0.96inch OLEDUser Manual 1.Driver Chip SSD1306Interface 3-wire SPI、4-wire SPI、I2CResolution 128x64Display Size 0.96 inchDimension 29mm*33mmColors Yellow, BlueVisible Angle >160°Operating Temp. (℃) -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。

0.91inch OLED ModuleUser ManualOVERVIEWThis is a general OLED display Module, 0.91inch diagonal, 128x32 pixels, with embedded controller, communicating via I2C interface.FEATURESController: SSD1306Interface: I2CResolution: 128*32Display Size: 1.5inchDisplay Color: WhiteOperating Voltage: 2.2V/5VPINSPIN DescriptionVCC PowerGND GroundSDA Data inputSCL Clock inputWORKING PROTOCOLSSD1306 is a controller for 128*64 OLED. This OLED has only 128*32 pixels, so it uses part of SSD1306’s buffer.In theory, the OLED supports 8-bit 8080, 8-bits 6800, 3-wires SPI, 4-wires SPI and I2C, however, to save IO resources and because of the small size of OLED, we only pinout I2C interface.I2C COMMUNICATIONWhen working, MCU will first send a byte that the first 7bits are address of slave device and 1 bit write/read bit, and wait for response.After received response from slave device, MCU will send a control byte, this byte defined the data following is command or data.Slave response again, if sending command, MCU will send the command which is one byte. If sending data, MCU will sending dataFor more details about I2C, please refer to Datasheet Page20 Figure 8-7We provide STM32, Arduino and Raspberry Pi demo code for this module.

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.
