Device interface library for multiple platforms including Mbed.
Dependents: DeepCover Embedded Security in IoT MaximInterface MAXREFDES155#
Maxim Interface is a library framework focused on providing flexible and expressive hardware interfaces. Both communication interfaces such as I2C and 1-Wire and device interfaces such as DS18B20 are supported. Modern C++ concepts are used extensively while keeping compatibility with C++98/C++03 and requiring no external dependencies. The embedded-friendly design does not depend on exceptions or RTTI.
