Is there any way to read realtime, live, data produced on a raspberry PI directly on Matlab ( don't using ThigSpeak)?
I.e. I'd like to read live Raspberry CPU temp in matlab without using ThingSpeak.
Any idea?
Thanks in advance

I'm not experienced with directly reading from raspberry Pi/arduino, but this link might help you out.

Hi Manash.
Thanks for you reply.
Actually I need to read a data that are produced from a runnig code on Raspberry PI.
Like CPU temp in this example:
I haven't nay serial device attached to my Raspberry Pi

Have you looked at the Raspberry Pi Support Package?

Hi Vinod.
Thanks for you reply.
Yes, I've read carefully all docs on Raspberry Pi Support Package but I don't know how create a "link" between Matlab and Raspberry so that , i.e., every value of the CPU's temp printed on Raspberry (and that I can view by means Putty) at the same time will be trasferred to Matlab.
I can do this via ThingSpeak but not directly from Raspberry PI to Matlab on my PC.
Obviously Rasberry and my PC are conntected on the same LAN.
Any idea?

Hi Cosimo,
One approach is to use the "timer" feature in MATLAB and in the timer callback, you can call the function which reads the cpu temperature( probably using "system" command of Raspbery Pi Support package).
Please see the below timer example for reference:
Alternatively, you may find the "Raspberry Pi Resource Monitor App" handy for similar usecases.
