We can apply the IR receiver to many applications, such as integrating to the SD Card Demo, and

you can also develop other related interesting applications with it.

 Demonstration Setup, File Locations, and Instructions

• Project directory: DE2_115_IR

• Bit stream used: DE2_115_IR.sof

• Load the bit stream into the FPGA by executing

DE2_115_IR\demo_batch\DE2_115_IR.bat file

• Point the IR receiver with the remote-controller and press any button

Table 6-4 shows how the received code and key data display on eight 7-segment displays.
