前言
使用的是開源社區(qū)貢獻(xiàn)的arduino PS2X庫市面上也有不少PS2手柄，但是長(zhǎng)得和PS2原裝手柄有區(qū)別，這種手柄可以在PS2主機(jī)上使用，不一定可以配合此庫使用，這也是因?yàn)檫@個(gè)庫是逆向破解PS2協(xié)議的原因，所以肯定有哪里不太完美。
先來看看硬件連接圖

然后把附件中的PS2X庫安裝到ArduinoIDE中。點(diǎn)擊下載附件 提取碼: 51pp 我用的Arduino是1.8的版本
安裝PS2X的教程：
選擇項(xiàng)目-->加載庫-->添加ZIP-->選擇附件中的ps2x_lib 即可
此代碼是示例：
#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; //左電機(jī)后退(IN1)
int Left_motor_go=5; //左電機(jī)前進(jìn)(IN2)
int Right_motor_go=6; // 右電機(jī)前進(jìn)(IN3)
int Right_motor_back=10; // 右電機(jī)后退(IN4)

將示例代碼上傳到UNO板中
打開ps2無線手柄的開關(guān) 觀察無線接收器的綠燈 與手柄的上的燈 都停止閃爍說明連接成功了。
打開串口監(jiān)視器

如圖就是連接成功的顯示
我們按下手柄的按鍵 則會(huì)顯示對(duì)應(yīng)文字

這樣就連接成功了！
