The ultimate goal of our Bachelors Thesis one year ago was to deliver a “market-ready” version of our oscilloscope project where you can just install an app from the market and connect the oscilloscope over USB.
Before the “Tablet Age” our idea was to set up the OTG port of a phone for host mode. However, this requires rooting the phone as well as adding a voltage supply to the connector. Not a very elegant solution.
When the first tablets with honeycomb arrived (3.0) we managed to use the host port on a rooted device to get our oscilloscope working. Still, root was required.
With Honeycomb 3.1 it was not only possible to acquire permission of the USB device it also became possible to program USB with the Java API rather than to go native with libusb.
Therefore we have written a tablet optimized version of our oscilloscope. With the all new user interface comes the ability to connect to our USB oscilloscope. You can get the application from the Android Market with your 3.0 and up tablet. Get the source code: HoneyOsciPrime.tar.gz, or the APK HoneyOsciPrime.apk. You can always download our Layout Files here and build your own oscilloscope or contact us for support.
