基于I2C协议的OLED显示(利用U82G库)

一、实验目的：

1、了解I2C协议的基本原理和时序协议；

2、掌握0.96寸OLED屏的工作原理，汉字点阵显示原理；

3、掌握开源GUI库U82G在stm32上的移植编译方法，以及图形界面可视化技术。

一、I2C协议的基本原理和时序协议

I2C通信协议的原理

I2C通信协是由一根时钟线、一根数据线组成，是同步的（有时钟线控制时间，若遇到中断去执行别的程序，通信不会被打算），由一根数据线完成接收和发送数据，是半双工模式，为了实时的知道数据的接收信息设置了数据应答，支持连接多个外设。本文主要使用一主多从模式。
一主多从：一个主机，多个从机，从机默认无法操作数据线，主机可选择某个从机使其短暂的可以操作数据线。
多主多从：也是一个主机，多个从机，但从机可以与主机互换身份。

I2C时序基本单元

•起始条件：SCL高电平期间，SDA从高电平切换到低电平

•终止条件：SCL高电平期间，SDA从低电平切换到高电平

发送一个字节：

SCL低电平期间，主机将数据位依次放到SDA线上（高位先行），然后释放SCL，从机将在SCL高电平期间读取数据位，所以SCL高电平期间SDA不允许有数据变化，依次循环上述过程8次，即可发送一个字节

接收一个字节：

SCL低电平期间，从机将数据位依次放到SDA线上（高位先行），然后释放SCL，主机将在SCL高电平期间读取数据位，所以SCL高电平期间SDA不允许有数据变化，依次循环上述过程8次，即可接收一个字节（主机在接收之前，需要释放SDA）

•发送应答：主机在接收完一个字节之后，在下一个时钟发送一位数据，数据0表示应答，数据1表示非应答

•接收应答：主机在发送完一个字节之后，在下一个时钟接收一位数据，判断从机是否应答，数据0表示应答，数据1表示非应答（主机在接收之前，需要释放SDA）

I2C时序

•指定地址写

•对于指定设备（Slave Address），在指定地址（Reg Address）下，写入指定数据（Data）

•当前地址读

•对于指定设备（Slave Address），在当前地址指针指示的地址下，读取从机数据（Data）

•指定地址读

•对于指定设备（Slave Address），在指定地址（Reg Address）下，读取从机数据（Data）

二、建立工程

RCC配置

外部高速晶振（精度更高）——HSE；

SYS配置Debug设置成Serial Wire（否则可能导致芯片自锁)；

I2C2配置作为OLED的通讯方式

TIM1配置

U8g2图形库需要us级延迟推动（U8g2的心跳）

时钟树配置

工程配置

三、U8g2移植

精简u8g2_d_setup.c

​ 由于笔者的OLED是IIC接口，只留一个本次要用到u8g2_Setup_ssd1306_i2c_128x64_noname_f就好（如果是SPI接口，需要使用u8g2_Setup_ssd1306_128x64_noname_f这个函数），其它的可以删掉或注释掉。

精简u8g2_d_memory.c

​ 由于用到的u8g2_Setup_ssd1306_i2c_128x64_noname_f函数中，只调用了u8g2_m_16_8_f这个函数，所以留下这个函数，其它的函数一定要删掉或注释掉，否则编译时很可能会提示内存不足

2.显示网名昵称

中文取模步骤

1.打开PCtoLCD2002

2.选择模式 - 字符模式

3.点击选项，进行设置，

4.在输入栏输入需要取模的汉字（只能是汉字），然后点击生成字模。

以下是我用取模工具提取的位图数据：

3.滑动显示

思路：因为oled屏幕是128*64规格的，所以x坐标在（0，128）之间，为了实现滑动（以右滑动为例子）中定义横坐标x为变量，通过改变x的值从而实现滑动，向其它方位滑动同理（上下滑动设置变量y）

以右滑动为例子，其余同理

unsigned int x=16;
  while (1)
  {
		if(x<=128)
		{
			x++;//向右滑动，可以提高每次x的增加量来控制滑动速度
		}
		else if(x>128)//置零
		{
			x=0;
		}
				u8g2_SetFont(&u8g2,u8g2_font_ncenB12_tf);//设置字体格式
				u8g2_DrawXBMP(&u8g2,x,0,16,16,luo);
				u8g2_DrawXBMP(&u8g2,x+16,0,16,16,bi);
				u8g2_DrawXBMP(&u8g2,x+32,0,16,16,tai);
				u8g2_DrawXBMP(&u8g2,x+48,0,16,16,huang);
				u8g2_DrawXBMP(&u8g2,x+64,0,16,16,zhang);

U8g2库操作位图的方法主要有

void u8g2_DrawBitmap(u8g2_t *u8g2, u8g2_uint_t x, u8g2_uint_t y, u8g2_uint_t cnt, u8g2_uint_t h, const uint8_t *bitmap);
void u8g2_DrawXBM(u8g2_t *u8g2, u8g2_uint_t x, u8g2_uint_t y, u8g2_uint_t w, u8g2_uint_t h, const uint8_t *bitmap);
void u8g2_DrawXBMP(u8g2_t *u8g2, u8g2_uint_t x, u8g2_uint_t y, u8g2_uint_t w, u8g2_uint_t h, const uint8_t *bitmap);

几种方法的实现都大同小异，所以选取了如下的方法进行绘制操作

u8g2_DrawXBMP(&u8g2, 0, 0, wall_e_bmp01_x,wall_e_bmp01_y, wall_e_bmp01);
u8g2_SendBuffer(&u8g2);

效果如下：

总结

利用u8g2能让oled显示图案，汉字，字符等，让我感受到了单片机学习的乐趣
