ADC Niose test Connect four analog signals to your MBED. and then run the Windows app. The four traces are displayed on an oscilloscope like display. I have used a USB HID DEVICE link, so connections to D+, D- are required. The MBED code is otherwise quite basic, So you can modify it to your own test needs. Additionaly, there is a 16 bit count value, in my MBED code Mainly to test if MSB & LSB are correct.
