Hi,

I am working on a project which requires to record simultaneously the camera, gyroscope and accelerometer data of my Iphone. I would like to use Matlab/Simulink.

Maybe I am wrong but I just saw the option to record video with Simulink?

Finally, I properly set up my IOS with Simulink device and I tried the predefined examples. I get into trouble since I didn't find a way to acquire the data into Matlab/Simulink. For example when I add an accelerometer block into Simulink and I display the data on the IOS device it works perfectly but as soon as I add a scope the program can not run anymore.

I tried to use the UDP send/receiver provided in the examples but I didn't receive any data.

Maybe someone has ever had a similar problem?

Thank you in advance, Pm

Hi,

Finally I found a way to make the UDP send/receiver work. But I am in front of another problem. It is not possible to send a matrix via the UDP blocks only [1xN] vectors. It means that for a 640x480 image size I need to connect at least 480 UDP blocks for each color R,G and B.

Another solution?

Thank you,
