程序下载后看了一下，有些不明白的地方请教下楼主，取指针地址的函数： addr =(unsigned int)(y) * AP + x; 这个公式是怎么得到的？的确是这么用的，但在PDF文档里我没有找到这个公式。不明白这个公式。 还有在程序 locate_xy1 中写高8位为： write_dat((unsigned char)(addr >> 8)); //后写高八位 而在程序 locate_xy2 中写高8位为：write_dat((unsigned char)(addr >> 8) + basepart2); //后写高八位 多了一个basepart2，为每显示一行需要的字节数。 楼主能不能讲讲，，谢谢了。
