Library for fingerprint R503 Adaptation from Arduino Library
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
