 +In order to use the demo, you will need to connect a circuit to the XADC Pmod Port in order to measure a voltage. The following example shows a voltage divider that produces each voltage between 0 V and 1 V in increments of 0.33 V. This circuit uses a chain of three 1 kΩ resistors in series with a 4.7 kΩ and a 2.2 kΩ resistor. The circuit is tied to the 3V3 and GND pins of the XADC Pmod header to provide power. Each of the 'n' pins, the lower row of the XADC port, are connected to ground.

 +===== XADC Channels =====
 +
 +Each analog input channel will control the brightness of an LED as shown in the following table:
 +
 +| Channel Name ^ LED # ^ Pmod Pin #s ^
 +^ AD14  | LD0  | 1 & 7  |
 +^ AD7   | LD1  | 2 & 8  |
 +^ AD15  | LD2  | 3 & 9  |
 +^ AD6   | LD3  | 4 & 10  |
 +
 +Changing Voltages by reconfiguring the circuit while the demo is running is fine. If you built the example circuit shown in the "Using the Latest Release" section, above, feel free to move jumpers around to test out the different nodes of the voltage divider.
