Treehopper C++ API
Windows

Prerequisites

The only currently-supported toolchain on Windows is the MSVC-based one found in Visual Studio 2017.

Cygwin and MinGW-based build environments are not supported, so while you can use IDEs such as JetBrain's CLion for development, you must build your projects using the MSVC compiler.

Building the library

Treehopper's C++ API is not distributed in binary form; you will need to build it before including and linking to your project.

Using vcpkg

The recommended way of obtaining Treehopper's C++ API is with Microsoft's open-source vcpkg tool, a C/C++ library manager that will automatically download, build, and install packages to your system. Vcpkg contains more than 900 different commonly-used C/C++ packages.

Installing Vcpkg

If you do not already have Vcpkg installed, clone or download the vcpkg repo. Here, we'll assume you cloned to C:\src\vcpkg.

Then, build the vcpkg executable:

C:\src\vcpkg> .\bootstrap-vcpkg.bat

Finally, integrate vcpkg into Visual Studio:

C:\src\vcpkg> .\vcpkg integrate install

Installing Treehopper's C++ API

Treehopper and Treehopper.Libraries are distributed in a single treehopper package that you can install:

C:\src\vcpkg> .\vcpkg install treehopper

By default, this will build an x86 library. If you want to target x64, execute

C:\src\vcpkg> .\vcpkg install treehopper:x64-windows

Manually using CMake

If you do not wish to use vcpkg, you can manually clone Treehopper's repo, open the C++ folder from Visual Studio 2017, and build the project collection. This will result in a .dll and .lib file for use in your projects.

Blinky

Create a new Visual C++ Windows Console application in Visual Studio 2017. Replace the contents of the main file with the following code:

// main.c
#include <Treehopper/ConnectionService.h>
#include <chrono>
using namespace Treehopper;
using namespace std::chrono;
int main()
{
board.connect();
for (int i = 0; i<20; i++)
{
board.led(!board.led());
this_thread::sleep_for(milliseconds(100));
}
board.disconnect();
return 0;
}

This code will get a reference to the first board found connected to the system, connect to it, and blink the LED 20 times before disconnecting and exiting.
