Use Littlevgl Lib To Display Rgb888 3 Bytes Issue 211 Lvgl Lvgl Github In your disp flush function you can "compress" the bytes of the color buffer to skip the alpha bytes before sending them to the display frame buffer. however the color buffer is a const variable you can edit it without an worry. If lvgl set px cb 24bit is set then the rendered image is already in rgb888 format. but note that it can be much faster to convert only the result image than every pixel.
Wrong Color Display With Lvgl 8 3 General Discussion Lvgl Forum When setting up the buffers for rendering (lv display set buffers()), make the buffer 8 bytes larger. this is necessary because lvgl reserves 2 x 4 bytes in the buffer, as these are assumed to be used as a palette. Micropython binding for littlevgl (lv binding micropython) was designed to make it simple to use littlevgl with micropython. it plays as a bridge between micropython and lvgl libraries. Hi, rgb888 is already supported in the master branch (v9 development). you just need to set lv color depth 24 in lv conf.h. This tutorial describes how i got littlevgl working on a small 128x64 oled display with a pic24fj microcontroller. the oled display board i used had a sh1106 driver chip, but the code would probably work nealry unchanged with an ssd1306, and should be easily adaptable to other display drivers.

This guide is intended to be a step by step instruction of how to configure the stm32cube hal with the new tft lcd display drivers introduced in lvgl v9.0. the example code has been tested on the stm32f746 based nucleo f746zg board with an st7789 based lcd panel connected via spi. I implemented a minimal and hacky rgb888 support in feat rgb888 branch. it is useful because: ili9488 doesn't support rgb565 only rgb666 format packet into 3 bytes. rgb888 can be used directly in this case. (now a conversation is required) it can be tested by setting lv color depth 24 in lv conf.h. Embedded graphics library to create beautiful uis for any mcu, mpu and display type. lvgl lvgl.h at master · lvgl lvgl. The following steps show how to setup littlevgl on an embedded system with a display and a touchpad. you can use the simulators to get ‘ready to use’ projects which can be run on your pc.
