Overview

We recommend using our UI library, KGFX, for common graphics use cases on kublet. Install our library by including this line in your platform.ini file:

lib_deps = 
  kublet/KGFX@^0.0.22

You can find the latest version of KGFX by searching the KGFX library on PIO or here.

To initialize KGFX in your project and begin using its APIs, you should have these declarations in your main.cpp file:

#include <kgfx.h>

KGFX ui;

void setup() {
  ui.init();
  ui.clear();

  // Call KGFX APIs
}

void loop() {
  delay(1);
}

We call clear() after we initalize the library just in case there are leftover pixels from the previous app.

KGFX is a wrapper around the TFT_eSPI library. We are constantly adding new functions as needed. However, if there are functions that are not yet available on KGFX, feel free to submit a PR or build your own functions on top of KGFX.
