LVGL is a free and open-source graphics library providing everything you need to create embedded GUI with easy-to-use graphical elements, beautiful visual effects and low memory footprint.
I wish there is good training material out there to learn STM32...go ESP32! :)

Hi, do you have the SquareLine UI project? If so, can you share that information with me? I'm studying LVGL and SquareLine, this project will be much helpful to do mine. And in the git folder, there was no lv_port_stm_nucleo_g071rb.ioc file. Can you provide that information also? With the current version, I got an error while initializing the LCD. Thanks.

What's the use of saying that the product is certified? v8 LVGL port for stm32 is far from being complete or efficient. LVGL even decided to do not include STM32 in theirs latest v9 release .
@lvgl5 ай бұрын
It has multiple purposes: - Demonstrates that the device is capable enough to run a complex UI with a good performance - Let's you easily compare the performance of different devices - Allows the manufacturers to use the LVGL badge for marketing purpose We are waiting to start an official collaboration with ST to add support for their GPUs. I truly hope that it will happen soon.

We have used about 2x128kB buffer for rendering (2 x 1/6 screen size). While DMA sent the rendered image to the screen from one buffer, LVGL could render into the other buffer in parallel. If you want to lower memory usage, using 1/8 or 1/10 screen sized buffers also work with only a minor performance drop.
