OLEDSSD1306与SSD1315在初始化的区别在使⽤0.96⼨的OLED时，发现之前的代码不能正常通过单⽚机的IIC使⽤DMA进⾏刷新，刷新时总是错⼀位，后来查阅资料发现是现在的OLED使⽤了SSD1315替换了SSD1306控制芯⽚，贴⼀下各个初始化过程，⽅便记录：SSD1306初始化：1/**2 * @brief OLED初始化3 * @param None4 * @retval None.5*/6void OLED_Init(void)7 {8#if SENDDTA_DMA9 I2C_DMA_WriteReg( (uint8_t*)OLED_Init_CMD, OLED_ADDRESS,OLED_WriteCom_Addr,sizeof(OLED_Init_CMD)); //sizeof(OLED_Init_CMD)10#else11// DelayMs(100); //这⾥的延时很重要12 delay_ms(10);13 WriteCmd(0xAE); //display off14 WriteCmd(0x20); //Set Memory Addressing Mode15 WriteCmd(0x10); //00,Horizontal Addressing Mode;01,Vertical Addressing Mode;10,Page Addressing Mode (RESET);11,Invalid16 WriteCmd(0xb0); //Set Page Start Address for Page Addressing Mode,0-717 WriteCmd(0xc8); //Set COM Output Scan Direction18 WriteCmd(0x00); //---set low column address19 WriteCmd(0x10); //---set high column address20 WriteCmd(0x40); //--set start line address21 WriteCmd(0x81); //--set contrast control register22 WriteCmd(0xff); //亮度调节 0x00~0xff23 WriteCmd(0xa1); //--set segment re-map 0 to 12724 WriteCmd(0xa6); //--set normal display25 WriteCmd(0xa8); //--set multiplex ratio(1 to 64)26 WriteCmd(0x3F); //27 WriteCmd(0xa4); //0xa4,Output follows RAM content;0xa5,Output ignores RAM content28 WriteCmd(0xd3); //-set display offset29 WriteCmd(0x00); //-not offset30 WriteCmd(0xd5); //--set display clock divide ratio/oscillator frequency31 WriteCmd(0xf0); //--set divide ratio32 WriteCmd(0xd9); //--set pre-charge period33 WriteCmd(0x22); //34 WriteCmd(0xda); //--set com pins hardware configuration35 WriteCmd(0x12);36 WriteCmd(0xdb); //--set vcomh37 WriteCmd(0x20); //0x20,0.77xVcc38 WriteCmd(0x8d); //--set DC-DC enable39 WriteCmd(0x14); //40 WriteCmd(0xaf); //--turn on oled panel41#endif42 }这⾥使⽤默认是刷新⽅式，按照页写数据没有问题，使⽤DMA时需要把照寻址⽅式修改为了⽔平寻址时就出现了刷新数据不对的问题为此，我直接使⽤了⽹络上默认的⽅式对DMA发送指令进⾏初始化const uint8_t OLED_Init_CMD[] ={0xAE,0x00,0x10,0x40,0xB0,0x81,0xFF,0xA1,0xA6,0xA8,0x3F,0xC8,0xD3,0x00,0xD5,0x80,0xD8,0x05,0xD9,0xF1,0xDA,0x12,0xDB,0x30,0x8D,0x14,0xAF,0x20,0x00};发现使⽤改⽅式刷新SSD1315类型的OLED时会出问题，对其进⾏修改：const uint8_t OLED_Init_CMD[] ={ 0xae,0x00,0x10,0x40,0x81,0xcf,0xa1,0xc8,0xa6,0xa8, 0x3f,0xd3,0x00,0xd5,0x80,0xd9,0xf1,0xda,0x12,0xdb, 0x40,0x20,0x00,0x8d,0x14,0xa4,0xa6,0xaf};⽴刻正常，看来两个⽚⼦的⼯作模式还是有些区别的。

OLED模块使用说明

7.6 系统显示设计控制系统显示常用的显示器件有数码管、LCD、OLED等。

OLED即有机发光二极管(Organic Light Emitting Diode)，其同时具备自发光，不需背光源、对比度高、制程较简单等优异之特性，被认为是下一代的平面显示器新兴应用技术。

本节主要介绍OLED的工作原理、底层驱动代码编写以及如何通过取模软件显示任何自己想要显示的文字或者图片。

7.6.1 OLED显示原理如图4所示为0.96寸OLED显示模块，其分辨率为128*64，采用4线SPI接口方式，模块的接口定义如表1所示。

图4 0.96寸OLED显示模块种并行接口方式、3线或4线SPI接口方式、IIC接口方式。

这里介绍OLED模块4线SPI 通信方式，只需4根通信线就能实现对OLED模块的显示控制，这4根线为：D0、D1、DC、CS。

如图5所示为4线SPI写操作时序图，在4线SPI模式下，每个数据长度均为8位，也即为1个字节。

每次发送该字节数据前，如果该字节数据为指令号，则将DC管脚拉低；如果该字节数据为普通数据，则将DC管脚置高。

在SCLK上升沿，数据从SDIN移入SSD1306，并且高位在前。

SSD1306的显存总共为128*64bit大小，SSD1306将这些显存分为8页，其对应关系如表2所示。

可见OLED水平像素分为128段，即SEG0~SEG127；垂直像素平分为8页，也即垂直方向每8个像素点为1页。

从而可见，在确定显示的位置后，通过往显存中写入一个字节数据，则相应的SEG将按照数据进行显示，位数据为1时，相应像素点被点亮，位数据为0时，相应的像素点熄灭。

图5 4线SPI写操作时序图令较多，具体的可以参考相关手册，这里介绍如表3所示几个比较常用的指令。

命令，随后发送的一个字节为要设置的对比度的值。

这个值设置得越大屏幕就越亮。

第二个命令为 0XAE/0XAF。

0XAE 为关闭显示命令； 0XAF 为开启显示命令。

0.96寸OLED显示屏IIC接口（SSD1306）

0.96⼨OLED显⽰屏IIC接⼝（SSD1306）IIC接⼝引脚分配SSD1306在I2C总线模式下的接⼝分配数据/命令引脚控制引脚[D7:D3]D2D1D0E R/W#CS#D/C#RES#共阴SDA OUT SDA IN SCL共阴SA0RES#IIC通信接⼝由总线的数据信号SDA（SDA OUT和SDA IN）和总线的时钟信号SCL组成。

数据和时钟信号必须连接上拉电阻。

SA0 为从机地址引脚，RES#为设备的初始化引脚。

1.SDA 数据信号线 SDA是主机和从机间进⾏数据收发和应答的通道。

需注意的是，SDA引脚的ITO 电阻和上拉电阻有⼀个潜在的分压，结果就是，SDA线上的应答信号可能达不到有效的低电平。

SDA OUT和SDA IN连接在⼀起由数据信号线SDA引出，SDA IN引脚必须连接以充当SDA。

SDA OUT引脚可能断开。

当SDA OUT引脚断开时，I2C总线中的应答信号将被忽略。

2.SCL 时钟信号线信息在IIC总线中的传输遵循时钟信号SCL。

数据位的每次传输都是在SCL的单个时钟周期内进⾏的。

3.SA0 丛机地址位在IIC总线发送或接收任何信息之前，SSD1306必须先识别从机地址。

设备将响应具有以下字节格式的字节：bit7bit6bit5bit4bit3bit2bit1bit0011110SA0R/W#”D/C#“作为SA0⽤于从地址选择。

SA0位为从机地址提供扩展位。

“0111100”或“0111101”均可作为SSD1306的从机地址。

“R/W#”⽤于确定IIC总线接⼝的操作模式。

R/W#=1，为读取模式。

R/W#=0，为写⼊模式。

写数据I2C总线接⼝允许将数据和命令写⼊设备，以下为I2C总线的写⼊模式按时序图。

IIC总线写⼊数据格式IIC写⼊模式1.主机通过启动条件启动数据通信。

SSD1306（OLED驱动芯⽚）指令详解基础命令:1.页地址模式下设置列起始地址低位(Set Lower Column Start Address For Page Addressing Mode)(00h~0Fh)此指令⽤于在页地址模式下设置GDDRAM的列起始地址(8位)的低4位, 页地址会在数据访问后递增2.页地址模式下设置列起始地址⾼位(Set Higher Column Start Address For Page Addressing Mode)(10h~1Fh)此指令⽤于在页地址模式下设置GDDRAM的列起始地址(8位)的⾼4位, 页地址会在数据访问后递增3.设置内存地址模式(Set Memory Addressing Mode)(20h)在SSD1306中有三种地址模式: 页地址模式, ⽔平地址模式和垂直地址模式, 此命令⽤于将地址模式设置为以上三种之⼀'COL'的含义是GDDRAM列(column)页地址模式(A[1:0]=10b)当处于此模式时, 在GDDRAM访问后(读/写), 列地址指针将⾃动增加1。

如果列地址指针到达列终⽌地址, 列地址指针将复位到列起始地址, 但页地址指针不会改变。

为了访问GDDRAM中下⼀页的内容, ⽤户必须设置新的页地址和列地址。

页地址模式下页以及列地址指针的⾏为如下图所⽰通常在页地址模式下访问GDDRAM, 需要如下步骤来定义起始RAM访问指针指向:-通过命令(B0h-B7h)设置⽬标显⽰位置页起始地址-通过命令(00h-0Fh)设置列起始地址低位-通过命令(10h-1Fh)设置列起始地址⾼位例如, 如果页地址是B2h, 列地址低位是03h, 列地址⾼位是10h, 起始列将为PAGE2的SEG3, GDDRAM访问指针的指向如下图所⽰⽔平地址模式(A[1:0]=00b)当处于此模式时, 在GDDRAM访问后(读/写), 列地址指针将⾃动增加1。

(℃) -30℃~80℃2.We will illustrate the usage of the module with an example of 4-wire SPI mode (defaultworking mode) by connecting Waveshare Open103R development board (STM32V MCU onboard).2.1.Hardware configurationThis module provides 3 kinds of driver interfaces; they are 3-wire SPI, 4-wire SPI and I2C interface. In its factory settings, BS0/BS1 pins are set to 0/0 and 4-wire SPI is selected as default.Different working mode and pin function of the module can be set by hardware selection on BS0/BS1 pins. (Notice: In this operation, welding is required. Any changes under no guidance from Waveshare will be considered as a waiver of warranty).Table 1: Working mode setting122.2.Software configurationOpen the project file .\IDE\ OLED.uvproj in Keil, navigate to the following text, delete the ‘//’ (Double slash) before #define INTERFACE_4WIRE_SPI After compiling successfully, download the project to Open103R development board. Note: You should delete the ‘//’ (Double slash) corresponding to the mode selection2.3. Hardware connectionsConnect module to the SPI2 interface of Open103R development board, power up. OLED displays information as Figure 1 shows.Figure 1: OLED information display3. 4-wire SPI and I2C interfaces of SSD1306 OLEDThis module provides 3 kinds of driver interfaces. We introduce 4-wire SPI and I2C interfaceshere. You can read Chap. 8.1 from SSD1306-Revision_1.1.pdf for more details.The 4-wire serial interface consists of serial clock: SCLK, serial data: SDIN, D/C#, CS#. In 4-wire SPI mode,D0 acts as SCLK, D1 acts as SDIN. For the unused data pins, D2 should be left open. The pins from D3 to D7, E and R/W# (WR#)# can be connected to an external ground.Table 2: 4-wire SPI Control pins of 4-wire Serial interfaceNote(1) H stands for HIGH in signal(2) L stands for LOW in signalSDIN is shifted into an 8-bit shift register on every rising edge of SCLK in the order of D7, D6 0D/C# is sampled on every eighth clock and the data byte in the shift register is written to the Graphic Display Data RAM (GDDRAM) or command register in the same clock.Under serial mode, only write operations are allowed.Figure 2: Write procedure in 4-wire Serial interface modeThe I2C-bus interface gives access to write data and command into the device. Please referto Figure 2 for the write mode of I2C-bus in chronological order.a)Slave address bit (SA0)SSD1306 has to recognize the slave address before transmitting or receiving any information by the I2C-bus. The device will respond to the slave address following by the slave address bit (“SA0”bit) and the read/write select bit (“R/W#” bit) with the following byte format,b7 b6 b5 b4 b6 b2 b1 b00 1 1 1 1 0 SA0 R/W#“SA0” bit provides an extension bit for the slave address. Either “0111100” or3“0111101”, can be selected as the slave address of SSD1306. D/C# pin acts as SA0 for slave address selection. “R/W#” bit is used to determine the operation mode of the I2C-bus interface.R/W#=1, it is in read mode. R/W#=0, it is in write mode.b)I2C-bus data signal (SDA)SDA acts as a communication channel between the transmitter and the receiver. The data and the acknowledgement are sent through the SDA.It should be noticed that the ITO track resistance and the pulled-up resistance at “SDA” pinbecomes a voltage potential divider. As a result, the acknowledgement would not be possible to attain a valid logic 0 level in “SDA””SDAIN” and “SDAOUT” are tied together and serve as SDA. The “SDAIN” pin must be connected to act as SDA. The “SDAOUT” pin may be disconnected. When “SDAOUT” pin is disconnected, the acknowledgement signal will be ignored in the I2C-bus.c)I2C-bus clock signal (SCL)The transmission of information in the I2C-bus is following a clock signal, SCL. Each transmission of data bit is taken place during a single clock period of SCL.Table 3. I2C I2C-bus data format1)The slave address is following the start condition for recognition use. For the SSD1306, the slaveaddress is either “b0111100” or “b0111101” by changing the SA0 to LOW or HIGH (D/C pin acts as SA0).2)The write mode is established by setting the R/W# bit to logic “0”43)An acknowledgement signal will be generated after receiving one byte of data, including theslave address and the R/W# bit.4)After the transmission of the slave address, either the control byte or the data byte may be sentacross the SDA. A control byte mainly consists of Co and D/C# bits following by six “0” ‘s.a)If the Co bit is set as logic “0”, the transmission of the following information will containdata bytes only.b)The D/C# bit determines the next data byte is acted as a command or a data. If the D/C# bitis set to logic “0”, it defines the following data byte as a command. If the D/C# bit is set tologic “1”, it defines the following data byte as a data which will be stored at the GDDRAM.The GDDRAM column address pointer will be increased by one automatically after eachdata write.5)Acknowledge bit will be generated after receiving each control byte or data byte.5。
