[嵌入式]STM32 OLED屏（I2C接口）显示

SSD1306

OLED特性

型号：SSD1306
SSD1306是一款单芯片CMOS OLED/PLED驱动器，带有用于有机/聚合物发光二极管点阵式图形显示系统的控制器。它由128个段和64个公共区组成。该集成电路是为普通阴极型OLED面板设计的。

SSD1306内置对比度控制、显示RAM和振荡器，减少了外部元件的数量和功耗。它有256步亮度控制。数据/命令通过硬件可选的6800/8000系列兼容并行接口、I2C接口或串行外围接口从通用MCU发送。

它适用于许多小型便携式应用，如手机子显示器、MP3播放器和计算器等。

手册说明

GDDRAM是存放显示数据的，其大小为128x64bits.RAM划分为8个页，从PAGE0~PAGE7.
每页内1个SEG对于一个Byte数据，一页有128Byte组成。一帧显示数据为1024Byte

在这里插入图片描述

从下图中可以看到SEG与COM的关系
整个画面有8个页面，每个页面有8个COM，128个SEG

涉及到一些配置寄存器，这就要查看手册，手册中有好几组寄存器

一、基本命令

命令	含义	使用说明
81	设置对比度	0x00~0xff 双字节命令，1-256对比等级，值增大，对比度增加
A4/A5	全显示开关	A4 x0=0b 重新显示RAM内容；A5 X0=1b 全部显示开
A6/A7	设置正常/翻转显示	A6,X[0]=0b,正常显示；A7,X[0]=1b:翻转显示
AE/AF	设置显示开/关	AE,X[0]=0b，关(睡眠模式)；AF,X[0]=01b ON

二、地址设置命令

命令	含义	使用说明
00-0F	页地址模式下，设置低列起始地址	起始行寄存器显示在重置后设置0000b
10-1F	页地址模式下，设置高列起始地址	起始行寄存器显示在重置后设置0000b
20	设置寄存器地址模式	A[1:0]=00b水平地址模式，01b 垂直地址模式，10页地址模式，11b无效
21	设置列地址	设置列起始结束地址，A[6:0],start ;B[6:0] end
22	设置页地址	A[2:0]:起始地址范围0_{7d，B[2:0]页结束地址范围0}7d（复位：7d）
B0~B7	在页地址模式下，设置页起始地址	(PAGE0~PAGE7) for Page Addressing Modeusing X[2:0]

三、硬件配置命令

命令	含义	使用说明
40~7F	设置显示起始行
A0/A1	设置SEG重映射	A0h,X[0]=0b:列地址0，映射到SEG0(复位)；A1h,x[0]=1b:列地址127映射到SEG0
A8	设置多路复用
C0/C8	设置COM输出扫描模式	C0h，X[3]=0b:z=正常模式扫描 COM0_{COM[N-1];C8xX[3]=1b：重映射模式，扫描COM[N-1]}COM[0]
D3	设置显示偏移	设置垂直偏移
DA	设置COM引脚硬件配置

四、滚动命令

命令	含义	使用说明
26/27	垂直水平滚动	26h x[0]=0 ,水平向右滚动；27 x[0]=1 水平向左滚动
29/2A	垂直滚动	29,向右+（上下）；2A向左+（上下）

在测试时，26,27命令没有效果，29,2A可以实现左右，左右+上下滚动的效果
开启命令码后，设置以下A,B,C,D,E参数，参数如下：在这里插入图片描述
滚动实例，在初始化时调用,26/27没有实验成功，29/2A可以实现滚动

void roll()
{
    WriteCmd(0x2e);//OFF
    WriteCmd(0x2A);//29,2a
    WriteCmd(0x00);//A:Dummy byte
    WriteCmd(0x00);//B:设置页起始地址
    WriteCmd(0x02);//C:滚动速度 000b-5frames 100b-3frames
	WriteCmd(0x01);//D:设置页结束地址
    WriteCmd(0x00);//E:垂直滚动偏移
	WriteCmd(0x2f);//START ROLL
}

GDDRAM寻址模式（0x20）

有三种模式设置，例如：

	OLED_WriteC(0X20);	// 设置模式
	OLED_WriteC(0X00);	// 设置值（水平寻址模式 ）

页寻址、A[1:0]=10
在这里插入图片描述
水平寻址、A[1:0]=00

垂直寻址 A[1:0]=01

I2C地址与时序

在这里插入图片描述
这段话的意思是，SA0 提供可扩展的从机地址，通过SA0(D/C#)脚的上拉和下拉来设置从机地址，拉高则为1，即 0111101；拉低则为0，即0111100
最后一个是读写R/W

I2C地址为0x78

I2C收发数据开始和结束时序
在这里插入图片描述
IIC写入时序如下所示：

主机先发起开始（START）信号(SDA从高到底，SCL从底到高)，
然后发送1byte首字节，包括从机地址(7位)和读写数据位(1位，最低位，0为写模式)，
驱动器识别从机地址为本机地址之后，将会发出应答信号(ACK)
主机收到从机的应答信号之后，随后传输命令或者数据。一个控制字节主要由CO 和 D/C# 位后面再加上六个0组成的。
接受每一个控制字节或者数据字节都要产生ACK信号
传输完毕之后主机发出结束（STOP）信号,SDA 从低到高 SCL保持高
