi, this is what i get:

Hello,
I'm trying to compile the Matlab interface using source codes from git and tar file on Ubuntu 14.04.
http://nuand.com/downloads/matlab.tar.gz
https://github.com/Nuand/bladeRF-matlab

I modified only the following.
The version of gcc installed on Ubuntu 14.04 is 4.8, but Matlab supports only gcc 4.7, so I installed gcc 4.7.
The compile.m file we can get from git seems to support only Windows OS, so I used compile.m from the tar file as well even when compiling files from git.

Both of them caused some errors in the middle of compiling.
Do these errors mean mismatch of the version between the Matlab interface and the driver of bladeRF?
Would you give me some advice?

What this looks like is that the MATLAB driver has suffered a bit of rot in terms of the libbladeRF API and is trying to use functions which don't exist anymore.

I have just posted the issue to github to mark it down that we need to address this issue.

Currently we're on a push to get a stable library built up with a stable API so this won't happen again, so pull requests are welcome when it comes to modernizing the MATLAB driver for the current/more stable API. Also note that using the synchronous interface is probably the better way to get samples in/out of the device.

Sorry for the inconvenience.

Thank you for your reply. Sorry my reply is late.
I suppose you may be adapting the matlab Interface to the latest driver.
As far as I can see, the current matlab interface does not include any functions for transmitting.
I'd like the matlab interface by which we can transmit and receive simultaneously. Are you currently making such an interface?
If the next version of matlab interface that can transmit will be released soon, I'd like to use it.
However, I'm trying to make a matlab interface using the following sample codes which are written in C in case it will take a little more time to be released.
https://github.com/Nuand/bladeRF/tree/0 ... t_sync/src

If some threads for transmitting and receiving process can be spawned by a mex-file like the sample codes, I think I can transmit and receive at the same time without consideration on the timing of transmitting or receiving at the invoker side, i.e. m-file.
Is it possible to make such a mex-file? Would you give me any advice if you already have some experience?
