Abstract

The objective of this work is the development of a set of tools to help in the design of a GUI on a touch-screen connected to a microcontroller, specifically an ESP32. The set of tools contains the necessary templates for the location and configuration of the different elements that make up the interface, such as polygons, editable text boxes, labels, check-boxes, button-radio and buttons. For responsive elements, it also allows the definition of the type of interaction with the user: call-back functions, modified variables or entered texts. To facilitate the tedious task of designing an interface, a library has been developed for desktop projects, which can be compiled and debugged on a PC or Laptop and which allows testing 95% of the interface's functionalities, but using a much faster and more comfortable development environment.
