Most USB applications and products operate as USB devices, rather than USB hosts. This

demonstration will show how the DE4 board is operated as a USB device by connecting it to a host

computer. In this demonstration, the USB port 1 (mini-AB port) on the DE4 is configured as a

device port to connect with a host computer. The NIOS II processor communicates with host

computer through USB Bulk Transfer with user-defined command sets. The USB device driver is

implemented in NIOS C code. From the host computer side, a test program is used to communicate

with DE4. The test program can configure LED status and poll button status through the USB

connection.



Nios II Software Architecture

The hardware system block diagram of this demonstration is the same as the USB Host.

Figure 5–7

shows the architectural layers of a NIOS II software stack of this demonstration.
