1，关于arduino PS2手柄
从网上购买的山寨手柄，高仿Sony 手柄。
卖货的也没有提供详细资料。
还需要自己研究：
2，设备接入
买的时候带了一个接头，这个接头里面的线粗，用普通的杜邦线还不行。
一定不要把正负极接错了。输入 3.3v 的电压也可以：
ESP32 接线图：
折腾半天，这里用到 ESP32 的是安信可的，找的是官方的引脚。
用到的是 P18,P19,P32,P5 这个四个做为数据引脚，还有两个接上电源 3.3 电源和 GND 就行了。
3，Arduino代码
接线是一方面，有会就接好了，但是代码一直运行不成功，最后上 LIB 里面才发现，只支持 ESP8266 写了个宏，没写 ESP32 ，晕。
修改好了之后偶尔可以偶尔不行。开启日志可以，但是关闭不行。
后来发现，在setup 上访问配置的时候，设备还没有初始化，2 秒才能连上。我的天。
修改了代码。才可以。
替换：
#ifdef ESP8266
成：
#if defined(ESP8266) || defined(ESP32)
while (error != 0) {
delay(1000);// 1 second wait
//setup pins and settings: GamePad(clock, command, attention, data, Pressures?, Rumble?) check for error
error = ps2x.config_gamepad(PS2_CLK, PS2_CMD, PS2_SEL, PS2_DAT, pressures, rumble);
Serial.print("#try config ");
Serial.println(tryNum);
tryNum ++;
}
放在 wile 循环里面了。
直接克隆项目到 /arduino/libraries 目录下。

使用ESP32 测试：

按键都可以使用呢，特别注意，两个遥感杆要获得数据必须同时按住L1，R1，才可以。
然后就有 Stick 数据了。其他按键都是直接按下获得数据。
3，总结
本次进行开发正好是因为 ESP8266 设备接着别的东西呢，不想拆，正好手上有ESP32设备。
结果导致人家的库不支持，折腾半天，看了人家的Lib库代码，发现开发个库特别方便呢。
于是修改代码继续研究，由于不是正品手柄，导致获得配置总是时好时坏。
后来根据 WIFI的那样进行 while 循环，发现 2秒才识别上。怪不得老是失败呢。
解决了 lib 支持 esp32 的宏，和循环调用的问题，终于可以了。
没有玩过游戏，不太熟悉这个手柄，看文档知道了需要同时 按下 R1 L1 即可。
然后在控制小车啥的就特别的方便了。
