User Interfaces
User-Defined LEDs (D2 Through D9)
The Cyclone II DSP development board provides eight user-defined
LEDs. D2 through D9 are connected to general purpose I/O pins on the
EP2C70 FPGA as listed in
Table 2–3 . When the EP2C70 FPGA drives logic
0, the corresponding LED turns on.
Figure 2–3 shows the user-defined LEDs.
