(℃) -20℃~70℃Storage Temp. (℃) -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。

信意电子0.96寸OLED模块说明书目录一、OLED技术特点 (2)二、OLED模块介绍 (2)三、0.96寸OLED模块特点 (5)四、管脚定义 (5)五、客户应用案例 (6)一、OLED技术特点（1）OLED器件的核心层厚度很薄，厚度可以小于1mm，为液晶的1/3。

（2）OLED器件为全固态机构，无真空，液体物质，抗震性好，可以适应巨大的加速度，振动等恶劣环境。

（3）主动发光的特性使OLED几乎没有视角限制，视角一般可达到170度，具有较宽的视角，从侧面也不会失真。

（4）OLED显示屏的响应时间超过TFT—LCD液晶屏。

TFT—LCD的响应时间大约使几十毫秒，现在做得最好的TFT—LCD响应时间也只有12毫秒。

而OLED显示屏的响应时间大约是几微秒到几十微秒。

（5）OLED低温特性好，在零下40摄氏度都能正常显示，目前航天服上也使用OLED作为显示屏。

而TFT—LCD的响应速度随温度发生变化，低温下，其响应速度变慢，因此，液晶在低温下显示效果不好。

（6）OLED采用有机发光原理，所需材料很少，制作上比采用液体发光的液晶工序少，液晶显示屏少3道工序，成本大幅降低。

（7）OLED采用的二极管会自行发光，因此不需要背面光源，发光转化效率高，能耗比液晶低，OLED能够在不同材质的基板上制造，厂家甚至可以将电路印刷在弹性材料上——做成能弯曲的柔软显示器。

（8）低电压直流驱动，5V以下，用电池就能点亮。

高亮度，可达300明流以上。

二、OLED模块介绍：1、OLED模块显示效果图：图一：蓝色0.96寸OLED显示效果图二：白色0.96寸OLED显示效果图三：黄蓝双色0.96寸OLED显示效果0.96寸OLED屏幕详细尺寸：信意电子的0.96寸OLED模块采用高亮度，低功耗的OLED屏，显示颜色纯正，在阳光下有很好的可视效果。

Note that the resolution of this LCD module is 160(H)RGBx80(V) indeed.ST7735S supports RGB444, RGB565 and RGB666 three formats. This LCD module we use RGB565.Because that the first pixel of the LCD is different with the origin point of controller, therefore, we should offset the position when initialize the module: Horizontal: begin from the second pixel; Vertical: begin from the 27th pixel. Make sure that the display position of LCD is same as RAM.For most of the LCD controller, there are several interfaces for choosing, this module we use SPI interface which is fast and simple.COMMUNICATION PROTOCOLNote: It is not like the tradition SPI protocol, it only uses MOSI to send data from master to slave for LCD display. For details please refer to Datasheet Page 105. RESX: Reset, should be pull-down when power on, set to 1 other time.CSX: Slave chip select. The chip is enabled only CS is set LowD/CX: Data/Command selection; DC=0, write command; DC=1, write dataSDA: Data transmitted. (RGB data)SCL: SPI clockThe SPI communication protocol of the data transmission uses control bits: clock phase (CPHA) and clock polarity (CPOL):CPOL defines the level while synchronization clock is idle. If CPOL=0, then it is LOW. CPHA defines at wh ish clock’s tick the data transmission starts. CPHL=0 – at the first one, otherwise at the second oneThis combination of two bits provides 4 modes of SPI data transmission. The commonly used is SPI0 mode, i.e. GPHL=0 and CPOL=0.According to the figure above, data transmitting begins at the first falling edge, 8bit data are transmitted at one clock cycle. It is SPI0.

0.96寸OLED介绍第二讲

0.96寸OLED显示屏介绍0.96 寸OLED 显示屏使用方法（以中景园电子的0.96 寸OLED 显示屏为例）0.96寸OLED显示屏实物图七针SPI/IIC 0.96寸OLED显示屏使用方法：七针SPI/IIC 0.96寸OLED显示屏共有七个管脚，1～7 分别为GDN、VCC、D0、D1、RES、DC、CS。

此模块支持四线SPI、三线SPI、IIC 接口。

0.96寸OLED显示屏裸屏是支持五种不同接口的，除了前面的三种还有6800、8080 并口方式；由于这两种接口占用数据线比较多；而且不太常用，所以模块在设计的时候没有引出来。

模块的通信接口是通过BS0,BS1,BS2三个管脚来配置的。

在SPI 接口中，R1,R2,R8 三个电阻是不焊接的。

在IIC 接口中，需要将R3换到R1上，R8 可以焊接也可不焊接。

七针SPI/IIC 0.96寸OLED显示屏正面丝印如下，如果想用IIC接口，在IIC接口中需要将RES接高电平，可以与VCC对接,使OLED复位脚一直操持高电平，也就是不复位的状态；同时需要将DC,CS 接电源地；IIC 通信中只需要GND ,VCC,D0(时钟信号)，D1(数据信号)四根线。

如果感觉比较麻烦；也可以直接选用四针的IIC接口的0.96寸OLED显示屏。

四针IIC接口相对比较简单一些，只有两个信号线。

1、GND：电源地。

2、VCC：电源正（3～5.5V）。

3、SCL：OLED 的D0 脚，在IIC 通信中为时钟管脚。

4、SDA：OLED 的D1 脚，在IIC 通信中为数据管脚。

0.96寸)LED模块IIC控制

Write mode for I2C1)The master device initiates the data communication by a start condition. The definition ofthe startcondition is shown in Figure 8-8. The start condition is established by pulling the SDA from HIGH toLOW while the SCL stays HIGH.1)主设备通过一个启动条件启动数据通信。

开始条件的定义如图8-8所示。

启动条件是通过将SDA从高到低，而SCL保持高位时建立的。

2) 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 asSA0).2)从机地址在开始条件下进行识别使用。

对于SSD1306，通过将SA0更改为低或高(d/c pin为SA0)，该从属地址是“b0111100”或“b0111101”。

2)The write mode is established by setting the R/W# bit to logic “0”.3)An acknowledgement signal will be generated after receiving one byte of data, includingthe slaveaddress and the R/W# bit. Please refer to the Figure 8-9 for thegraphicalrepresentation of theacknowledge signal. The acknowledge bit is defined as the SDA line is pulled down during the HIGHperiod of the acknowledgement related clock pulse.5) After the transmission of the slave address, either the control byte or the data byte may be sent acrossthe 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.如果将Co位设置为逻辑“0”，那么以下信息的传输将仅包含数据字节。

0.96寸oled显示屏测试标准

0.96寸OLED显示屏的测试标准主要包括以下几个方面：
尺寸检测：使用测量工具对显示屏的实际尺寸进行测量，看是否符合设计要求。

显示效果测试：检查显示屏的亮度、对比度、色彩还原、视角等是否达到设计要求。

可以通过播放不同的测试图像，如灰度图、彩色图等来进行测试。

驱动测试：检查显示屏的驱动电路是否正常工作，包括驱动电压、电流等参数的检测。

寿命测试：对显示屏进行长时间工作测试，检查显示屏在长时间工作下的性能衰减情况。

温度测试：在不同温度下对显示屏进行测试，检查显示屏在高温和低温环境下的性能表现。

抗干扰能力测试：对显示屏进行电磁干扰测试，检查显示屏的抗干扰能力。

环境适应性测试：对显示屏进行恶劣环境下的测试，如防尘、防水等。

通过以上方面的测试和检测，可以全面评估0.96寸OLED显示屏的性能和品质，确保其符合设计要求和用户需求。

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
一、OLED简介
OLED，即有机发光二级管(Organic Light Emitting Diode)。

OLED由于同时具备自发光，不需背光源、对比度高、厚度薄、视角广、反应速度快、可用于扭曲性面板、使用温度范围广、构造及制作较简单等优异的特性，被认为是下一代的平面显示器新兴应用技术。

LCD都需要背光，而OLED不需要，因为它是自发光的。

这样同样的显示，OLED效果要来得好一些。

以目前的技术，OLED的尺寸还难以大型化，但是分辨率确可以做到很高。

在此我们使用的是中景园电子的0.96寸OLED显示屏，该屏有以下特点：
1、0.96寸OLED有黄蓝、白、蓝三种颜色可以选择，其中黄蓝是屏上1/4部分为黄光，下3/4位蓝光，而且是固定区域显示固定颜色，颜色和显示区域均不能修改。

白光则为纯白，也就是黑底白字。

蓝光则为纯蓝，也就是黑底蓝字。

2、分辨率为128*64，每个像素都是一个LED。

3、多种接口方式，OLED裸屏的接口方式有5种：6800、8080两种并行接口方式、3线或4线的串行SPI接口方式、I2C接口方式(只需要用到2根线就可以控制OLED了！)，这5种接口方式是通过屏上的BS0~BS2来配置的。

4、中景园电子的屏开发了两种接口的DEMO板，接口分别为七针的SPI/I2C兼容模块，四针的I2C模块，两种模块都很方便使用，我们可以根据实际需求来选择不同的模块。

二、模块特点：
1、0.96寸OLED裸屏外观
裸屏为30Pin，从屏正面看左下角为1脚，右下角为30脚。

在设计的时候一定要注意不要弄反了。

具体的接口方式请大家查看0.96寸OLED官方数据手册，里面有详细介绍。

2、0.96寸OLED模块
(1)SPI/I2C接口模块(7脚)
(2)I2C接口模块(4脚)
3、0.96寸OLED的驱动IC芯片(SSD1306)
本屏所用的驱动IC芯片为SSD1306，其具有内部升压功能，所以在设计的时候就不需要再专门设计升压电路了。

当然本屏也可以选用外部升压，具体请详细查阅数据手册。

SSD1306的每页包含了128个字节，总共8页，这样刚好是128*64的点阵大小，这点和1.3寸OLED 驱动IC芯片SSD1106稍有不同，SSD1106每页是132个字节，也是8页，所以在用0.96寸OLED移植1.3寸OLED程序的时候需要将0.96寸的显示地址向右偏移2，这样显示才正常，否则在用1.3寸的时候1.3寸屏右边会有4个像素点宽度显示不正常或者是全白，这点大家需要注意一下，其他的SSD1306和SSD1106区别不大。

三、0.96寸OLED模块使用方法：
1、SPI/I2C接口模块(7脚)使用方法
硬件上就是在单片机上选择四个普通IO口充当D0、D1、RES和DC，再连接OLED上的相应接口，VCC接3.3或5V，GND接电源负极。

程序上就选择相应的7脚的SPI驱动OLED 的例程，修改管脚，调用过OLED初始化函数后就可以使用OLED的一些API函数了。

2、I2C接口模块(4脚)使用方法
硬件上就是单片机上选择两个普通IO口充当SCL和SDA，再连接上OLED上的相应接口，当然用硬件I2C也是可以的，不过要修改OLED的驱动库函数，VCC接3.3或5V，GND接电源负极。

程序上就选择相应的4脚的I2C驱动OLED的例程，修改管脚，调用过OLED初始化函数后就可以使用OLED的一些API函数了。

四、如何让SPI/I2C接口模块(7脚)从SPI接口切换到I2C接口。
