Demonstration Setup, File Locations, and Instructions

Project directory: DE2_70_NIOS_HOST_MOUSE_VGA

Bit stream used: DE2_70_NIOS_HOST_MOUSE_VGA.sof

Nios II Workspace: DE2_70_NIOS_HOST_MOUSE_VGA\Software

•Connect a USB Mouse to the USB Host Connector (type A) of the DE2-70 board

•Connect the VGA output of the DE2-70 board to a VGA monitor (both LCD and CRT type of monitors should work)

•Load the bit stream into FPGA

•Run the Nios II and choose DE2_70_NIOS_HOST_MOUSE_VGA as the workspace. Click on the Compile and Run button

•You should now be able to observe a blue background with an Altera logo on the VGA display

•Move the USB mouse and observe the corresponding movements of the cursor on the screen

•Left-click mouse to draw white dots/lines and right-click the mouse to draw blue dots/lines on the screen.

Figure 6.6 illustrates the setup for this demonstration.
