# Sample C++ app for Epsilon

[![Build](https://github.com/numworks/epsilon-sample-app-cpp/actions/workflows/build.yml/badge.svg)](https://github.com/numworks/epsilon-sample-app-cpp/actions/workflows/build.yml)



This is a sample C++ app to use on a [NumWorks calculator](https://www.numworks.com).

```cpp

using namespace EADK;

void eadk_main() {

  Display::pushRectUniform(

    Display::Rect(0, 0, 320, 240),

    Display::Color(0x000000)

  );

  while (1) {

    Keyboard::State kbd = Keyboard::scan();

    if (kbd.keyDown(Keyboard::Key::OK)) {

      spaceship.createRockets();

    }

    if (kbd.keyDown(Keyboard::Key::Up)) {

      spaceship.move(0, -Spaceship::k_step);

    }

    refreshScene();

  }

}

```

## Build the app

To build this sample app, you will need to install the [embedded ARM toolchain](https://developer.arm.com/Tools%20and%20Software/GNU%20Toolchain) and [Node.js](https://nodejs.org/en/). The C SDK for Epsilon apps is shipped as an npm module called [nwlink](https://www.npmjs.com/package/nwlink) that will automatically be installed at compile time.

```shell

brew install numworks/tap/arm-none-eabi-gcc node # Or equivalent on your OS

make

```

You should now have a `target/voord.nwa` file that you can distribute! Anyone can now install it on their calculator from the [NumWorks online uploader](https://my.numworks.com/apps).

## Run the app locally

To run the app on your development machine, you can use the following command

```shell

# Now connect your NumWorks calculator to your computer using the USB cable

make run

```
