I have a FINGERPRINT SENSOR shield: Fingerprint sensor : ID 751 : $49.95 : Adafruit Industries, Unique & fun DIY electronics and kits
I need a code by which I can get 255 HEX values ??fingerprint console, without writing it to the database and read from there.
So I put a finger - and Serial port is transmitting 255 HEX digit finger hash.
I have not found in the standard library functions Adafruit_Fingerprint.cpp
The library has a function to record only the imprint of the database FINGERPRINT SENSOR, and then get him out of there.
And I for the project should be done comparing 255 HEX digit finger hash with the value of the variable in the arduino (and not from memory FINGERPRINT SENSOR), but to begin to implement it,
I can not programmatically display 255 HEX digit hash finger without writing it into memory FINGERPRINT SENSOR, but just on the screen through the serial
If this can be realized, tell me how.
