課程報告時順便做的一個小玩意

單片機源程序如下:
  1. int pulsePin = A0;                 // Pulse Sensor purple wire connected to analog pin 0
  2. int blinkPin = 12;                // pin to blink led at each beat
  3. int fadePin = 13;                  // pin to do fancy classy fading blink at each beat
  4. int fadeRate = 0;                 // used to fade LED on with PWM on fadePin
  5. // these variables are volatile because they are used during the interrupt service routine!
  6. volatile int BPM;                   // used to hold the pulse rate
  7. volatile int Signal;                // holds the incoming raw data
  8. volatile int IBI = 600;             // holds the time between beats, must be seeded!
  9. volatile boolean Pulse = false;     // true when pulse wave is high, false when it's low
  10. volatile boolean QS = false;        // becomes true when Arduoino finds a beat.

  12. #include "U8glib.h"
  13. U8GLIB_SSD1306_128X64 u8g(5, 4, 6, 2, 3);  // SW SPI Com: SCL = 5,SDA = 4,CS = 6,RST = 3,DC = 2
  14. const uint8_t rook_bitmap[] PROGMEM = {

  16.   0x00,         // 00000000
  17.   0x55,         // 01010101

  29.   interruptSetup();                 // sets up to read Pulse Sensor signal every 2mS
  30.   // UN-COMMENT THE NEXT LINE IF YOU ARE POWERING The Pulse Sensor AT LOW VOLTAGE,
  31.   // AND APPLY THAT VOLTAGE TO THE A-REF PIN
  32.   //analogReference(EXTERNAL);
  33.   u8g.setColorIndex(1);         // pixel on
  34. }

  36. void loop() {
  37.   u8g.firstPage();
  38.   do {
  39.     draw();
  40.   } while ( u8g.nextPage() );
  41.   sendDataToProcessing(' ', Signal);     // send Processing the raw Pulse Sensor data
  42.   if (QS == true) {                      // Quantified Self flag is true when arduino finds a heartbeat
  43.     fadeRate = 255;                  // Set 'fadeRate' Variable to 255 to fade LED with pulse
  44.     sendDataToProcessing(',', BPM);  // send heart rate with a 'B' prefix
  45.     sendDataToProcessing(',', IBI);  // send time between beats with a 'Q' prefix
  46.     QS = false;                      // reset the Quantified Self flag for next time
  47.   }
  48.   ledFadeToBeat();
  49.   delay(20);                             //  take a break
  50. }

  56.   if (QS) {
  57.     u8g.drawBitmapP( 40, 40, 1, 8, rook_bitmap);
  58.   }
  59.   u8g.drawStr( 10, 20, "BPM");
  60.   u8g.setPrintPos(80, 20);
  61.   u8g.print(BPM);
  62. }
  63. void ledFadeToBeat() {
  64.   fadeRate -= 15;                         //  set LED fade value
  65.   fadeRate = constrain(fadeRate, 0, 255); //  keep LED fade value from going into negative numbers!
  66.   analogWrite(fadePin, fadeRate);         //  fade LED
  67. }


  70. void sendDataToProcessing(char symbol, int data ) {
  71.   Serial.print(symbol);                // symbol prefix tells Processing what type of data is coming
  72.   Serial.println(data);                // the data to send culminating in a carriage return

沒有#include "U8glib.h"，無法使用
