Description
Hey, I've had the Arduino Giga Display for a few days now.
I'm trying to get it to work with the LVGL example.
I have created a screen with two buttons. The screen is scrollable.
When I scroll the screen, there is a tearing effect.
I would like to eliminate the tearing effect.
I have already enlarged the buffer and added a double buffer.
lv_conf.h
#define LV_MEM_SIZE (256U * 1024U)
Arduino_H7_Video.cpp
static lv_color_t * buf2;
buf1 = (lv_color_t*)malloc((width() * height() / 4) * sizeof(lv_color_t));
buf2 = (lv_color_t*)malloc((width() * height() / 4) * sizeof(lv_color_t));
lv_disp_draw_buf_init(&draw_buf, buf1, buf2, width() * height() / 4);
I have also activated the DMA2D (aka Chrom Art) GPU.
lv_conf.h
#define LV_USE_GPU_STM32_DMA2D 1
#if LV_USE_GPU_STM32_DMA2D
/*Must be defined to include path of CMSIS header of target processor
e.g. "stm32f769xx.h" or "stm32f429xx.h"*/
#define LV_GPU_DMA2D_CMSIS_INCLUDE <stm32h747xx.h>
#endif
What else can i do to eliminate the tearing effect?
