arduino学习笔记24 - PS2无线手柄实验
本帖最后由 弘毅 于 2012-12-4 18:36 编辑用无线手柄通过arduino控制电机或者舵机之类的，是不是感觉很遥远。。。光那底层的通信协议就吓跑了。。。
不用怕。。有开源社区贡献的arduino PS2X库，一切皆有可能。
先说明一下手柄的要求，此PS2X库，尽量是使用PS2原装手柄，或者与之外观一样的。无线手柄可以直接接arduino使用，有线手柄因为arduino的3.3V供电不足，需要单独供电。
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，笔者就遇到这个问题。。。。。买回来的罗技手柄虽然手感一流，但是@@部分按键反应不灵敏（PS2主机上完美）。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。
先上硬件连接图，按照图示把线接好。
然后把论坛附件中的PS2X库解压缩后放入IDE的libraries文件夹中。把下面代码复制进IDE编译，下载到arduino板子上。此代码就是PS2X库的示例，详细库使用方法请查看库中的说明文件#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 error = 0;
byte type = 0;
byte vibrate = 0;
void setup(){
Serial.begin(57600);
//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.");
Serial.println("Go to www.billporter.info for updates and to report bugs.");
}
else if(error == 1)
Serial.println("No controller found, check wiring, see readme.txt to enable debug. visit www.billporter.info for troubleshooting tips");
else if(error == 2)
Serial.println("Controller found but not accepting commands. see readme.txt to enable debug. Visit www.billporter.info for troubleshooting tips");
else if(error == 3)
Serial.println("Controller refusing to enter Pressures mode, may not support it. ");
//Serial.print(ps2x.Analog(1), HEX);
type = ps2x.readType();
switch(type) {
case 0:
Serial.println("Unknown Controller type");
break;
case 1:
Serial.println("DualShock Controller Found");
break;
case 2:
Serial.println("GuitarHero Controller Found");
break;
}
}
void loop(){
/* You must Read Gamepad to get new values
Read GamePad and set vibration values
ps2x.read_gamepad(small motor on/off, larger motor strenght from 0-255)
if you don't enable the rumble, use ps2x.read_gamepad(); with no values
you should call this at least once a second
*/
if(error == 1) //skip loop if no controller found
return;
if(type == 2){ //Guitar Hero Controller
ps2x.read_gamepad(); //read controller
if(ps2x.ButtonPressed(GREEN_FRET))
Serial.println("Green Fret Pressed");
if(ps2x.ButtonPressed(RED_FRET))
Serial.println("Red Fret Pressed");

if(ps2x.ButtonPressed(STAR_POWER))
Serial.println("Star Power Command");
if(ps2x.Button(UP_STRUM)) //will be TRUE as long as button is pressed
Serial.println("Up Strum");
if(ps2x.Button(DOWN_STRUM))
Serial.println("DOWN Strum");
if(ps2x.Button(PSB_START)) //will be TRUE as long as button is pressed
Serial.println("Start is being held");
if(ps2x.Button(PSB_SELECT))
Serial.println("Select is being held");
if(ps2x.Button(ORANGE_FRET)) // print stick value IF TRUE
{
Serial.print("Wammy Bar Position:");
Serial.println(ps2x.Analog(WHAMMY_BAR), DEC);
}
}
else { //DualShock Controller
ps2x.read_gamepad(false, vibrate); //read controller and set large motor to spin at 'vibrate' speed

Serial.println(ps2x.Analog(PSAB_PAD_DOWN), DEC);
}
vibrate = ps2x.Analog(PSAB_BLUE); //this will set the large motor vibrate speed based on
//how hard you press the blue (X) button
if (ps2x.NewButtonState()) //will be TRUE if any button changes state (on to off, or off to on)
{
if(ps2x.Button(PSB_L3))
Serial.println("L3 pressed");
if(ps2x.Button(PSB_R3))
Serial.println("R3 pressed");
if(ps2x.Button(PSB_L2))

if(ps2x.Button(PSB_R2))
Serial.println("R2 pressed");
if(ps2x.Button(PSB_GREEN))
Serial.println("Triangle pressed");
}
if(ps2x.ButtonPressed(PSB_RED)) //will be TRUE if button was JUST pressed
Serial.println("Circle just pressed");
if(ps2x.ButtonReleased(PSB_PINK)) //will be TRUE if button was JUST released
Serial.println("Square just released");
if(ps2x.NewButtonState(PSB_BLUE)) //will be TRUE if button was JUST pressed OR released
Serial.println("X just changed");
if(ps2x.Button(PSB_L1) || ps2x.Button(PSB_R1)) // print stick values if either is TRUE
{
Serial.print("Stick Values:");
Serial.print(ps2x.Analog(PSS_LY), DEC); //Left stick, Y axis. Other options: LX, RY, RX
Serial.print(",");
Serial.print(ps2x.Analog(PSS_LX), DEC);
Serial.print(",");
Serial.print(ps2x.Analog(PSS_RY), DEC);
Serial.print(",");
Serial.println(ps2x.Analog(PSS_RX), DEC);
}
}
delay(50);
}然后打开串口监视器，看看实验效果吧。PS2手柄按键按下后，串口监视器就会传回是哪个按键，L1和R1按下后好像是读取几个口的模拟量~

附件就是PS2X库1.6版~目前最新的
来一个最新的支持1.0 IDE的库，是1.8版本的。
放一个1.41老版本的库，对各种手柄支持度比新库要好

顶你一个，一定要用PS2原装无线手柄么？
山寨原装的也可以。。。不要用啥第三方兼容的。。。比如我买的罗技，就不好用。。部分按键不灵光 :lol只要是使用 SONY 的PS2协议 就完全可以····· 强 就得意这种 崇拜啊，楼主继续加油 摇杆部分貌似还是没有进展啊 nomady 发表于 2011-12-14 11:30 static/image/common/back.gif
摇杆部分貌似还是没有进展啊
需要更多的人分享自己的学习经验和心得 你好 请问一下 我将程序复制到IDE中编译 怎么出现错误啊

你好 请问一下 我将程序复制到IDE中编译 怎么出现错误啊
实验实在0022 IDE中做的，如果你用1.0编译器，就会报错。 手头有个usb的北通手柄，怎么处理？？？:victory: 没摇杆呀。。。。 你好，我用的IDE是0022，已将PS2X_lib.h和PS2X_lib.cpp复制到libraries里，将程序复制到IDE里，报错是aggregate 'PS2X ps2x'has incomplete type and cannot be defined，不知道是什么原因？ volcano2012 发表于 2012-4-7 20:47 static/image/common/back.gif
你好，我用的IDE是0022，已将PS2X_lib.h和PS2X_lib.cpp复制到libraries里，将程序复制到IDE里，报错是aggre ...
不能直接放入libraries，要放入PS2或者其他名字的目录中 谢谢楼主昨天的解答。我把示例程序写入arduino板子后，且按照图示连接好硬件，烧写时手柄有时会振动。在监视器窗口出现乱码“ý.¢<Ž3|—8,8g}-ä”，重复几次乱码都不同。按下手柄按键都有反应，也出现乱码，每次乱码也不同，且没有Serial.println的空格和换行符，不知道什么原因？望解答
