Hello all,
I have Dev a new pcb base on STM32h743IIT6 with the below hardware:
SDRAM: 256-W9825G6KH-6
FLASH : 25Q256JVEN
LCD: Module LCD tactile capacitif RGB IPS de 7 pouces from LCwiki buy on aliexpress
( it's a native rgb888 no driver )
Total Hardware around : 70 euro.
Here is the FMC and LTDC config:
SDRAM:
QSPI FLASH:
LTDC:
I have follow this post cube ide project https://github.com/JIU10/stm32h7_ltdc_dma2d/tree/master and it's work.
But now i am lost how to go further and i have some questions.
1 With the ltdc driver function below can i implement lvgl if yes how can i do if they are some link ?
2 What is the best option to make and interactive lcd panel.
2 I am coming from esp32 world so I want my st32 lcd would work like famous tftespi lib of Bodmer.

LVGL is not an ST implementation. You need to contact LVGL on their forums: https://forum.lvgl.io/

Hello,
You need to to find and read the LCD datasheet and refer to the application note AN4861 "Introduction to LCD-TFT display controller (LTDC) on STM32 MCUs" then adapt the LTDC parameters to the LCD specification or try to find if there was someone implemented it or provided its driver.

I have allready read AN4861 i am in this configuration
Figure 4. Display module without controller nor GRAM and with external framebuffer sdram
The lcd is working with ltdc driver function above now i am asking how to implement lvgl
