Arduino控制PS2无线手柄

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 <PS2X_lib.h>

#include <PS2X_lib.h>  //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*************
  
error = ps2x.config_gamepad(13,11,10,12, true, true);   //setup pins and settings:  GamePad(clock, command, attention, data, Pressures?, Rumble?) check for error

if(error == 0){
   Serial.println("Found Controller, configured successful");
   Serial.println("Try out all the buttons, X will vibrate the controller, faster as you press harder;");
  Serial.println("holding L1 or R1 will print out the analog stick values.");

void loop(){

   Read GamePad and set vibration values

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

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

这样就连接成功了!
