怎么样，把GUI去掉后，能够驱动spi lcd(ST7789)显示一张已经放在PSRAM的"RGB565.bin"的图片？启动GUI占用太多内存资源，我们玩具类产品，显示眼睛，完全不用GUI。

你好，正常初始化屏幕后，按照下面的方法(放入cp1侧)，直接将解码后的图片起始指针disp_buf传入void lcd_frame_buffer_flush(uint8_t *disp_buf)

Code: Select all

#include "driver/media_types.h"
#include <frame_buffer.h>
#include "yuv_encode.h"

static frame_buffer_t *lvgl_frame_buffer = NULL;

static void lvgl_frame_buffer_free(frame_buffer_t *frame_buffer)
{
    //To do
}

const frame_buffer_callback_t lvgl_frame_buffer_cb =
{
    .free = lvgl_frame_buffer_free,
};

void lcd_frame_buffer_init(UINT16_T lcd_width/*屏幕宽*/, UINT16_T lcd_height/*屏幕高*/)
{
    lvgl_frame_buffer = tkl_system_psram_malloc(sizeof(frame_buffer_t));
    if (!lvgl_frame_buffer) {
        bk_printf("%s %d lvgl_frame_buffer malloc fail\r\n", __func__, __LINE__);
        return ret;
    }
    memset(lvgl_frame_buffer, 0, sizeof(frame_buffer_t));
    lvgl_frame_buffer->width = lcd_width;
    lvgl_frame_buffer->height = lcd_height;
    lvgl_frame_buffer->fmt = PIXEL_FMT_RGB565;
    lvgl_frame_buffer->cb = &lvgl_frame_buffer_cb;
}

void lcd_frame_buffer_flush(uint8_t *disp_buf)
{
	lvgl_frame_buffer->frame = (uint8_t *)disp_buf;
	lcd_display_frame_request(lvgl_frame_buffer);
}
