Controlling the 7-Segment Displays
■ Configure user ports
■ Load music to memory and play music via the audio digital analog
converter (DAC) output
■ Load an image pattern for VGA output
The following sections describe how to perform these actions with the
Control Panel already open on the host computer. If not already open,
launch the Control Panel as described in
“Control Panel Start” on

Controlling the
7-Segment
Displays Typical design activities do not require the ability to set arbitrary values
into simple display devices. However, used for troubleshooting, this
ability enables the user to verify that these devices operate correctly.
To set the value of a 7-segment module to display, perform the following
steps:
1. Select the PS2 & LED tab on the Control Panel ( Figure 4–2 ).

2. In the LED & 7-SEG area, enter a value for any of the 7-segment
modules labeled HEX0 through HEX3.
