Can I implement LVGL on STM32H743IIT6 with a custom LCD 1024 x 600 HD

[KNaim.1]

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.

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

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