标题: Arduino制作的指纹锁(源程序Fingerprint Sensor library库)
先下载Fingerprint Sensor library运行库,解压库并放到arduino 运行库里，然后在arduino里样例里打开一个如下案例，
路径如下：
Example ->Adafruit_Fingerprint→fingerprint

  1. #include <Adafruit_Fingerprint.h>
  2. #include <SoftwareSerial.h>

  4. int getFingerprintIDez();

  6. // pin #2 is IN from sensor (GREEN wire)
  7. // pin #3 is OUT from arduino  (WHITE wire)
  8. SoftwareSerial mySerial(2, 3);


  11. Adafruit_Fingerprint finger = Adafruit_Fingerprint(&mySerial);

  13. void setup()
  14. {
  15.   Serial.begin(9600);
  16.   Serial.println("fingertest");

  18.   // set the data rate for the sensor serial port
  19.   finger.begin(57600);
  20.    
  21.   if (finger.verifyPassword()) {
  22.     Serial.println("Found fingerprint sensor!");
  23.   } else {
  24.     Serial.println("Did not find fingerprint sensor :(");
  25.     while (1);
  26.   }
  27.   Serial.println("Waiting for valid finger...");
  28. }

  30. void loop()                     // run over and over again
  31. {
  32.   getFingerprintIDez();
  33.   delay(50);            //don't ned to run this at full speed.
  34. }

  36. uint8_t getFingerprintID() {
  37.   uint8_t p = finger.getImage();
  38.   switch (p) {
  39.     case FINGERPRINT_OK:
  40.       Serial.println("Image taken");
  41.       break;
  42.     case FINGERPRINT_NOFINGER:
  43.       Serial.println("No finger detected");
  44.       return p;
  45.     case FINGERPRINT_PACKETRECIEVEERR:
  46.       Serial.println("Communication error");
  47.       return p;
  48.     case FINGERPRINT_IMAGEFAIL:
  49.       Serial.println("Imaging error");
  50.       return p;
  51.     default:
  52.       Serial.println("Unknown error");
  53.       return p;
  54.   }

  56.   // OK success!

  58.   p = finger.image2Tz();
  59.   switch (p) {
  60.     case FINGERPRINT_OK:
  61.       Serial.println("Image converted");
  62.       break;
  63.     case FINGERPRINT_IMAGEMESS:
  64.       Serial.println("Image too messy");
  65.       return p;
  66.     case FINGERPRINT_PACKETRECIEVEERR:
  67.       Serial.println("Communication error");
  68.       return p;
  69.     case FINGERPRINT_FEATUREFAIL:
  70.       Serial.println("Could not find fingerprint features");
  71.       return p;
  72.     case FINGERPRINT_INVALIDIMAGE:
  73.       Serial.println("Could not find fingerprint features");
  74.       return p;
  75.     default:
  76.       Serial.println("Unknown error");
  77.       return p;
  78.   }
  79.    
  80.   // OK converted!
  81.   p = finger.fingerFastSearch();
  82.   if (p == FINGERPRINT_OK) {
  83.     Serial.println("Found a print match!");
  84.   } else if (p == FINGERPRINT_PACKETRECIEVEERR) {
  85.     Serial.println("Communication error");
  86.     return p;
  87.   } else if (p == FINGERPRINT_NOTFOUND) {
  88.     Serial.println("Did not find a match");
  89.     return p;
  90.   } else {
  91.     Serial.println("Unknown error");
  92.     return p;
  93.   }  
  94.    
  95.   // found a match!
  96.   Serial.print("Found ID #"); Serial.print(finger.fingerID);
  97.   Serial.print(" with confidence of "); Serial.println(finger.confidence);
  98. }

  100. // returns -1 if failed, otherwise returns ID #
  101. int getFingerprintIDez() {
  102.   uint8_t p = finger.getImage();
  103.   if (p != FINGERPRINT_OK)  return -1;

  105.   p = finger.image2Tz();
  106.   if (p != FINGERPRINT_OK)  return -1;

  108.   p = finger.fingerFastSearch();
  109.   if (p != FINGERPRINT_OK)  return -1;
  110.    
  111.   // found a match!
  112.   Serial.print("Found ID #");
  113. Serial.print(finger.fingerID);
  114.   Serial.print(" with confidence of ");
  115. Serial.println(finger.confidence);
  116.   return finger.fingerID;
  117. }

你好，请问串口监视器中出现 did not Found fingerprint Sensor！该怎么解决呢
