一、SPI介绍

Ⅰ.什么是SPI

  SPI总线是一种4线总线，因其硬件功能很强，所以与SPI有关的软件就相当简单，使中央处理器（Central Processing Unit，CPU）有更多的时间处理其他事务。

  SPI是一种高速、高效率的串行接口技术。通常由一个主模块和一个或多个从模块组成：主模块选择一个从模块进行同步通信，从而完成数据的交换。

  SPI是一个环形结构，通信时需要至少4根线（事实上在单向传输时3根线也可以）

Ⅱ.SPI接口介绍

  4线SPI器件有四个信号：

  🎈时钟(SPI CLK, SCLK)

  🎈片选(CS)

  🎈主机输出、从机输入(MOSI)

  🎈主机输入、从机输出(MISO)

  接口图·如下所示：
在这里插入图片描述

  产生时钟信号的器件称为主机。主机和从机之间传输的数据与主机产生的时钟同步。同I2C接口相比，SPI器件支持更高的时钟频率。

  SPI接口只能有一个主机，但可以有一个或多个从机。上图显示了主机和从机之间的SPI连接。

  来自主机的片选信号用于选择从机。这通常是一个低电平有效信号，拉高时从机与SPI总线断开连接。当使用多本文中的片选信号始终是低电平有效信号。

  MOSI和MISO是数据线。MOSI将数据从主机发送到从机，MISO将数据从从机发送到主机。

Ⅲ.数据传输

  开始SPI通信:主机必须发送时钟信号，并通过使能CS信号选择从机。

  片选通常是低电平有效信号。因此，主机必须在该信号上发送逻辑0以选择从机。SPI是全双工接口，主机和从机可以分别通过MOSI和MISO线路同时发送数据。在SPI通信期间，数据的发送（串行移出到MOSI/SDO总线上）和接收（采样或读入总线(MISO/SDI)上的数据）同时进行。串行时钟沿同步数据的移位和采样。SPI接口允许用户灵活选择时钟的上升沿或下降沿来采样和/或移位数据。

Ⅳ.工作模式

  (1)CPHA=0，表示第一个边沿采样

  ]🎈对于CPOL=1，idle时为高电平，第一个边沿就是从高变到低，是下降沿，所以是下降沿采样。
  🎈对于CPOL=1，idle时为高电平，第一个边沿就是从高变到低，是下降沿，所以是下降沿采样。

  (2)CPHA=1，表示第二个边沿采样

  🎈对于CPOL=0，idle时为低电平，第二个边沿就是从高变到低，是下降沿，所以是下降沿采样。

  🎈对于CPOL=1，idle时为高电平，第二个边沿就是从低变到高，是上升沿，所以是上升沿采样。

Ⅴ.优缺点

项目Value
优点缺点
支持全双工，push-pull的驱动性能相比open-drain信号完整性更好；相比IIC多两根线
支持高速（100MHz以上）没有寻址机制，只能靠片选选择不同设备
协议支持字长不限于8bits，可根据应用特点灵活选择消息字长没有从设备接受ACK，主设备对于发送成功与否不得而知
硬件连接简单典型应用只支持单主控

二、OLED屏显字模提取

Ⅰ.OLED定义

  OLED，即有机发光二极管（Organic Light-Emitting Diode），又称为有机电激光显示（Organic Electroluminesence Display，OELD)。OLED显示技术具有自发光的特性，采用非常薄的有机材料涂层和玻璃基板，当有电流通过时，这些有机材料就会发光，而且OLED显示屏幕可视角度大，并且能够节省电能。

Ⅱ.OLED模块介绍

  在本次实践中，采用的是0.94寸的OLED，详细参数如下：

  (1)模块尺寸：27.3（L） * 27.8（W） mm

  (2)电源电压： 2.8-5.5V DC

  (3)驱动芯片： SSD1306

  (4)引脚定义： VCC-电源正极 GND-电源负极 D0-时钟线 D1-数据线 RES-复位线 DC-数据/命令 CS-片选

  (5)重量： 4g

  (6)通信方式： 默认为 4 线 SPI， 可更改为 3 线 SPI 和 IIC 通信

三、字模提取

Ⅰ.字模定义

  单片机应用经常会用到液晶显示模块，是用点阵的方式显示的，要显示汉字或字符的时候会用到字模，字模就是字在点阵上显示时对应的编码，如图1显示的“正”字，使用16×16点阵。点阵中白色的点是高亮的，对应于二进制编码中的1，黑色的低亮对应于二进制编码中的0。如第一行二进制编码应该是 00000000 00001000 刚好用两个字节表示就是 0x0,0x08，这样，16总共需要用32个字节来表示，这32个字节就是“正”的字模。在单片机程序中，将字模发送给液晶显示模块，就能够显示出响应的汉字或字符。

Ⅱ.取字模原理

  汉字的点阵字模是从点阵字库文件中提取出来的。例如常用的16×16点阵HZK16文件，12×12点阵HZK12文件等等，这些文件包括了GB2312字符集中的所有汉字。现在只要弄清汉字点阵在字库文件中的格式，就可以按照自己的意愿去显示汉字了。

  以HZK16文件为例，分析取得汉字点阵字模的方法。HZK16文件是按照GB 2312-80标准，也就是通常所说的国标码或区位码的标准排列的。国标码分为 94 个区（Section），每个区 94 个位（Position），所以也称为区位码。其中01～09 区为符号、数字区，16～87 区为汉字区。而 10～15 区、88～94 区是空白区域。

Ⅲ.取得汉字的区位的方法

  在计算机处理汉字和ASCII字符时，使每个ASCII字符占用1个字节，而一个汉字占用两个字节，其值称为汉字的内码。其中第一个字节的值为区号加上32（20H），第二个字节的值为位号加上32（20H）。为了与ASCII字符区别开，表示汉字的两个字节的最高位都是1，也就是两个字节的值都又加上了128（80H）。这样，通过汉字的内码，就可以计算出汉字的区位码。

  具体算式如下:

qh=c1-32-128=c1-160 wh=c2-32-128=c2-160

  其中，qh，wh 为汉字的区号和位号，cl，c2 为汉字的第一字节和第二字节。根据区号和位号可以得到汉字字模在文件中的位置∶location=（94*（qh-1）+（wh-1））*一个点阵字模的字节数。

}

五、滚动显示长字符

Ⅰ.程序准备

  在第四部分基础上，进行代码修改——添加使屏滚动的代码即可！
  方法①：直接控制硬件刷新效果

   原理：左右滚动滑动的实现，是使用单独的1KB内存，去处理图片拼接后的图像。而由于刷屏方式比较特殊，左右拼接的方式就是内存移位，而且是Byte与Byte间的移位，这就更方便了。

  一般有如下滚动方式：

0x2F:激活滚动        				0x2E:关闭滚动
0x26:水平滚动右向	   				0x27:水平滚动左向
0x29:水平和垂直滚动右向				0x2A:水平和垂直滚动左向
0xA3:垂直滚动

  硬件实现方法：

//硬件滚动
void roll(void)
{  OLED_WR_Byte(0x2F, OLED_CMD);  OLED_WR_Byte(0x27, OLED_CMD);   OLED_WR_Byte(0x00,OLED_CMD);       OLED_WR_Byte(0x00,OLED_CMD);        OLED_WR_Byte(0x07,OLED_CMD);        OLED_WR_Byte(0x2E,OLED_CMD); 	while(1);
}

  ‘  方法②：软件实现滚动

  编程实现改变坐标来实现滚动，通过操作GUI_ShowFont16(u8 x,u8 y,u8 *s,u8 mode)来实现了。但是相对来说就没那么流畅了。

  实现代码如下：

void Roll_display(void)
{int i,j;for(j=0;j<=1;j++)for(i=120;i>=-176;i-=8){if(i<120&&i>0)GUI_ShowFont16(i,22,"信",1);if(i+16<120&&i+16>0)GUI_ShowFont16(i+16,22,"息",1);if(i+32<120&&i+32>0)GUI_ShowFont16(i+32,22,"科",1);if(i+48<120&&i+48>0)	GUI_ShowFont16(i+48,22,"学",1);if(i+64<120&&i+64>0)GUI_ShowFont16(i+64,22,"与",1);if(i+80<120&&i+80>0)GUI_ShowFont16(i+80,22,"工",1);if(i+96<120&&i+96>0)GUI_ShowFont16(i+96,22,"程",1);if(i+112<120&&i+112>0)	GUI_ShowFont16(i+112,22,"学",1);if(i+128<120&&i+128>0)GUI_ShowFont16(i+128,22,"院",1);if(i+144<120&&i+144>0)GUI_ShowFont16(i+144,22,"通",1);if(i+160<120&&i+160>0)GUI_ShowFont16(i+160,22,"信",1);if(i+176<120&&i+176>0)GUI_ShowFont16(i+176,22,"工",1);if(i+192<120&&i+192>0)GUI_ShowFont16(i+192,22,"程",1);delay_ms(200);OLED_Clear(0); //清屏}
}

};

2.添加屏显代码

  在text.c中添加如下代码：

void TEST_MainPage(void)
{	GUI_ShowCHinese(46,16,32,"白茶清欢无别事，我在等风也等你，苦酒折柳今相离，无风无月也无你。",1);delay_ms(1500);		delay_ms(1500);
}

3.添加滚动代码

  在mainc中添加如下代码：

int main(void)
{	delay_init();	    	       //延时函数初始化	  OLED_Init();			         //初始化OLED  OLED_Clear(0);             //清屏（全黑）OLED_WR_Byte(0x2E,OLED_CMD);        //关闭滚动OLED_WR_Byte(0x00,OLED_CMD);        //虚拟字节OLED_WR_Byte(0x00,OLED_CMD);        //起始页 0OLED_WR_Byte(0x07,OLED_CMD);        //滚动时间间隔OLED_WR_Byte(0x07,OLED_CMD);        //终止页 7OLED_WR_Byte(0x00,OLED_CMD);        //虚拟字节OLED_WR_Byte(0xFF,OLED_CMD);        //虚拟字节TEST_MainPage();OLED_WR_Byte(0x2F,OLED_CMD);        //开启滚动while(1) {	}
}

  
  
  
  

Ⅳ.烧录运行

六、显示AHT20的温度和湿度

Ⅰ.程序准备

  只要实现了OLED屏显，之后的任务就会简单很多。在上一篇的博客https://blog.csdn.net/houlile_sunny/article/details/127638504中，已经实现温湿度数据的采集，后续只需要将OLED的代码移植到“温湿度数据采集”那里即可

  在温湿度采集数据的那篇博客基础上，只需要将OLED屏显文件中的头文件和.c文件添加到文件中即可。
在这里插入图片描述

Ⅱ.文字取模

  文字取模和上述方法一样，在此不做重复说明。

Ⅲ.修改代码

1.添加字模字段

  在oledfont.h文件中加入提示显示温湿度的文字，代码如下：

typedef struct 
{unsigned char Index[2];	char Msk[32];
}typFNT_GB16; //宋体
//16*16大小
//逐行式，顺向（高位在前）
const typFNT_GB16 cfont16[] = 
{"温",0x00,0x00,0x23,0xF8,0x12,0x08,0x12,0x08,0x83,0xF8,0x42,0x08,0x42,0x08,0x13,0xF8,
0x10,0x00,0x27,0xFC,0xE4,0xA4,0x24,0xA4,0x24,0xA4,0x24,0xA4,0x2F,0xFE,0x00,0x00,/*"温",0*/
"度",0x01,0x00,0x00,0x80,0x3F,0xFE,0x22,0x20,0x22,0x20,0x3F,0xFC,0x22,0x20,0x22,0x20,
0x23,0xE0,0x20,0x00,0x2F,0xF0,0x24,0x10,0x42,0x20,0x41,0xC0,0x86,0x30,0x38,0x0E,/*"度",1*/};const typFNT_GB16 a_cfont16[] = 
{"湿",0x00,0x00,0x27,0xF8,0x14,0x08,0x14,0x08,0x87,0xF8,0x44,0x08,0x44,0x08,0x17,0xF8,0x11,0x20,0x21,0x20,0xE9,0x24,0x25,0x28,0x23,0x30,0x21,0x20,0x2F,0xFE,0x00,0x00,/*"湿",0*/"度",0x01,0x00,0x00,0x80,0x3F,0xFE,0x22,0x20,0x22,0x20,0x3F,0xFC,0x22,0x20,0x22,0x20,0x23,0xE0,0x20,0x00,0x2F,0xF0,0x24,0x10,0x42,0x20,0x41,0xC0,0x86,0x30,0x38,0x0E,{0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00},
{0x00,0x00,0x30,0x00,0x30,0x00,0x00,0x00,0x30,0x00,0x30,0x00,0x00,0x00,0x00,0x00},/*"：",0*/};

2.添加显示代码

  在text.c文件中，添加输出温湿度屏显的代码，代码如下：

void TEST_MainPage(u32 Tem,u32 Hum)
{	GUI_ShowCHinese(10,0,16,"温度",1);GUI_ShowString(40,0,":",16,1);GUI_ShowCHinese1(10,20,16,"湿度",1);GUI_ShowString(40,20,":",16,1);	GUI_ShowNum(50,0,(u32 *)(Tem/10),2,16,1);GUI_ShowString(68,0,".",16,1);GUI_ShowNum(75,0,(u32 *)(Tem%10),1,16,1);GUI_ShowNum(50,20,(u32 *)(Hum/10),2,16,1);GUI_ShowString(68,20,".",16,1);GUI_ShowNum(75,20,(u32 *)(Hum%10),1,16,1);GUI_ShowString(85,0,"*c",16,1);GUI_ShowString(85,20,"%",16,1);delay_ms(1500);	delay_ms(1500);
}
``### 3.修改主函数
<font name="宋体" size=3>&emsp;&emsp;(1)添加初始化OLED代码</font>```cdelay_init();	    	      NVIC_Configuration(); 	   OLED_Init();			         OLED_Clear(0);

  (2)在while循环中添加如下代码，实现温湿度采集

Temp = AHT20.te * 10;Hum = AHT20.rh * 10;TEST_MainPage(Temp,Hum);//GUI_ShowNum(52,0,52,2,16,1);printf("温度:%.2f°c  湿度:%.2f%%\n",AHT20.te,AHT20.rh);//Delay_ms(1000);

Ⅳ.烧录运行

1.编译

  代码完成后，首先进行编译，编译通过后进行烧录

在这里插入图片描述

2.烧录代码，观察现象

  利用Flymcu将代码烧录到单片机中，连接好硬件电路后观察现象。输出结果如下动图所示

在这里插入图片描述

六、总结

严格按照官方提供的模式进行，字模修改，之前由于偷懒，字模只写成这种模式：

{
0x08,0x80,0x08,0x80,0x08,0x80,0x11,0xFE,0x11,0x02,0x32,0x04,0x34,0x20,0x50,0x20},{0x91,0x28,0x11,0x24,0x12,0x24,0x12,0x22,0x14,0x22,0x10,0x20,0x10,0xA0,0x10,0x40},/*"你",30*/

导致汉字显示一直有问题，一定要严格按照如下模式进行：


"你",0x08,0x80,0x08,0x80,0x08,0x80,0x11,0xFE,0x11,0x02,0x32,0x04,0x34,0x20,0x50,0x20},0x91,0x28,0x11,0x24,0x12,0x24,0x12,0x22,0x14,0x22,0x10,0x20,0x10,0xA0,0x10,0x40},/*"你",30*/
