the board. The operation is as same as recording audio from MIC.
3.9 Overall Structure of the DE2-70 Control Panel
The DE2-70 Control Panel is based on a NIOS II system running in the Cyclone II FPGA with the
SDRAM-U2 or SSRAM. The software part is implemented in C code; the hardware part is
implemented in Verilog code with SOPC builder, which makes it possible for a knowledgeable user
to change the functionality of the Control Panel. The code is located inside the
DE2_70_demonstrations directory on the DE2 System CD-ROM.
To run the Control Panel, users must first configure it as explained in Section 3.1. Figure 3.13
depicts the structure of the Control Panel. Each input/output device is controlled by the NIOS II
Processor instantiated in the FPGA chip. The communication with the PC is done via the USB
Blaster link. The NIOS II interprets the commands sent from the PC and performs the
corresponding actions.
