arduino环境下用ESP32连接PS2手柄

一、PS2接线说明

功能&＃xff1a;
1&＃xff0c;数据&＃xff1a;控制器- > PlayStation 游戏机。这是一个集电极开路输出&＃xff0c;需要一个上拉电阻&＃xff08;10K&＃xff0c;或许更多&＃xff09;。&＃xff08;上拉电阻是必要的&＃xff0c;因为控制器只能连接线对地&＃xff0c;它不能真正把电压就行了&＃xff09;。
2&＃xff0c;命令&＃xff1a;PlayStation - >控制器。
4&＃xff0c;地线&＃xff0c;接电源负极。
5&＃xff0c;电源&＃xff1a;任何官方的索尼控制器应在 3-5V。
6&＃xff0c;注意&＃xff1a;各组发送/接收的字节前&＃xff0c;此行必须被拉低&＃xff0c;然后重新置高之后。在我们的测试中&＃xff0c;它是不足够的&＃xff0c;以配合永久-它被赶下来&＃xff0c;周围每一组 Digitan 认为这是一个“片选”或“从选择”行&＃xff0c;是用来解决不同的控制器上在同一总线上。
7&＃xff0c;时钟&＃xff1a; 500kH / Z&＃xff0c;通常高。似乎是 SPI 总线的通信。我们已经得到了它的工作为 500kHz 小于 100kHz 的上升&＃xff0c;&＃xff08;500K比特/秒&＃xff0c;这还不算字节和数据包之间的延迟&＃xff09;。吉他英雄控制器连接时&＃xff0c;时钟频率是 250kHz&＃xff0c;这也是游戏站 1 使用的速率。
最后特别需要提醒的是&＃xff1a;
按下遥控器的 MODE 键&＃xff0c;手柄可配置成“红灯模式”或者“绿灯模式”&＃xff0c;当遥控器侧面的 “MODE LED”亮为红灯模式&＃xff0c;反之为绿灯模式&＃xff0c;“红灯模式”和“绿灯模式”的主要区别是摇杆模拟值得输出。
红灯模式时&＃xff1a;左右摇杆发送模拟值&＃xff0c;0x00〜OxFF 之间&＃xff0c;且摇杆按下的键值 L3、R3 有效&＃xff1b;
绿灯模式时&＃xff1a;左右摇杆模拟值为无效&＃xff0c;推到极限时&＃xff0c;对应发送 UP、RIGHT、DOWN、LEFT、△、〇、X、□&＃xff0c;按键 L3、R3 无效。

三、注意

在下载程序时先将PS2的接线断开&＃xff0c;否则会下载失败。
在运行程序时将PS2的供电连到3.3V上&＃xff0c;否则用可能导致错误以至于芯片不断重启
在程序测试时注意L1和R1按键按下时并不显示相应按键按下而是不断传输两个摇杆的坐标信息&＃xff0c;换句话说&＃xff0c;想要获取两摇杆的坐标信息&＃xff0c;需要按下L1或R1才可。
