首先,需要将MPU6050连接到Arduino板上,并使用I2C通信协议读取传感器数据。然后,将Arduino与Unity连接,将传感器数据传递到Unity中。
以下是一些基本的步骤:
1. 连接MPU6050到Arduino
使用以下代码将MPU6050连接到Arduino:
#include<Wire.h>
const int MPU_addr=0x68;
int16_t AcX,AcY,AcZ,Tmp,GyX,GyY,GyZ;
void setup(){
Wire.begin();
Wire.beginTransmission(MPU_addr);
Wire.write(0x6B);
Wire.write(0);
Wire.endTransmission(true);
Serial.begin(9600);
}
void loop(){
Wire.beginTransmission(MPU_addr);
Wire.write(0x3B);
Wire.endTransmission(false);
Wire.requestFrom(MPU_addr,14,true);
AcX=Wire.read()<<8|Wire.read();
AcY=Wire.read()<<8|Wire.read();
AcZ=Wire.read()<<8|Wire.read();
Tmp=Wire.read()<<8|Wire.read();
GyX=Wire.read()<<8|Wire.read();
GyY=Wire.read()<<8|Wire.read();
GyZ=Wire.read()<<8|Wire.read();
Serial.print("Accelerometer: ");
Serial.print("X=");
Serial.print(AcX);
Serial.print(" Y=");
Serial.print(AcY);
Serial.print(" Z=");
Serial.println(AcZ);
Serial.print("Gyroscope: ");
Serial.print("X=");
Serial.print(GyX);
Serial.print(" Y=");
Serial.print(GyY);
Serial.print(" Z=");
Serial.println(GyZ);
Serial.println();
delay(500);
}
2. 将传感器数据发送到Unity
使用以下代码将传感器数据发送到Unity:
#include <SoftwareSerial.h>
SoftwareSerial mySerial(2, 3); // RX, TX
const int MPU_addr=0x68;
int16_t AcX,AcY,AcZ,Tmp,GyX,GyY,GyZ;
void setup(){
Wire.begin();
Wire.beginTransmission(MPU_addr);
Wire.write(0x6B);
Wire.write(0);
Wire.endTransmission(true);
Serial.begin(9600);
mySerial.begin(9600);
}
void loop(){
Wire.beginTransmission(MPU_addr);
Wire.write(0x3B);
Wire.endTransmission(false);
Wire.requestFrom(MPU_addr,14,true);
AcX=Wire.read()<<8|Wire.read();
AcY=Wire.read()<<8|Wire.read();
AcZ=Wire.read()<<8|Wire.read();
Tmp=Wire.read()<<8|Wire.read();
GyX=Wire.read()<<8|Wire.read();
GyY=Wire.read()<<8|Wire.read();
GyZ=Wire.read()<<8|Wire.read();
String data = "Accelerometer:" + String(AcX) + "," + String(AcY) + "," + String(AcZ) + "; Gyroscope:" + String(GyX) + "," + String(GyY) + "," + String(GyZ) + ";";
mySerial.println(data);
Serial.println(data);
delay(500);
}
3. 在Unity中接收传感器数据
使用以下代码在Unity中接收传感器数据:
using System.Collections;
using System.Collections.Generic;
using UnityEngine;
using System.IO.Ports;
public class Arduino : MonoBehaviour {
public SerialPort serialPort = new SerialPort("COM4", 9600);
public string[] sensorData;
void Start () {
serialPort.Open();
}
void Update () {
if (serialPort.IsOpen) {
string data = serialPort.ReadLine();
sensorData = data.Split(';');
}
}
}
以上是一些基本的步骤,你可以根据自己的需要进行修改和扩展。
