我在做24bit的图片试验时，定义了6张图片,运行时第四张图片的下半部分开始有花点？

我在做24bit的图片试验时，一共定义了6张24位的图片，结果程序可以运行，但是第四张图片的下半部分开始有花点，更换图片的编译顺序后，发现放在前面的三张总是正常的，可是后三张就出现花点，图片我是用image2lcd软件转的，而且为了方便我转成32位的了，哪位能帮在下解决一下，谢谢啦！还有一点就是如果只定义三张图片，那么无限循环地显示都不会出错的.

请将代码帖出来，我来参考一下。

你最好先使用一张图片试一下，如果还是出现了那花屏，可能是你转的32位不行，就要先转成24位后再看。如果没出现花屏的话，你可以搜索一下论坛上的帖子，有关于它的解决方法。

代码：
主函数图片显示循环
while(1)
{
  Paint_Bmp(0, 0, 320, 240, gImage_logo1);
  Delay(500);   
  Paint_Bmp(0, 0, 320, 240, gImage_logo2);
  Delay(500);  
  Paint_Bmp(0, 0, 320, 240, gImage_logo3);
  Delay(500);
  Paint_Bmp(0, 0, 320, 240, gImage_logo4);   
  Delay(500);
  Paint_Bmp(0, 0, 320, 240, gImage_logo5);
  Delay(500);  
  Paint_Bmp(0, 0, 320, 240, gImage_logo6);

文件的编译顺序：

六个logoX文件对应六张24bit的图片数组，按照这个顺序编译的话logo4、5、6对应的图片出错，总之就是放在后面的三张就出错。

三张及三张以下不会出错，麻烦两位版主了，先谢谢了！

bin文件大于1M了，记得要修改一个参数

ls，请问大于1M要改什么参数？我也面临这个问题

请问楼主怎么解决的。我也是这个问题

请问楼主怎么解决的。我也是这个问题

解决办法就是这个

把U32 size = 0x200000,这么大就足够放下十张照片了
