如果显示乱码，一般和取模方向有关

显示其他字符是否正常

仔细看了下显示图片的子程序，觉得和我手头上所用HD529M1型号的12864很象，便复制整个程序到我的开发板里试了试，显示果然是乱糟糟的：

反复试了几次，还是不行，静下心来读程序，终于发现小问题，水平地址0x30有误，应该分别改为0x80和0x88，一切OK：

这几天研究12864的心得就是：有12864的问题要问，一定要给出具体型号，不然就只能自己查找资料，别人没用过的话很难帮上忙。换句话说，学习的话一定要用大众型号的12864，或者对着手头例程买。
我的12864是好多年前朋友送的，一直吃灰中，疫期期间出不去，翻出来玩玩，好在坛子里找到了例程。

你好，我的图片一直左右颠倒了，但是明明用的图形取模正常，请问您的图片取模是什么取模方向呢？
