converting my computer to an oscilloscope using usb port
Hello,Before getting my computer to work as an oscilloscope, I need to design some sort of input hardware that will serve as a source of analogue signal to my usb port. I need a simple design (schematics)that can serve as a probe to the usb port and a corresponding device driver.I am also stuck on how to write a software program in matlab to interprete these input signals to graphs on my computer.
please could you assist or refer me to any project on this subject.
Thanks.
