This demo can be used to measure any voltage between 0 and 1 volt. The brighter the led, the closer to 1 the voltage is. The voltages below are 0.5V and 0.1V. The circuit below uses a chain of ten 1KOhm resistors in series with two parallel 47KOhm resistors tied to the 3V3 and GND pins of the XADC Pmod header to create these voltages. |

| - | This portion will help you run the demo and observe all its features. The demo reads analog data in from each enabled xadc channel (set the associated switch to the high position to enable that channel) and sets the brightness on the associated led linearly. Higher voltage = brighter led. | + | |
