Creating a simple program

After creating a new empty PlatformIO project you're ready for the next step.

Preparation

The PlatformIO project structure consists of the following:

• platformio.ini (Project Configuration File)
• src directory where you should place source code (*.h, *.c, *.cpp, *.S, *.ino, etc.)
• lib directory can be used for the project-specific (private) libraries Now, you need to download the necessary libraries and configuration files from our GitHub repository and place them in your project directory.

Writing a simple program

We're now going to write a simple program. Here's a quick example:

#include <Arduino.h>
#include <Nibble.h>

Display* display;
Sprite* sprite;

void setup() {
  Nibble.begin();

  display = Nibble.getDisplay();
  sprite = display->getBaseSprite();
  sprite->clear(TFT_BLACK);
  sprite->setTextColor(TFT_WHITE);
  sprite->setTextFont(2);
  sprite->setCursor(0,0);
  sprite->print("Hello World!");
  display->commit();
}
void loop() {
  delay(1000);
}

Next steps

Turn on your Nibble and plug it into your computer with a USB cable.Click the Upload button on the bottom left part of the screen (arrow pointing to the right).

You have now uploaded your code on the Nibble!
