买12864液晶屏时，厂家都会给测试程序的，就是C语言的。根据测试程序，改一下引脚定义就行了，编译一下测试程序，看能不能显示。如果能显示了，就可以自己根据测试程序一点点修改。

如果找不到厂家，就只好在网上找了，但不容易与你的晶屏相符。

实在不会，读一下测试程序，显示汉字的方法都是，用汉字取模软件，先取汉字点阵数据，用这些数据代替测试程序的点阵数据，看是不是能显示自己的取模的汉字了。

因液晶屏显示汉字，取模方式有多种，如果显示乱码，说明取模方式不对，再换一种，直到显示出汉字为止。这样就可以，对测试程序进行修改成自己看得懂，又实用的程序了。

以上就是关于求一FPGA控制LCD12864程序，程序用VHDL编写，且LCD是串行发送数据，急求！！！全部的内容，包括:求一FPGA控制LCD12864程序，程序用VHDL编写，且LCD是串行发送数据，急求！！！、用AT89C52，使其在128*64点阵LCD屏幕上显示“河南理工大学”，并向上滚动显示，一下是部分程序，帮忙解释、求一个STC-89C52RC控制12864液晶显示的程序等相关内容解答，如果想了解更多相关内容，可以关注我们，你们的支持是我们更新的动力！
