   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.
