lcd12864程序流程图

lcd12864 程序流程图
我们常用的人机交互显示界面中，除了数码管，LED，以及我们之前已经提到的LCD1602 之外，还有一种液晶屏用的比较多。

相信接触过单片机的朋友都知道了，那就是12864 液晶。

顾名思义，12864 表示其横向可以显示128 个点，纵向可以显示64 个点。

我们常用的12864 液晶模块中有带字库的，也有不带字库的，其控制芯片也有很多种，如KS0108 、T6963，ST7920 等等。

在这里我们以ST7920 为主控芯片的12864 液晶屏来学习如何去驱动它。

（液晶屏采用金鹏的OCMJ4X8C）。

lcd12864 液晶说明：
我们先来了解一下它的并行连接情况。

下面是电路连接图：
上面的图可以看出，液晶模块和单片机的连接除了P0 口的8 位并行数据线之外，还有RS，RW，E 等几根线。

其中R/S 是指令和数据寄存器的选择控制线（串行模式下为片选），R/W 是读写控制线（串行模式下是数据线），E 是使能线（串行模式下为时钟线）。

通过这几根控制线和数据线，再结合它的时序图，我们就可以编写出相应的驱动程序啦。

看看并行模式下的写时序图：。

4. 设置Y地址设置Y地址计数器的值。 0x40: 第一列。
5. 读状态 BUSY: 即BF，如前所述。 ON/OFF: 显示的开关状态。 RST: 表示内部正在初始化,此时组件不接受任何指令和数据。
6. 写显示数据按照表1的位置，存储显示数据。数据为1，表示该点显示；数据为0，该点不显示。取模方式：纵向字节倒序。

DR是用于寄存数据的，与指令寄存器寄存指令相对应。当D/I=1时，在下降沿作用下，图形显示数据写入DR，或在E信号高电平作用下由DR读到DB7～DB0数据总线。DR和DDRAM之间的数据传输是模块内部自动执行的。

1.3 外形尺寸
1.4 硬件构成说明
IC2控制模块的左半屏，IC1控制模块的右半屏。IC3为行驱动器，IC1和IC2 为列驱动器。IC1、IC2、IC3 含有以下主要功能器件。 1. 指令寄存器(IR)
IR是用于寄存指令码，与数据寄存器数据相对应。当D/I=0时，在E信号下降沿的作用下，指令码写入IR。 2. 数据寄存器(DR)
表1 DDRAM地址
6. 显示数据RAM DDRAM DDRAM是存储图形显示数据的。数据为1，表示该点显示；数据为0，该点不
显示。DDRAM与地址和显示位置的关系见DDRAM地址表。 7. Z地址计数器
Z地址计数器是一个6位计数器。此计数器具备循环记数功能。它是用于显示行扫描同步，当一行扫描完成，此地址计数器自动加1，指向下一行扫描数据。 RST复位后Z地址计数器为0。

XY地址计数器是一个9位计数器，高3位是X地址计数器，低6位为Y地址计数器。XY地址计数器实际上是作为DDRAM的地址指针。X地址计数器为DDRAM的页指针，Y地址计数器为DDRAM的Y地址指针。
X地址计数器是没有记数功能的，只能用指令设置。 Y地址计数器具有循环记数功能，各显示数据写入后，Y地址自动加1。Y地址指针从0到63。
