SPI方式来驱动12864液晶

SPI方式来驱动12864液晶

SPI⽅式来驱动12864液晶这是⽤SPI⽅式来驱动12864液晶的源程序，液晶屏的控制芯⽚为ST7565P经测试SPI的时钟可达到振荡频率的⼆分频。

⽐⽤普通IO⼝模拟串⾏的⽅式快多了。

下⾯贴出源代码，有详细注释。

本程序简单实⽤，可拿去作简单参考。

12864液晶经典驱动程序,一看就懂,有详细的注释(C语言编写,不看后悔)

这个程序写得很好，自己也是看的别人写的很好的程序，但是它代码不够完整，注释不详细，经过自己的修改加以完善。

另外我发现很多的测试代码都没有附上测试代码效果图，在本人的代码下面有自己拍的效果图，填补不足之处。

AMPIRE12864驱动程序

AMPIRE12864驱动程序

AMPIRE12864驱动程序一、芯片介绍AMPIRE12864图形点阵液晶显示器，它主要采用动态驱动原理由行驱动&mdash;控制器和列驱动器两部分组成了128(列)&times;64(行)的全点阵液晶显示。

可显示8&times;4个16&times;16点阵汉字或16&times;4个16&times;8点阵ASCII字符集，也可完成图形的显示。

与CPU接口采用5条位控制总线和8位并行数据总线输入输出，具有4位/8位并行、2线或3线串行多种接口方式。

AMPIRE12864共18个引脚其中包括8个三态数据引脚，5个控制信号引脚，1个复位引脚和4个电源相关引脚。

AMPIRE12864详细引脚描述见表2-7。

此RAM的每一位数据对应显示面板上一个点的显示（数据为H）与不显示（数据为L）。

DDRAM的地址与显示位置关系对照如表2-8所示。
