In this demonstration, the key-related information that the user has pressed on the remote
controller(Figure 6-18，Table
point the remote controller to the IR receiver on DE2-115 board and press the key. After the signal
being decoded and processed through FPGA, the related information will be displayed on the
7-segment displays in hexadecimal format, which contains Custom Code, Key Code and Inversed
Key Code. The Custom Code and Key Code are used to identify a remote controller and key on the
remote controller, respectively.
Next we will introduce how this information being decoded and then displayed in this demo.
When a key on the remote controller is pressed, the remote controller will emit a standard frame,
shown in
is the key-related information, and the last 1 bit end code represents the end of the frame.
