前言
使用的是开源社区贡献的arduino PS2X库市面上也有不少PS2手柄，但是长得和PS2原装手柄有区别，这种手柄可以在PS2主机上使用，不一定可以配合此库使用，这也是因为这个库是逆向破解PS2协议的原因，所以肯定有哪里不太完美。
先来看看硬件连接图

然后把附件中的PS2X库安装到ArduinoIDE中。点击下载附件 提取码: 51pp 我用的Arduino是1.8的版本
安装PS2X的教程：
选择项目-->加载库-->添加ZIP-->选择附件中的ps2x_lib 即可
此代码是示例：
#include
#include //for v1.6
PS2X ps2x; // create PS2 Controller Class
//right now, the library does NOT support hot pluggable controllers, meaning
//you must always either restart your Arduino after you conect the controller,
//or call config_gamepad(pins) again after connecting the controller.
int Left_motor_back=9; //左电机后退(IN1)
int Left_motor_go=5; //左电机前进(IN2)
int Right_motor_go=6; // 右电机前进(IN3)
int Right_motor_back=10; // 右电机后退(IN4)
int Right_motor_en=8; // 右电机前进(EN2)
int Left_motor_en=7; // 右电机后退(EN1)
int error = 0;
byte type = 0;
byte vibrate = 0;
void setup(){
Serial.begin(57600);
//初始化电机驱动IO为输出方式
pinMode(Left_motor_go,OUTPUT); //
pinMode(Left_motor_back,OUTPUT); //
pinMode(Right_motor_go,OUTPUT);//
pinMode(Right_motor_back,OUTPUT);//
//CHANGES for v1.6 HERE!!! **************PAY ATTENTION*************

将示例代码上传到UNO板中
打开ps2无线手柄的开关 观察无线接收器的绿灯 与手柄的上的灯 都停止闪烁说明连接成功了。
打开串口监视器
image
如图就是连接成功的显示
我们按下手柄的按键 则会显示对应文字
image
这样就连接成功了！
