Finger Print Unit (FPC1020A)
SKU: U008
FINGER Unit is a fingerprint sensor. This all-in-one fingerprint sensor makes fingerprint adding,verification,mananging super simple.
Uart protocol, Compact size and ultra-low power consumption makes it very attractive to use around M5Stack series product. it performs fast fingerprint matching with highest security level and optimal user convenience. You can program to set the fingerprint recognition comparison level and different security level . if you ever consider secure your project with biometrics,don't forget to include this M5unit FINGER.
This unit cummunicate with M5Core by UART protocol connected via PORTC UART settings:
· Baudrate(default: 19200bps) · Start bits(1 bit) · Stop bits(1 bit) · Parity(no)

// initialization M5.begin(); Serial2.begin(19200, SERIAL_8N1, 16, 17); userNum = fpm_getUserNum(); M5.Lcd.print("userNum:"); M5.Lcd.println(userNum);

// add a new user res1 = fpm_addUser(userNum,1); //get function result

// compare your finger res1 = fpm_compareFinger();

// delete all user res1 = fpm_deleteAllUser();
