标题: MEGA2560主控自行车骑行监测器源码
自行车骑行监测器，可以GPS定位，检测骑行速度，检测心率，同时将以上数据写入SD卡内进行保存，使用MEGA2560主控
SD卡的SPI接口 ** MOSI - pin 51 ** MISO - pin 50 ** CLK  - pin 52 ** CS   - pin 53

GPS的串口使用mega2560的串口1  Serial 1: Pin19 (RX) and Pin18 (TX);Pin13接一个LED显示GPS是否工作正常

两个霍尔传感器接在外部中断  Pin2 (interrupt 0), Pin3 (interrupt 1)

心跳指示灯在 Pin5   int fadePin = 5
int blinkPin = 14;               


单片机源程序如下:
  1. //#include"Arduino.h"
  2. //#include "AllSerialHanding.h"
  3. //#include "Interrupt.h"
  4. //#include "SD_ReadWrite.h"
  5. #include "all.h"
  6. #define PROCESSING_VISUALIZER 1
  7. #define SERIAL_PLOTTER  2
  8. volatile int BPM;                   // int that holds raw Analog in 0. updated every 2mS
  9. volatile int Signal;                // holds the incoming raw data
  10. volatile int IBI = 600;             // int that holds the time interval between beats! Must be seeded!
  11. static int outputType = SERIAL_PLOTTER;
  12. String beat_data = " BPM:0 IBI:0 Signal:0";

  14. void PulseSensor_SD_Write()
  15. {
  16.   SD_Write("test.txt",beat_data);  //脉冲数据写入SD卡中PulseSensor.txt文件
  17. }
  18. //  Sends Data to Pulse Sensor Processing App, Native Mac App, or Third-party Serial Readers.
  19. void sendDataToSerial(char symbol, int data ){
  20.     Serial.print(symbol);
  21.     Serial.println(data);
  22.   }

  36.

  38.     default:

  42. }

  48.       sendDataToSerial('B',BPM);   // send heart rate with a 'B' prefix
  49.       sendDataToSerial('Q',IBI);   // send time between beats with a 'Q' prefix
  50.       break;

  52.     default:
  53.       break;
  54.   }
  55. }

  57. // SET THE SERIAL OUTPUT TYPE TO YOUR NEEDS
  58. // PROCESSING_VISUALIZER works with Pulse Sensor Processing Visualizer
  59. //      https://github.com/WorldFamousElectronics/PulseSensor_Amped_Processing_Visualizer
  60. // SERIAL_PLOTTER outputs sensor data for viewing with the Arduino Serial Plotter
  61. //      run the Serial Plotter at 115200 baud: Tools/Serial Plotter or Command+L

  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.   }
