STM8控制LCD12864液晶屏实验
2024-05-12 23:22:02
本文分以下几个部分：
第一部分：并口传输显示中英文
第二部分：并口传输显示图片
第三部分：串口传输
首先说明，我使用的LCD12864是采用ST7920控制器芯片的，操作LCD12864其实是在操作ST7920
第一部分 并口传输显示中英文
主要是以下几个函数:
首先：写一个LCD_write函数来给LCD发送数据.根据时序图，发送数据是RW要置0，E要产生下降沿，RS置1为数据，RS置0为命令，由于是并口传输PSB置1.
其次：能够给LCD发命令后，我们就要使用LCD_init函数发送初始化命令。初始化命令至少包括：1、设置显示，2、功能设定，3、初始化清屏3个部分。
写命令时注意每个命令都有自己的运行时间，记得保证足够延时。
第三：写一个LCD_display函数可以分行分列显示内容。
void LCD_write(u8 data,u8 cmd_flag);
void LCD_init(void);
void LCD_display(u8 row,u8 col,u8 *string);一、并口方式理论及资料
1.先上时序图：
这里要注意的是 PWeh 要大于450ns 以STM8S208MB内部16M RC振荡器计算，每次执行时间为： 1s/(16M/8分频) =500ns 所以必须延时保证E引脚上升区域大于450ns。
同理 tdsw也需要延时。
2.指令表
ST7920指令集分为2种，第一种：10种基础指令集RE=0，第二种：6种高级指令集RE=0
第一部分是显示中英文，所以只需用到基础指令集RE=0
3.引脚图和硬件电路
4.为什么每行可以写八个汉字或16个英文/数字？
因为每个汉字需要占2个字节。
此外还要留意，第一行和第三行的内存地址是连在一起的，不控制光标的话，写完第一行就会换行到第三行。（光标写完是自动加一的）

}5.实验效果
第二部分 并行显示图片
1、指令集
使用绘图功能需要打开扩展指令集
2、绘画步骤
1.使用扩展指令集并关闭绘图显示功能 0X34
2.设置垂直地址
3.设置水平地址
4.写D15~D8位
5.写D7~D0位
6.打开绘图显示功能 0X36
7.返回基本指令集
垂直地址：表示方法 第几行+偏移量 例如： 0x80+j
水平地址：第一行0X80 第二行0X90 第三行0X88 第四行0X98
这部分处理函数如下：
void LCD_pic(u8 *pic)
{u8 i,j,k;LCD_write(0X34,0);delay(10);for ( i = 0; i <2; i++){for ( j = 0; j <32; j++){LCD_write(0X80+j,0);LCD_write(0X80+8*i,0);for ( k = 0; k <16; k++){LCD_write(*pic++,1);}}}LCD_write(0X36,0);delay(10);LCD_write(0X30,0);delay(10);
}3、再来看GDRAM
其实12864 只用了GDRAM的一半
Y坐标取值范围：0X80+0-31
X坐标取值范围：0X80或者0X88

}实验效果：
这里说一下怎么得到DIS数组的
用PS制作一张128*64的BMP图片
然后将其导入 字模提取 软件中 用C51格式取模即可
第三部分 串口传输
串口传输非常省GPIO，可以做到用两个GPIO控制整块显示屏。非常给力！
选择串口通讯模式需要把PSB置0（或接GND）
此时 RS变为了片选端口 我们直接置1（或接VDD）
RW变成了SDIO 我们用它来发送数据 （接GPIO）
把EN变成了SCLK 我们用它来给通讯时钟（接GPIO）
1. 串口输出时序图
比如 我们发送一个命令 0X34到LCD，可以
11111 0 0 0 （命令控制字）0XF8
0011 0000 ( 0X34的高4位) 0X30
0100 0000( 0X34的低4位) 0X40
通过仔细观察时序图，我们发现：时钟为0时可以改变数据，时钟为1时采集。所以大体思路是在CLK=0时装载，在CLK=1时发射。
2. 需要写的函数
通过上面的分析总结出我们需要以下函数：
① 一个将命令/数据分解成3个字节并发送的处理函数
void LCD_write(u8 data,u8 cmd_flag)
{if(cmd_flag)LCD_send_byte(0XFA);elseLCD_send_byte(0XF8);LCD_send_byte(data & 0XF0);LCD_send_byte((data<<4) & 0XF0);
}②一个控制时钟引脚并将数据在SDIO口逐位发送的函数
LCD_send_byte(u8 byte)
{for (u8 i = 0; i < 8; i++){LCDCLK=0;if ((byte<<i) & 0X80)LCDDIO=1;elseLCDDIO=0;LCDCLK=1;}
} 3.程序（用并行显示图片程序改的）
