无法使用lvgl显示ezip或者lvgl转换的bin

疑难解答
1

想使用lvgl做一个类似相册的应用，但是图片无论是使用lvgl官方转换成565的bin，还是使用思澈的工具转换为ezip的bin都无法显示，如果直接使用C文件倒是可以正常显示

显示关键部分代码如下

void image_show_update_image_bin(const void *bin_data)
{
    lv_img_set_src(main_obj->img, bin_data);
    lv_img_header_t header;
    lv_res_t res = lv_img_decoder_get_info(bin_data, &header);

    if (res == LV_RES_OK)
    {
        printf("Image width: %d\n", header.w);
        printf("Image height: %d\n", header.h);
        printf("Color format: %d\n", header.cf);
    }
    else
    {
        printf("Failed to get image info\n");
    }

}

使用ezip 的cmd命令如下

E:\Users\chen\Pictures\bmp\sdcard\Bin\1>ezip -convert 45.png -rgb565 -binfile 2 -lvgl_version 8
ezip version: 2.3.4_2025_07_04 Support_c_file

------------- ezip convert begin: ezip -convert 45.png color RGB565 -------------

next file:C:pictures/45.bin
Failed to get image info
Failed to get image info是上面代码打印的，这个是ezip的直接无法解析

prev file:C:pictures/test.bin
Image width: 355
Image height: 502
Color format: 4
这个是使用lvgl官方工具生成的565 true colour，能识别到bin类型，但是显示就是一片黑

无论如何都不能显示，不知道是哪里出了问题

我看你是生成了bin文件，我用agif例程改过。把png生成bin文件放在文件系统内，然后用lvgl显示出来。可以参考这个链接的第二个附件。相关代码如下：

图片1043×153 17.7 KB

3

你的sdk是日期是什么时候的

4

如果你用的是lvgl8的话，ezip图片路径就不加驱动器号，如果是lvgl9可能会需要更新一下sdk

5

我查看了我的版本是v2.4.0，此外我也尝试了使用去掉驱动器盘符，确实开始读取了，不知道哪里宏没配置好，直接崩溃了，但是我还不明白，为什么使用lvgl的工具生成的bin，能够解析文件大小格式，但是无法显示

报错如下

报错文件长这样，是不是我没开这个宏导致的，但是如果我打开会导致报错找不到一个app_mem.h文件，虽然上面有个好人给我提供的包里有这份头文件，但是添加了还会报其他宏错误

跟这个宏没什么关系，先测试一下是哪个文件导致错误的？

9

你是说测试一下代码上什么地方导致ezip报错吗

10

我看你这个日志上引起死机的应该是lvgl官方工具生成的那个，不知道是不是被错误识别成了特殊格式。方便提供工程代码和图片分析一下吗？

11

test.bin (244.7 KB)

ST07_sf32_SDcard_image_show.7z (7.0 MB)

提供了一个最简单的demo，和一个我生成的ezip.bin，文件是放置在sd卡根目录的photos/下面，使用的开发板的是类似黄山派的官方开发板，劳烦帮忙看一下

12

你这个图片是放置在sd卡中吗

13

能抽空帮我看一下吗，这个问题我确实不知道是什么原因，或者有能直接运行显示SD卡图片的demo也行

14

LVGL v8官方Example - SiFli SDK编程指南 文档
LVGL v9官方Example - SiFli SDK编程指南 文档

这两个例程都可以实现运行显示SD卡图片，menuconfig开启相关配置后修改src/main.c中的代码调用对应函数编译下载后可使用

image836×965 66.7 KB

15

你现在还能提供一下生成test.bin时使用的指令吗

16

example_v8.ezip (163.1 KB)或者试一下我提供的图片能不能正常工作

17

./ezip -convert ./gril.png -rgb565 -binfile 2 -lvgl_version 8
ezip version: 2.3.4_2025_07_04 Support_c_file

------------- ezip convert begin: ezip -convert ./gril.png color RGB565 -------------

---------------------------------------- ezip convert end !!! --------------------------------------
这个是我下午测试用的指令，大概上是这么写的，我试试你提供的文件

18

昨天下午测试了，demo确实可以使用sjpg格式，感谢提供支持，不过这个刷新速度有些慢，如果是ezip的有相关的示例吗，我看到这里面的ezip示例是C文件

19

你的sdk更新一下应该就行，ezip最近有过更改，旧的版本使用norflash的话没法处理其他介质上的ezip文件

20

或者我给你个文件替换一下sdk/middleware/lvgl/lv_drivers

lvsf_img_decoder.c (11.5 KB)
