DE2-70 User Manual Chapter 3 DE2-70 Control Panel The DE2-70 board comes with a Control Panel facility that allows users to access various components on the board from a host computer. The host computer communicates with the board through an USB connection. The facility can be used to verify the functionality of components on the board or be used as a debug tool while developing RTL code. This chapter first presents some basic functions of the Control Panel, then describes its stru
