Clock

Objective The course will show you how to use Processing to display a Microduino clock. Equipment Microduino-Core Microduino-FT232R Microduino-RTC Other Hardware Equipment A USB cable Schematic Just stack the three Microduino modules needed together Program Referring to ProcessingColock MicroduinoColock Debugging Step 1: Build the hardware environment on the basis of the schematic, as follows: Step 2: Here the code needed: The code of the two ends (Processing and Microduino) Microduino: //Just run the RTC module and transmit time data to the serial port 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()); } //Initialize time //initial 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: //Define the first serial data after getting it, and cache it if there is a new line // 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); //Initialize the center point position of the clock as well as the length of the hour hand, minute hand and the second hand 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 ; //Draw the current value after getting the x-coordinate value of the mouse via serial output void update(int x) { port.write(x); stroke(255); line(mouseX, 0, mouseX, 160); text (mouseX, mouseX, 180); } //Receive the serial data and process time information //split data by ":" String time[]=val.split(":"); //if some exception happend, initial time is 0 clock 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; } //Draw a clock 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 clock 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); } Step 3: Download the code and get it complied successfully. Step 4: Focus on Processing after the system goes well. Result A running clock will be displayed on the screen, just like this Video
