Description

Do we need to have framebuffer to be in the microcontroller ram or use display ram in display itself?

What MCU/Processor/Board and compiler are you using? PIC24

What LVGL version are you using? LATEST

What do you want to achieve?

Display on two screens

It shouldn’t matter, since LVGL provides you with the display content and you can copy it to the hardware in whatever manner necessary.

Take a look at the display porting guide. Unless you choose true double buffering mode, the buffer you provide to LVGL is just a working area. The final bitmap which reaches the display is copied by your driver, not LVGL.
