PS2无线手柄使用手册

   2.4G无线遥控手柄通过USBhost模块和主控板通讯，使用是必须连同USBhost模块一起用。

  手柄外观及按位介绍：

1、手柄通电后，上方的红色电源指示灯(POWER)会常亮，进入休眠或者关闭状态时灭掉。

2、一般情况下，只要USB接收器通电，手柄会自动连接。

3、配对成功后，按“MODE”键，选择手柄发送模式，有2种模式可以切换，同时对应“MODE LED”指示灯亮起或熄灭。我们的程序采用其中摇杆输出模拟值的方式，也就是这个绿灯常亮的模式，用户注意切换好。

4、手柄特性：此手柄具有自动休眠省电模式。在开启无配对状态下，30s后启动省电模式；开启并配对完成的状态下，5分钟无按键按下，启动省电模式。此时只要按下START就能激活。

    该模块支持的图形化编程平台目前有WeeeCode 3.0，其图形化编程指南如下：

Arduino编程示例:

#include "WeELF328P.h"
#include "SoftwareSerial.h"

WeUSBHost PS2(A3, A2);  //A3,A2 for 328P

void setup()
{
  Serial.begin(9600);
  PS2.init(USB2_0);  
  delay(10);
}

手柄和USB接收器是配套使用的，手柄只连接出厂配套的USB接收器，不能连接其它手柄的USB接收器，所以不要弄丢接收器。

如果多个手柄同时使用时，可能会出现信号干扰，造成手柄连接中断的情况，此时尽量和其它手柄接、收器拉开距离，使干扰降低。
