hiletgo 1.3 spi 128x64 ssh1106 oled lcd display lcd module factory

ER-OLED013-1W is the graphic OLED display module made of 128x64 white OLED pixels,diagonal is only 1.3 inch.The controller ic SSD1306, communicates via 6800/8080 8-bit parallel and I2C/3-wire/4-wire serial interface,thanks to controller"s built-in voltage generation,only a single 3.3V power supply is needed. Because the display makes its own light, no backlight is required. This reduces the power required to run the OLED and is why the display has such high contrast,extremely wide viewing angle and extremely operating temperature.

The SSD1306/SSH1106 are a single-chip CMOS OLED/PLED driver with controllers for organic/polymer light emitting diode dot-matrix graphic display system. It consists of 128 segments and 64 commons. This IC is designed for Common Cathode type OLED panel.

The OLED module provides three drive interfaces: 3-wire SPI, 4-wire SPI, and I2C interface respectively. There are two resistors that can be soldered on the back of the module. The corresponding communication method is selected by the electronic selection, as shown in the figure:

The module uses the 4-wire SPI communication mode by default, that is, BS0 and BS1 are connected to 0 by default (1 and 0 do not represent the level, but the resistance is connected or connected to the welding method, the specific hardware link is shown in the table below):

PS: The program defaults to SPI mode. If you need to switch the mode, please modify DEV_Config.h. For details, please refer to the program description - bottom hardware interface - interface selection

After the compilation is complete, the main file is generated, enter the command according to the OLED model you are using. If you have purchased a 1.3inch OLED Module (C), please enter the following command:

If you need to draw pictures, display Chinese and English characters, display pictures, etc., we provide some basic functions here about some graphics processing in the directory RaspberryPi\c\lib\GUI\GUI_Paint.c(.h).

Set points of the display position and color in the buffer: here is the core GUI function, processing points display position and color in the buffer.

The fill color of a certain window in the image buffer: the image buffer part of the window filled with a certain color, usually used to fresh the screen into blank, often used for time display, fresh the last second of the screen.

Display time: in the image buffer,use (Xstart Ystart) as the left vertex, display time,you can choose Ascii visual character font, font foreground color, font background color.;

2. The module_init() function is automatically called in the INIT () initializer on the LCD, but the module_exit() function needs to be called by itself

Python has an image library PIL official library link, it do not need to write code from the logical layer like C, can directly call to the image library for image processing. The following will take 1.54inch LCD as an example, we provide a brief description for the demo.

Note: Each character library contains different characters; If some characters cannot be displayed, it is recommended that you can refer to the encoding set ro used.

The examples are based on STM32F103RBT6 as well as the connection table. If you want to use other MCU, you need to port the project and change the connection according to the actual hardware.

For examples, if you are using 1.3inch OLED Module （C）,you need to comment out the line 105. (Note: there cannot be multiple sentences without comment at the same time; the line number may be changed, please modify it according to the actual situation)

The demo is developed based on the HAL library. Download the demo, find the STM32 program file directory, and open the oled_demo.uvprojx in the STM32\STM32F103RBT6\MDK-ARM directory to check the program.

In addition, you can see the file directory of the project in the STM32\STM32-F103RBT6\User\ directory. The five folders are the underlying driver, sample program, font, GUI, and OLED driver.

For the screen, if you need to draw pictures, display Chinese and English characters, display pictures, etc., you can use the upper application to do, and we provide some basic functions here about some graphics processing, you can check in the directory STM32\STM32F103RB\User\GUI\GUI_Paint.c(.h).

The fill color of a certain window in the image buffer: the image buffer part of the window filled with a certain color, usually used to fresh the screen into blank, often used for time display, fresh the last second of the screen.

Display time: in the image buffer, use (Xstart Ystart) as the left vertex, display time, you can choose Ascii visual character font, font foreground color, or font background color.

Choose the folder according to the LCD model you are using, and open the xxx.ino file. Take the 1.3inch OLED Module (C) as an example: open OLED_1in3_c, then double-click OLED_1in3_c.ino to open the Arduino project.

For the screen, if you need to draw pictures, display Chinese and English characters, display pictures, etc., you can use the upper application to do, and we provide some basic functions here about some graphics processing in the directory STM32\STM32F103RB\User\GUI\GUI_Paint.c(.h)

Display time: in the image buffer,use (Xstart Ystart) as the left vertex, display time,you can choose Ascii visual character font, font foreground color, font background color.

The OLED module is used in a 3.3V system by default, but after more than 24 hours of burn-in test, it is found that it can also work normally in a 5V system.
