调出了两块uno互连的程序

wunanyx

这个程序有问题，我第二天又调试了一版，见楼下的~~~~~

这两天在坛子里找如何通过串口进行uno互连的程序，还是弘毅大版的et库最好
让我调出了两个uno互连的程序，一个uno连接gy-80，我读取角速度值，通过串口传给另个uno
接线方面，就用了两根线实现互连，一根是tx1对接，另一根有点意外，是gnd的对接。
[pre lang="arduino" line="1" file="tx"]#include <L3G4200D.h>
#include <Wire.h>
#include <EasyTransfer.h>
L3G4200D gyro;
//create object
EasyTransfer ET;

struct SEND_DATA_STRUCTURE{
  //put your variable definitions here for the data you want to send
  //THIS MUST BE EXACTLY THE SAME ON THE OTHER ARDUINO
  int gx;
};

//give a name to the group of data
SEND_DATA_STRUCTURE mydata;

void setup(){
  Serial.begin(9600);
  //start the library, pass in the data details and the name of the serial port. Can be Serial, Serial1, Serial2, etc.      
    Wire.begin();
  gyro.enableDefault();  
  ET.begin(details(mydata), &Serial);  
  pinMode(13, OUTPUT);  
  randomSeed(analogRead(0));
}

void loop(){
    gyro.read();  
int gx = gyro.g.x;  
  //send the data
  ET.sendData();
  Serial.println(gx);
  delay(100);
}[/code]
以上是发送方的程序，含一个4200的角速度取值
以下是接收方的程序

[pre lang="arduino" line="1" file="rx"]#include <SoftEasyTransfer.h>

/*   For Arduino 1.0 and newer, do this:   */
#include <SoftwareSerial.h>
SoftwareSerial mySerial(2, 3);

/*   For Arduino 22 and older, do this:   */
//#include <NewSoftSerial.h>
//NewSoftSerial mySerial(2, 3);


//create object
SoftEasyTransfer ET;

struct RECEIVE_DATA_STRUCTURE{
  //put your variable definitions here for the data you want to receive
  //THIS MUST BE EXACTLY THE SAME ON THE OTHER ARDUINO
  int gx;

};

//give a name to the group of data
RECEIVE_DATA_STRUCTURE mydata;

void setup(){
  mySerial.begin(9600);
  //start the library, pass in the data details and the name of the serial port.
  ET.begin(details(mydata), &mySerial);
  
  pinMode(13, OUTPUT);
  
}

void loop(){
  //check and see if a data packet has come in.
  if(ET.receiveData()){
    //this is how you access the variables. [name of the group].[variable name]
    //since we have data, we will blink it out.
  char x = mydata.gx;
    Serial.println(x);
  }
  //you should make this delay shorter then your transmit delay or else messages could be lost
  delay(100);
}[/code]

我用easytransfer那个库，进行了修改
以下是tx的代码，三个变量，xyz轴的角速度

1. #include <L3G4200D.h>
   
2. #include <Wire.h>
   
3. #include <EasyTransfer.h>
   
4. L3G4200D gyro;
   
5. //create object
   
6. EasyTransfer ET;
   
7. 
   
8. struct SEND_DATA_STRUCTURE{
   
9.   //put your variable definitions here for the data you want to send
   
10.   //THIS MUST BE EXACTLY THE SAME ON THE OTHER ARDUINO
    
11.   int gx;
    
12.   int gy;
    
13.   int gz;
    
14. };
    
15. 
    
16. //give a name to the group of data
    
17. SEND_DATA_STRUCTURE mydata;
    
18. 
    
19. void setup(){
    
20.   Serial.begin(9600);
    
21.   //start the library, pass in the data details and the name of the serial port. Can be Serial, Serial1, Serial2, etc.      
    
22.     Wire.begin();
    
23.   gyro.enableDefault();  
    
24.   ET.begin(details(mydata), &Serial);  
    
25.   pinMode(13, OUTPUT);  
    
26.   randomSeed(analogRead(0));
    
27. }
    
28. 
    
29. void loop(){
    
30.     gyro.read();  
    
31.   mydata.gx = gyro.g.x;
    
32.   mydata.gy = gyro.g.y;
    
33.    mydata.gz = gyro.g.z;
    
34.   //send the data
    
35.   ET.sendData();
    
36.   Serial.print(mydata.gx);
    
37.   Serial.print(" ");  
    
38.   Serial.print(mydata.gy);
    
39.     Serial.print(" ");
    
40.     Serial.println(mydata.gz);
    
41.   delay(100);
    
42. }

以下是rx端的代码

1. #include <EasyTransfer.h>
   
2. #include <LiquidCrystal_I2C.h>
   
3. LiquidCrystal_I2C lcd(0x27,16,2);  // set the LCD address to 0x27 for a 16 chars and 2 line display
   
4. #include <Wire.h>
   
5. //create object
   
6. EasyTransfer ET;
   
7. 
   
8. struct RECEIVE_DATA_STRUCTURE{
   
9.   //put your variable definitions here for the data you want to receive
   
10.   //THIS MUST BE EXACTLY THE SAME ON THE OTHER ARDUINO

23.           lcd.init();                      // initialize the lcd
    
24.   // Print a message to the LCD.
    
25.    lcd.backlight();
    
26.    lcd.print("Set success!");
    
27.   pinMode(13, OUTPUT);
    
28.   
    
29. }
    
30. 
    
31. void loop(){
    
32.   //check and see if a data packet has come in.

43.   //you should make this delay shorter then your transmit delay or else messages could be lost
    
44.   delay(100);
    
45. }
    
46.

用1602的i2c作为观察，x轴的数据做检验

接线与第一次不同的是，tx rx反接rx tx，gnd对接gnd

上次只是将数据传到了rx的串口，并没有变量控制

LZ 的台灯很有型 ，当然程序也不错，多谢了

一看标题,我以为是用操作系统了......
