Installation and Operation

2.5 DEMO WITH PICDEM DEMO BOARD

There is one demo for this daughter board. The demo has an assembly versions for the

PICDEM HPC Explorer Demo Board and the PICDEM FS USB Demo Board.

The following hardware is required for this demo:

• PC with MPLAB-IDE installed

•ICD 2

• PICDEM HPC Explorer Demo Board (and power supply)

• 4 Channel oscilloscope

Figure 2-7 shows the Resistor Network circuit configuration for the demo. To create this

circuit, the Jumper configuration and oscilloscope connection points for the demo are

shown in Figure 2-8.

The output waveform is shown in Figure 2-10. For this waveform, the U1-Pot0 is win-

dowed by forcing U2-Pot0 and U2-Pot1 to mid-scale. The Wiper (U1-P0W) is loaded

with values to create a Triangle waveform. U1-Pot1 is connected to Power and Ground,

and the Wiper (U1-P1W) is loaded with values to create an inverse Triangle waveform.

Note: An oscilloscope with fewer channels can be used, but this will reduce the

information that can be displayed.
