ESP32 Forum

Hi there.

Recently I moved from arduino to Espressif framework within Platformio. Bigger difference, than I thought, and I am still learning. Now I am going to use my first color display (ST7789 driver), and wonder what way to go. LVGL seems to be the way. I just need a driver for the Espressif platform within Platformio. I have used U8G2 before with monochrome displays.

Here is seems like all drivers are out of date. lvgl_esp32_drivers are 3 years old, and aparently not suitable for newest framework and LVGL9. There seems to be some for Arduino, but I want to stick to the espressif. I have not been able to get anything to work.

I have read about the esp-bsp. Is that a way to go? I do not use a readymade board, hardware is my own. Can it be used with Platformio?

I also consider explorering the ESP-IDF by Espressif. Seems like there is a component manager, that can do some tricks, and it seems like support for ST7789 is present. Do I limit my selves using Platformio? Is there better support for color displays using the ESP-IDF?

What I could need, is a finger pointing in a direction to go. I am all over, and right now quite clueless, and find it hard to find out, what is deprecated and what is a maintained, and a wise way to go. Let me know, what libraries you use, with your color display, compatible with latest lvgl and latest framework.

Or is the driver actually included in the lvgl 9.1? I just can not get it to compile....

When using one of those 'new' cheap-yellow-displays, I just use the native st7789 driver and lvgl 9.x

Add lvgl and the esp_lvgl_port to your idf_component.yml and you can add the display after initializing spi by calling Edit: updated this example.

https://github.com/lvgl/lvgl_esp32_driv ... .0_idf_5.0 is a good reference to start with, although it is a little bit oudated and does not work on newer devices like ESP32C3, the functions and struct definitions are pretty much standard and can be copy-pasted to official examples, e.g. https://github.com/espressif/esp-idf/tr ... master/lcd.
