I’m starting with LVGL and I read part of documentation on site web but I’ve some question about use of external FLASH and SDRAM.
I’m using a STM32 kit STM32F769I-Discovery, it has one FLAH of 512Mbit and SDRAM of 128Mbit. My questions are:
When we create a new display is necessary to store it on buffer and in general if we use a buffer the same size screen resolution whit a good color depth (e.i 32 bits) we need to use SDRAM external on Cortex-M so is there any chance to tell LVGL that create screen on external RAM.
If we create new object it will be storage on microcontroller internal RAM I suppose, so Is there a possibility to allocated the pointer object on SDRAM external.
if we need add image to our protect I think that best way is using external FLASH of board, where can we configure this option on LVGL to it’s looking for to FLASH.
Sorry if I worng in some concept of LVGL.
