硬件连接
连接指纹模块将 AS608 指纹模块与 Arduino 连接。通常AS608 使用 UART 接口进行通信。你需要将 AS608 的 TX、RX、VCC 和 GND 引脚分别连接到 Arduino 的相应引脚。
软件设置
安装必要的库 安装 Adafruit Fingerprint Sensor Library 打开 Arduino IDE进入库管理器Library Manager搜索 “Adafruit Fingerprint Sensor Library”然后点击安装。
编写代码
编写 Arduino 代码 导入必要的库 #include Adafruit_Fingerprint.h
#include SoftwareSerial.hSoftwareSerial mySerial(2, 3); // RX, TX
Adafruit_Fingerprint finger Adafruit_Fingerprint(mySerial);void setup() {Serial.begin(9600);while (!Serial); // For Leonardo/Micro/Zerodelay(100);Serial.println(\n\nAdafruit Fingerprint sensor enrollment);// set the data rate for the sensor serial portfinger.begin(57600);if (finger.verifyPassword()) {Serial.println(Found fingerprint sensor!);} else {Serial.println(Did not find fingerprint sensor :();while (1) { delay(1); }}
}void loop() {// Add your code here to enroll, delete, or search fingerprints
}录入指纹 uint8_t getFingerprintEnroll(uint8_t id) {int p -1;Serial.print(Waiting for valid finger to enroll as #); Serial.println(id);while (p ! FINGERPRINT_OK) {p finger.getImage();switch (p) {case FINGERPRINT_OK:Serial.println(Image taken);break;case FINGERPRINT_NOFINGER:Serial.println(.);break;case FINGERPRINT_PACKETRECIEVEERR:Serial.println(Communication error);break;case FINGERPRINT_IMAGEFAIL:Serial.println(Imaging error);break;default:Serial.println(Unknown error);break;}}// Convert image to templatep finger.image2Tz(1);switch (p) {case FINGERPRINT_OK:Serial.println(Image converted);break;case FINGERPRINT_IMAGEMESS:Serial.println(Image too messy);return p;case FINGERPRINT_PACKETRECIEVEERR:Serial.println(Communication error);return p;case FINGERPRINT_FEATUREFAIL:Serial.println(Could not find fingerprint features);return p;case FINGERPRINT_INVALIDIMAGE:Serial.println(Could not find fingerprint features);return p;default:Serial.println(Unknown error);return p;}// Store templatep finger.createModel();if (p FINGERPRINT_OK) {Serial.println(Prints matched!);} else if (p FINGERPRINT_PACKETRECIEVEERR) {Serial.println(Communication error);return p;} else if (p FINGERPRINT_ENROLLMISMATCH) {Serial.println(Fingerprints did not match);return p;} else {Serial.println(Unknown error);return p;}p finger.storeModel(id);if (p FINGERPRINT_OK) {Serial.println(Stored!);} else if (p FINGERPRINT_PACKETRECIEVEERR) {Serial.println(Communication error);return p;} else if (p FINGERPRINT_BADLOCATION) {Serial.println(Could not store in that location);return p;} else if (p FINGERPRINT_FLASHERR) {Serial.println(Error writing to flash);return p;} else {Serial.println(Unknown error);return p;}return true;
}删除指纹 void deleteFingerprint(uint8_t id) {if (finger.deleteModel(id) FINGERPRINT_OK) {Serial.println(Deleted!);} else {Serial.println(Could not delete);}
}查找指纹 void searchFingerprint() {uint8_t p finger.getImage();if (p ! FINGERPRINT_OK) return;p finger.image2Tz();if (p ! FINGERPRINT_OK) return;p finger.fingerFastSearch();if (p FINGERPRINT_OK) {Serial.print(Found ID #); Serial.print(finger.fingerID);Serial.print( with confidence of ); Serial.println(finger.confidence);} else {Serial.println(Did not find a match);}
}运行程序
运行 Arduino 程序 将代码上传到 Arduino 板并通过串口监视器查看输出。
这样你就可以在 Arduino 上控制 AS608 指纹识别模块实现指纹的录入、删除和查找功能。
