3.5 Building an HMI on the QEC-M-070T with 86Duino
This section will demonstrate how to build a basic HMI on the QEC-M-070T using the LVGL
library in the 86Duino Coding IDE 500+.
We assume that you have already completed the previous sections of the quick start guide,
including Package Contents, Hardware Configuration, Software Driver Installation, and Set up
the QEC-M-070T.
Instruction
LVGL (Light and Versatile Graphics Library) is a powerful open-source graphics library that
enables the creation of attractive and interactive graphical user interfaces (GUIs) for
embedded systems. By utilizing the LVGL library in combination with 86Duino IDE, developers
can design and implement HMIs with ease and efficiency.
You can expand and customize the HMI by utilizing other LVGL widgets such as buttons, sliders,
graphs, images, and more. LVGL provides a wide range of built-in widgets and customization
options to create sophisticated and visually appealing HMIs tailored to your specific
application.
