我原来用汇编语言做了一个19264向左滚动显示的。估计程序对你有点不适用。

滚动显示的硬件：1、ks0108控制器的LCD（楼主的可以）
                        2、根据显示内容的数据量，应有足够的RAM，如片内不足，可以外挂。
编程的思路是（滚动显示内容不固定）：将要滚动显示的汉字字模先逐字节读出再写入RAM暂存，汉字上下部分分别读写（RAM块的分配根据自己的情况，）。然后送显示，每扫描一遍（或N遍，根据滚动的速度要求，来确定N）“显示子程序”送显示的数据在RAM中的首地址加1，尾接头顺序循环送显示。
      不知道你能不能看明白，这样确实很难叙述的明白。但是如果实际做起来就会明白。

楼主的程序是滚动的吗？我学习下

就是显示，清除，移动位置，显示，清除，移动位置，显示的过程
