Overview

Slc C++ library is a software controller for Stingray SWIR lenses. The Slc library inherits Lens interfaces. The library has advanced auto focus functions. It depends on libraries: Lens (provides interface and data structures to control lenses, source code included, Apache 2.0 license), Logger (provides function to print logs, source code included, Apache 2.0 license), SerialPort (provides functions to work with serial ports, source code included, Apache 2.0 license), StingrayParser (provides functions to encode control commands and decode responses from Stingray lenses, source code included) and AFEngine (provides auto focus functions). The Slc 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.

Simple example

#include <chrono>
#include <iostream>
#include <string>
#include <thread>
#include "Slc.h"

int main(void)
{
    // Init lens controller.
    cr::lens::Lens* lc = new cr::lens::Slc();
    if (!lc->openLens("/dev/ttyUSB0"))
        return -1;

    // Get lens Zoom position
    std:: cout<< "Zoom pos: " <<
    lc->getParam(cr::lens::LensParam::ZOOM_POS) << std::endl;

    // Set Zoom speed to 10%.
    lc->setParam(cr::lens::LensParam::ZOOM_SPEED, 10);

    // Go to zoom position 10000 (Full tele).
    lc->executeCommand(cr::lens::LensCommand::ZOOM_TO_POS, 10000);

    // Show zoom movement (changing position).
    for (int i = 0; i < 50; ++i)

        std:: cout<< "Zoom pos: " <<
        lc->getParam(cr::lens::LensParam::ZOOM_POS) << std::endl;
        std::this_thread::sleep_for(std::chrono::milliseconds(100)); 
    }
    return 1;
