Christian Dupaty / Mbed OS R503_fingerprint_HelloWorldV4

Library for fingerprint R503 Adaptation from Arduino Library

Dependencies:   Fingerprint-Lib

This a library and demo for fingerprint R503

For datasheet, see here -> https://cdn-shop.adafruit.com/product-files/4651/4651_R503%20fingerprint%20module%20user%20manual.pdf

This is an adaptation of Adafruit library (Arduino) to ARM MBED, tested on NUCLEO L073RZ

For this exemple default connexions on NUCLEOL073RZ are :

TX <-> PC_0

RX <-> PC_1

WAKEUP <-> PB_0 , this is an Interrupt , you must connect a pull-up resistor (4K to 15k) between WAKEUP and DC3.3v

Power Supply 3.3v on Arduino connector

3.3VT : 5v on Arduino connector

IMPORTANT !!! There ara yet some bugs with communications UART
