Hi all i have been working with LTDC module inside stm32 MCUs to drive an external parallel 24 bit RGB display ,
i integrated an LVGL UI inside this project but my output is kinda look like this
i dont know what is causing it , . display is running at 11 mhz.
i am using nucleo H7A3ZI-q dev board with cortex M7
i asked in lvgl no response from them :sad_but_relieved_face: any help here
i also tried to fill iw with two colors 50-by 50 theni got this
so i think that problem is not with LVGL .
<<<<<<<<<<<<update>>>>>>>>>>>>>>>>>>>
i was able to get this output bu changing the startaddress from
if i put 0x24000000 i get the misaligned one . but now the issue is if i integrate LVGL now while the startaddress is (uint32_t)framebuffer , i get nothing in display , if i chnage that to 0x24000000 i get the misaligned output of LVGL
