Hello, I need to solve an easy problem... apparently. Briefly, I want to do something like an oscilloscope with Matlab, receiving a signal via USB. I have done all the previous steps: I have my USB working, I have check that the computer receives the right data, etc.
Now, the problem is how to get data with Matlab. It's a simple communication, with one direction (USB to PC, with bulk transfers - but I could change this type), and I just need to read that data, just 2 bytes of data received continuously (because it's a digital signal with 16 bits resolution).
Thanks for your help.

Thank you! I'll bookmark the Vendors links for it and their website.
It'd be nice if there was a way to generate a relatively low-priority interrupt rather than having to poll it. Maybe some day...

Image Analyst -- you mean you develop those "4 pictures for $1" booths that are found in malls? ;-)

Thanks everyone for the info. I am using a PSoC device, and I found an easy way to communicate with PC: making USB work as a COM port, so I can easyly process data with Matlab :)
