Overview
The Ylc C++ library is a software controller for Yamano lenses | VS Technology lenses. These lenses provide control interface over serial port. The Ylc library inherits Lens interface. It includes source code of libraries: Lens interface library (provides interface and data structures to control lenses, Apache 2.0 license), Logger logging library (provides function to print log information in console and files, Apache 2.0 license) and SerialPort library (provides functions to work with serial ports, Apache 2.0 license). The Ylc library provides simple interface to be integrated in any C++ projects. The library repository (folder) provided by source code and doesn't have third-party dependencies to be specially installed in OS. It developed with C++17 standard and compatible with Linux and Windows.
