目的

本教程将教大家如何用processing来显示Microduino时钟。

设备

  • 其他硬件设备
    • USB数据连接线 一根

原理图

堆叠设备说明中的三个Microduino模块即可

程序

ProcessingColock

MicroduinoColock

调试

步骤一:按着原理图搭建硬件环境,像这样:

ProcessingColockConnectionDiagram.jpg


步骤二:解释一下代码:

本例需要两端的代码,Processing端和Microduino端

Microduino:

//运行RTC,并输出时间数据到串口

 void loop()
 {
   rtc.formatDate();
   rtc.formatTime();
   //send time data to port
   Serial.print(rtc.getHour());
   Serial.print(":");
   Serial.print(rtc.getMinute());
   Serial.print(":");
   Serial.println(rtc.getSecond());
 }

//初始化时间

 //inital time
 void vosettime()
 {
   //rtc.initClock();
   //day, weekday, month, century(1=1900, 0=2000), year(0-99)
   rtc.setDate(4, 1, 6, 0, 14);
   //hr, min, sec
   rtc.setTime(15, 28, 50);
 }

Processing:

//得到第一个串口的数据,并定义如果有换行就缓存

 // List all the available serial ports in the output pane.
 // You will need to choose the port that the Wiring board is
 // connected to from this list. The first port in the list is
 // port #0 and the third port in the list is port #2.
 println(Serial.list());
 // Open the port that the Wiring board is connected to (in this case #0)
 // Make sure to open the port at the same speed Wiring is using (9600bps)
 port = new Serial(this, Serial.list()[0], 9600);


//初始化钟表圆心位置,时针,分针,秒针的长度

 int radius = min(width, height)/2;
 secR = radius * 0.72;
 minR = radius * 0.60;
 hourR = radius * 0.50;
 clockDiameter = radius * 1.8;
 cx = width /2 ;
 cy = height /2 ;

//串口输出鼠标x坐标值,并绘制当前值

 void update(int x) 
 {
   port.write(x);
   stroke(255);  
   line(mouseX, 0, mouseX, 160);   
   text (mouseX, mouseX, 180);
 }


//接收串口数据,处理时间信息

   //split data by ":"
   String time[]=val.split(":"); 
   //if some exception happend, initial time is 0 colock
   try {
     hour=Integer.parseInt(time[0]);
     minute=Integer.parseInt(time[1]);
     second=Integer.parseInt(time[2]);
   } 
   catch (NumberFormatException e) {
     hour=0;
     minute=0;
     second=0;
   }

//绘制钟表

   float s = map(second, 0, 60, 0, TWO_PI) - HALF_PI;
   float m = map(minute+norm(second, 0, 60), 0, 60, 0, TWO_PI)- HALF_PI;
   float h = map(hour+norm(minute, 0, 60), 0, 24, 0, TWO_PI * 2 ) - HALF_PI;
   //draw colock
   stroke(255, 250, 0);
   strokeWeight(1);
   line(cx, cy, cx + cos(s) * secR, cy + sin(s) * secR);
   strokeWeight(2);
   line(cx, cy, cx+ minR * cos(m), cy + minR * sin(m));
   strokeWeight(4);
   line(cx, cy, cx + hourR * cos(h), cy + hourR * sin(h));
   strokeWeight(2);
   stroke(255, 0, 0);
   for (int a = 0 ;a<360;a+=6) {
     float angle =  radians(a);
     float cx1 =  (secR+20) * cos(angle);
     float cy1 =  (secR+20) * sin(angle);
     point(cx + cx1, cy + cy1);
     if (a%30==0) {
       line(cx+cx1, cy+cy1, cx+cx1*0.98, cy+cy1*0.98);
       fill(255);
       int mark;
       if (a/30>9) {
         mark = a/30 -9;
       }
       else
       { 
         mark = a/30 +3;
       }
       text(mark, cx+cx1*1.05-5, cy+cy1*1.05+5);
     }
     fill(90, 155, 11);
     text(hour+":"+minute+":"+second, cx-25, cy+100);
     text("Microduino", cx-25, cy-100);
   }

步骤三:下载代码并编译通过。

步骤四:运行后,看看processing中会出现什么。

结果

屏幕上会显示一个运转的时钟,像这样
