With the increasing popularity of smart home and wearable devices, demand for intuitive graphical user interfaces (GUIs)is increasing. However, if you're engaged in embedded device development, rather than Android/iOS, GUI development may take a lot of effort. As an open-source embedded graphics library, LVGL has become increasingly popular. LVGL has been adapted to mainstream embedded platforms such as NXP, STM32, PIC, Arduino, and ESP32. It has a very small memory footprint: 64 kB flash and 8 kB RAM is enough to make it work, and it can run smoothly on various Cortex-M0 low-power MCUs. LVGL supports input types such as touchscreen, mouse and buttons and contains more than 30 controls, including TileView suitable for smart watches. The MIT license it chose doesn’t restrict enterprise and commercial use. Our teams’ feedback on this tool has been positive and one of our projects using LVGL is already in production, more specifically in small batch manufacturing.
