Hello,

thanks for the Tip. I’M changig it. First after compiling, the Compiler miss the core_cm7.h. After changing the Include-Path, the Program compiled without erros. But the Screen looks bad.

My Display Flush:

void disp_flush(lv_disp_drv_t * disp_drv, const lv_area_t * area, lv_color_t * color_p)
{
int32_t x;
int32_t y;
LCD_SetWindows(area->x1, area->y1, area->x2, area->y2);
LCD_WR_REG(0x2C00);
LCD_WR_REG(0x3C00);
for(y = area->y1; y <= area->y2; y++) {
for(x = area->x1; x <= area->x2; x++) {
/* Put a pixel to the display. For example: */

    	LCD->LCD_RAM =color_p->full;
        color_p++;
    }
}

lv_disp_flush_ready(disp_drv);

}
