(℃) -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。

2、模块用途
OLED，即有机发光二极管（ 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、可用于挠曲性面板、使用温度范围广、构造及制程较简单等特性，被认为是下一代的平面显示器新兴应用技术。
3.3 模块的电源电路设计
SSD1306 的电源有 VCC：显示屏工作电压；VDD：逻辑电路工作电压。VCC 的工作电压比较高，但是有两种供电方式：第一种是外部给 VCC 供电，电压范围 8.5V~9.5V；第二种是使用 SSD1306 的内部 DC/DC 电路生成的电压对 VCC 进行供电，供电范围 7.0V~7.5V（可参考官方手册 2、3.2 部分内容）。一般的系统的工作电压是 3.3V 或 5V，所以电源电路设计采用 SSD1306 的内部 DC/DC 设计（可参考官方手册 1.62、部分内容），VCC 由内部的 DC/DC 电路供电，只需要给 VBAT 与 VDD 供电，供电电压为 3.3V。

0.96寸OLED液晶屏模块

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。

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.

中景园电子0.96OLED显示屏_模块说明书
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 的响应时间大约是几十毫秒，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。

OLED显示模块驱动原理及应用

OLED显示模块驱动原理及应用本文以中景园OLED显示模块为例，介绍模块的应用和OLED显示及驱动的基本原理。

文中介绍了显示模块、SSD1306驱动芯片以及GT20L16S1Y字库芯片相关技术内容及原理，并加上了作者的理解和应用记录。

一、模块介绍1. OLED显示屏基础显示屏的发光单元是有机聚合物发光二级管，即organic/polymer light emitting diode，简称 OLED。

单色屏的一个像素就是一个发光二极管。

OLED是“自发光”，像素本身就是光源，所以对比度极高，显示效果很犀利，绝无朦朦胧胧、拖泥带水之感，深受爱好者追捧，可惜当前技术所限，无法大尺寸化，价格也比TFT 液晶屏高得多。

OLED分PMOLED、AMOLED两种，PMOLED为无源驱动，AMOLED为有源驱动。

本文介绍的模块显示屏为PMOLED。

2. 模块基本信息模块外观如图1，型号为QG－2864KLBEG01，尺寸见图2。

本模块显示颜色为1/4黄+3/4蓝，但仍属于单色屏，另有“蓝+白”组合色可选。

模块接口为8个插针，针脚定义已印在板上，使用串行SPI 协议。

因为板载稳压芯片U2，模块供电电压可以是3－5V。

模块自带中文字库芯片。

图1.模块正面及反面图2.模块尺寸图3. 模块器件及元件简介1) OLED显示屏：128*64点阵OLED单色屏。

下文简称为显示屏、屏、OLED屏。

2) SSD1306驱动芯片：模块上直接看不到，芯片封装在显示屏背面玻璃基板上。

3) GT20L16S1Y字库芯片：内部固化了8套字符的点阵数据，90%的容量都用来存储中文字库。

4) 接口及电源配置电路：8路插针，板载低压差降压稳压芯片662K。

5) PCB板及若干外围电阻电容元件。

模块厂家已做好外围电路，不用再操心硬件电路。

4. 模块电路图图3、模块电原理图供电：模块供电输入端为VCC_IN，经U2降压后供U1、U4等电路。

OLED屏驱动需要7－7.5V电压，由SSD1306内置电荷泵升压后提供。

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。

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。

图 2.3.1 SSD1306 中 GDDRAM 页的机构
图 2.3.1 中端口 COM 和端口 SEG 与 GDDRAM 的对应关系是可以软件设置的。在软件设置的时候用到这个函数：OLED_WCMD(u8 cmd);//向 SSD1306 写命令。这里不详细介绍，在程序设计中详细介绍。当写入一个字节到 GDDRAM 时，这字节又是怎么存储的呢，请看 2.3.2：每一个 Bit 存储在一个方格中，再看红色圈出部位，每个方格代表着每个像素点，这样， GDDRAM 和像素点之间就构成了联系。

PmodOLEDrgb 96×64像素RGB有机LED模块说明书

1300 Henley Court Pullman, WA 99163509.334.6306 PmodOLEDrgb ™ Reference ManualRevised April 26, 2016This manual applies to the PmodOLEDrgb rev. BOverviewThe Digilent PmodOLEDrgb is an organic RGB LED module with a 96×64 pixel display capable of 16-bit color resolution.1 Functional DescriptionThe PmodOLEDrgb utilizes a Solomon Systech SSD1331 display controller to receive information from the host board and display the desired information on the OLED screen.2 Interfacing with the PmodThe PmodOLEDrgb communicates with the host board via the SPI protocol. By driving and keeping the Chip Select (CS) line at a logic level low, users may send both commands and data streams to the display controller based on the state of the Data/Command (D/C) pin.The PmodOLEDrgb.∙ 96×64 pixel RGB OLED screen ∙ 0.8“ x 0.5” graphical display ∙ 16-bit color resolution∙ Two low-power display shutdown modes ∙ Small PCB size for flexible designs (1.4“ x 1.0”)∙ 12-pin Pmod connector with SPI interface ∙ Library and example code available in resource centerFeatures include:As a graphical display interface, users may light up any individual pixel on the OLED, display predefined characters, or even load bitmaps onto the screen. Each pixel can be set to one of the 65,535 colors that are available. The OLED display has a specific power-up and power-down sequence to ensure the longevity of the device.There are two field-effect transistors (FETs) that control the display’s two power supplies. The VCCEN control toggles the positive voltage supply to the screen itself and the PMODEN control toggles the power supply ground to the display. Users may turn off either one of these controls to reduce the power consumption of the PmodOLEDrgb to approximately 200 nA.2.1 Power-on Sequence1.Apply power to VCC.2.Send Display Off command.3.Initialize display to default settings.4.Clear screen.5.Apply power to VCCEN.6.Delay 100ms.7.Send Display On command.2.2 Power-off Sequence1.Send Display Off command2.Power off VCCEN3.Delay 100ms4.Power off VCCA pinout table of the PmodOLEDrgb is provided below.Pin Signal Description1 CS Chip Select2 MOSI Master-Out-Slave-In3 NC Not Connected4 SCK Serial Clock5 GND Power Supply Ground6 VCC Power Supply (3.3V)7 D/C Data/Command Control8 RES Power Reset9 VCCEN Vcc Enable10 PMODEN Vdd Logic Voltage Control11 GND Power Supply Ground12 VCC Power Supply (3.3V)Table 1. Header J1 pinout descriptions.Although users are welcome to create their own interface code for the PmodOLEDrgb if they so desire, pre-constructed libraries that provide functions for initializing the display and rendering simple text and graphics onto the screen exist. They are available on the PmodOLEDrgb example code page and can be used as-is or as a starting point for a more sophisticated graphics library.Any external power applied to the PmodOLEDrgb must be within 2.7V and 5V; however, it is recommended that Pmod is operated at 3.3V.3 Physical DimensionsThe pins on the pin header are spaced 100 mil apart. The PCB is 1.4 inches long on the sides parallel to the pins on the pin header and 1 inch long on the sides perpendicular to the pin header.。

中景园电子0.96寸OLED使用文档新手必看V2.0

0.96寸OLED显示屏使用手册一、OLED简介OLED，即有机发光二极管（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、可用于挠曲性面板、使用温度范围广、构造及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。

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，蓝三种颜色可选；其中黄蓝是屏上1/4部分为黄光，下3/4为蓝；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；蓝色则为纯蓝，也就是黑底蓝字。

2）分辨率为128*643）多种接口方式；OLED裸屏总共种接口包括：6800、8080 两种并行接口方式、3线或4 线的串行SPI 接口方式、IIC 接口方式（只需要 2 根线就可以控制OLED 了！），这五种接口是通过屏上的BS0~BS2来配置的。

4）中景园电子的本屏开发了两种接口的Demo板，接口分别为七针的SPI/IIC兼容模块，四针的IIC模块。

两种模块都很方便使用；希望大家根据实际需求来选择不同的模块。

二、产品特点2.1 0.96寸OLED裸屏外观裸屏为30pin，从屏正面看左下角为1，右下角为30；在设计的时候一定要注意不要搞反了。
