Sample C++ app for Epsilon

This is a sample C++ app to use on a NumWorks calculator.

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 and Node.js. The C SDK for Epsilon apps is shipped as an npm module called nwlink that will automatically be installed at compile time.

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.

Run the app locally

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

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