tlyp 3:27e027ab268b 33 * @brief This is the header file used for the MAX30208 human body temperature sensor library.
tlyp 3:27e027ab268b 34 * @version 1.0
tlyp 3:27e027ab268b 35 * @notes This file needs to be imported along with MAX30208.cpp for the program to work properly. This is library containing basic functions to be used in conjunction with the MAX30208. This library does not support any other devices. This is an MBed tested library.
