2.3、Principle of control

Principle of control

module	feature
PS2 handle receiver	Communication with the single chip microcomputer

Key value rule：

Key nameKey value
L1	11
L2	9
R1	12
R2	10
Arrow keys (up, down, left and right)	5/7/8/6
Function key（X/A/Y/B）	16/15/13/14
Select key	1
Start key	4

Note: The above key values are from the project code

PS2 handle is composed of a handle and a receiver. The handle is mainly responsible for sending key information. The receiver is connected to the microcontroller for receiving the information from the handle and passing it to the microcontroller. The microcontroller can also send commands to the handle through the receiver to configure the sending mode of the handle.

For the application layer, you can read the source code in the project files yourself

4、Experimental phenomenon


xxxxxxxxxx
Program download can refer to [2, development environment construction and use: program download and simulation]

After downloading the program successfully, connect the handle receiver to the expansion board.

Turn on the switch on the handle, and then we need to pair the handle receiver with the handle.

The pairing indicator is shown below: The handle receiver and the handle indicator are the traffic light is always on, if it is not, you can long press the "Mode" button on the handle to switch the handle mode to red and green mode.

See the demo video for details：
