控制器在我们的生活中有着悠久的历史；从控制遥控车和四轮车到游戏控制器......，他们都使用无线或有线控制器。在本篇文章中，您将学习如何使用Arduino连接和使用PS2游戏机控制器。

PS2控制器的功能

每个人都知道索尼游戏机称为PlayStation。索尼游戏控制器有12个对压力敏感的模拟键（4个方向键、4个操作键、十字、三角、圆形和方形，L1、L2、R1和R2）和5个数字键（MODE，START，SELECT， R3，L3）和2个模拟操纵杆。

控制器内部有2个电机，由于它们的不平衡才会产生振动。

无线控制器工作频率为2.4GHz，射程为10米。它还有一个用于发送和接收数据的光学指示器。该控制器仅需3节AAA电池供电（在某些情况下，它只需要2节AAA电池）。

你可以使用PS2控制器：

● 控制轮式机器人和遥控车

● 控制机器人手臂

● 控制相机

● 控制飞行机器人

● ..

PS2控制器引脚分布说明

PS2控制器接收器包括9个引脚：

1. Data：主机线，用于向从站发送数据（MOSI）

2. Command：从机线，用于向主站发送数据（MISO）

3. Vibration：振动电机的电源; 7.2V至9V

4. Ground：电路接地

5. VCC：电源供电; 3.3伏

6. Attention：CS或芯片选择引脚用于调用从机并准备连接

7. Clock：相当于时钟的SCK引脚

8. No Connection：没用

9. Acknowledge：从控制器到PS2接收器的应答信号

连接PS2控制器和Arduino

为了使用PS2控制器，您需要将控制器的按键引入Arduino。然后根据您的项目为每个键选择适当的功能。

电路连接

代码

在代码中，您需要PS2X库。将库添加到Arduino后，您可以打开PS2X库示例或复制以下代码并将其上载到您的主板上。您可以通过按不同的键在串行监视器窗口中查看结果。

#include #include <PS2X_lib.h>
PS2X ps2x;
//right now, the library does NOT support hot-pluggable controllers, meaning
//you must always either restart your Arduino after you connect the controller,
//or call config_gamepad(pins) again after connecting the controller.
int error = 0;
byte type = 0;
byte vibrate = 0;
void setup(){
Serial.begin(57600);
error = ps2x.config_gamepad(13,11,10,12, true, true); //GamePad(clock, command, attention, data, Pressures?, Rumble?)
if(error == 0){
Serial.println("Found Controller, configured successful");
Serial.println("Try out all the buttons, X will vibrate the controller, faster as you press harder;");
Serial.println("holding L1 or R1 will print out the analog stick values.");
Serial.println("Go to www.billporter.info for updates and to report bugs.");
}
else if(error == 1)
Serial.println("No controller found, check wiring, see readme.txt to enable debug. visit www.billporter.info for troubleshooting tips");
else if(error == 2)
Serial.println("Controller found but not accepting commands. see readme.txt to enable debug. Visit www.billporter.info for troubleshooting tips");
else if(error == 3)
Serial.println("Controller refusing to enter Pressures mode, may not support it. ");
type = ps2x.readType();
switch(type) {
case 0:
Serial.println("Unknown Controller type");
break;
case 1:
Serial.println("DualShock Controller Found");
break;
case 2:
Serial.println("GuitarHero Controller Found");
break;
}
}
void loop(){
/* You must Read Gamepad to get new values
Read GamePad and set vibration values
ps2x.read_gamepad(small motor on/off, larger motor strenght from 0-255)
if you don't enable the rumble, use ps2x.read_gamepad(); with no values
you should call this at least once a second
*/
if(error == 1)
return;
if(type == 2){
ps2x.read_gamepad(); //read controller
if(ps2x.ButtonPressed(GREEN_FRET))
Serial.println("Green Fret Pressed");
if(ps2x.ButtonPressed(RED_FRET))
Serial.println("Red Fret Pressed");
if(ps2x.ButtonPressed(YELLOW_FRET))
Serial.println("Yellow Fret Pressed");

Serial.println("Star Power Command");
if(ps2x.Button(UP_STRUM)) //will be TRUE as long as button is pressed
Serial.println("Up Strum");
if(ps2x.Button(DOWN_STRUM))
Serial.println("DOWN Strum");
if(ps2x.Button(PSB_START)) //will be TRUE as long as button is pressed
Serial.println("Start is being held");
if(ps2x.Button(PSB_SELECT))
Serial.println("Select is being held");
if(ps2x.Button(ORANGE_FRET)) // print stick value IF TRUE
{
Serial.print("Wammy Bar Position:");
Serial.println(ps2x.Analog(WHAMMY_BAR), DEC);
}
}
else { //DualShock Controller
ps2x.read_gamepad(false, vibrate); //read controller and set large motor to spin at 'vibrate' speed
if(ps2x.Button(PSB_START)) //will be TRUE as long as button is pressed
Serial.println("Start is being held");
if(ps2x.Button(PSB_SELECT))
Serial.println("Select is being held");
if(ps2x.Button(PSB_PAD_UP)) { //will be TRUE as long as button is pressed

Serial.println(ps2x.Analog(PSAB_PAD_DOWN), DEC);
}
vibrate = ps2x.Analog(PSAB_BLUE); //this will set the large motor vibrate speed based on
//how hard you press the blue (X) button
if (ps2x.NewButtonState()) //will be TRUE if any button changes state (on to off, or off to on)
{
if(ps2x.Button(PSB_L3))
Serial.println("L3 pressed");
if(ps2x.Button(PSB_R3))
Serial.println("R3 pressed");
if(ps2x.Button(PSB_L2))
Serial.println("L2 pressed");
if(ps2x.Button(PSB_R2))
Serial.println("R2 pressed");
if(ps2x.Button(PSB_GREEN))
Serial.println("Triangle pressed");
}
if(ps2x.ButtonPressed(PSB_RED)) //will be TRUE if button was JUST pressed
Serial.println("Circle just pressed");
if(ps2x.ButtonReleased(PSB_PINK)) //will be TRUE if button was JUST released
Serial.println("Square just released");
if(ps2x.NewButtonState(PSB_BLUE)) //will be TRUE if button was JUST pressed OR released
Serial.println("X just changed");
if(ps2x.Button(PSB_L1) || ps2x.Button(PSB_R1)) // print stick values if either is TRUE
{
Serial.print("Stick Values:");
Serial.print(ps2x.Analog(PSS_LY), DEC); //Left stick, Y axis. Other options: LX, RY, RX
Serial.print(",");
Serial.print(ps2x.Analog(PSS_LX), DEC);

}
}
delay(50);
}

以下是该代码库中最实用的函数：

ps2x.config_gamepad(clock, command, attention, data, Pressures? Rumble?);函数设置控制器引脚和对电机压力和振动的敏感性。如果您希望键对压力不敏感，或者电机没有振动，请将“Pressures”和“Rumble”设置为“false”。此函数返回错误值。

ready();函数确定检测到的控制器类型。 0表示未正确检测到控制器，1表示检测到DualShock控制器，2表示检测到GuitarHero控制器。

read_gamepad(boolean motor1, byte motor2);当确定电动机的振动状态时，该函数开始读取键的状态。

Button (but type);当按下函数参数中的特定键时，该函数返回1。

Analog (but type);函数返回模拟键值，然后您可以相应地决定您的操作。

以上就是本篇文章的全部内容。接下来，您可以尝试通过按下方向键来控制遥控车，使其向不同的方向移动。汽车的速度随着按键上的压力而变化。按下方形键，汽车会发出蜂鸣声，按下十字键打开灯光。如果有任何问题，请随时在本帖下面进行回复。
