arduino教程系列24-PS2无线手柄实验 手柄,无线,笔记,学习

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ARDUINO

//or call config_gamepad(pins) again after connecting the controller.

        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~


网盘http://pan.baidu.com/s/1dExdYV3下载下面软件

附件就是PS2X库1.6版~目前最新的

madsci1016-Arduino-PS2X-3e4a723.zip
来一个最新的支持1.0 IDE的库,是1.8版本的。

Arduino-PS2X-master.zip
放一个1.41老版本的库,对各种手柄支持度比新库要好

PS2X_lib_v1_41.zip
