Jay-D Arduino Uploading Code

After setting everything up, we can move on to uploading code to your Jay-D.

Choose what to upload

You can either write your own simple program or download one of the games from our Github repository to use as a starting point. 

Here's an example of a simple code you can upload:

#include <JayD.h>
Display* display;
Sprite* sprite;
 
void setup() {
  JayD.begin();
  display = &JayD.getDisplay();
  sprite = display->getBaseSprite();
  pinMode(PIN_BL, OUTPUT);
  digitalWrite(PIN_BL, LOW);
  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);
}

Let's make sure your Jay-D is ready for the upload!

Turn on your Jay-D and plug it into your computer with a USB cable. 
Next, in Arduino go to Tools -> Port, and select the port your Jay-D is connected to. It’s usually the only option available.

Then, click the Upload button (arrow pointing to the right).

And that's it! You have now uploaded your code to the Jay-D. Great job!
