V8 display driver (double buffer) low FPS & high CPU

[gianlucacornacchia]

Hi @kisvegabor,
what I try to achive is full_refresh=0 and direct_mode=1, like you suggested in a previous post:

@kisvegabor

However, in the flush_cb you can mimic v7’s behavior like this:

1. Set 2 full screen buffer with full_refr = 0, direct_mode = 1 ​
2. In flush_cb check if lv_disp_flush_is_last(drv) == true
3. If so, copy the areas:

my_set_active_buffers(color_p);
lv_disp_t* disp = _lv_refr_get_disp_refreshing();
for(i = 0; i < disp->inv_p; i++) {
   ​if(disp->inv_joined[i]) continue;
 ​
 ​  my_copy_area(disp->inv_areas[i]);
}

many thanks for the reply,
gianluca
