1.5 lcd module free sample

This 128x128 resolution graphic OLED is ideal for quick and easy prototyping. The OLED module is breadboard friendly, Arduino ready, and has built-in logic level shifting for 3.3V to 5V operation. This self-illuminating display presents full color graphics on a black background. With this OLED you can expect top speed response times and high contrast images from any angle. This RoHS compliant display has serial interface compatibility, a built-in SSD1351 controller, and a microSD card reader.

This is a general RGB OLED display Module, 1.5inch diagonal, 128x128 pixels, 16-bit high color (65K colors), with embedded controller which communicates over a SPI interface.

This is a general RGB OLED display Module, 1.5inch diagonal, 128x128 pixels, 16-bit high color (65K colors), with embedded controller, communicating via SPI interface.

Note:if you’re using a module with a DHT sensor, it normally comes with only three pins. The pins should be labeled so that you know how to wire them. Additionally, many of these modules already come with an internal pull up resistor, so you don’t need to add one to the circuit.

There are a number of options for displaying text or graphics in your project. LEDs and LCDs are the traditional choices but in recent years another type of display has been getting a lot of attention – the OLED.

In the 1950s it was discovered that some organic compounds exhibited the phenomena of electroluminescence. At the time this was not much more than a laboratory curiosity.

Currently, OLEDs are more expensive to manufacture. This will likely change as more factories produce them. Eventually, they will rival or beat LCDs in value, but right now they are more expensive.

The Waveshare 1.5 inch display module is a monochrome 128 x 128 OLED display that can use either an I2C or SPI interface.  Connections can be made to the module using an included cable that mates with a connector on the module itself. There are also holes for header pins to make the same connections if you prefer.

A surface-mount resistor can be moved between solder pads to select either the I2C or SPI connection. When the connection mode changes so do the functions of certain interface pins, a diagram is printed on the back of the module that illustrates this.

I used the supplied cable to hook up the OLED display to my Arduino, you can also solder header pins to the module and plug it into a breadboard if you prefer. Either way the connections are the same, as follows:

You can’t use the Adafruit demos with this display, even when wired in SPI mode. The Waveshare 1.5 inch OLED display uses the SSD1327 driver, which is a different beast than the SSD1306 driver used in the I2C displays we looked at previously.

I visited theWaveshare Wiki for the 1.5 inch OLED Moduleto get some sample software.  They sent me to the (amusingly misspelled)1.5inch OLED Moudle download page.  I downloaded and unzipped the file.

The cost of OLEDs is continually falling and it won’t be too long before they rival LCDs in price. They don’t need a backlight and they are visible in all types of lighting environments.

OLED displays are bright, lightweight and easy to read in almost any lighting environment. In this article, you"ll learn how OLEDs differ from regular LEDs and LCDs and how to use them with an Arduino.

The built-in driver used by this OLED is SSD1351, which is a 128RGB * 128 Dot Matrix OLED/PLED controller with a 128*128*18bit SRAM as a display buffer area, which supports two color depths of 262k and 65k. And supports 8bit 8080 parallel, 8bit 6800 parallel, 3wire-SPI and 4wire-SPI and other communication methods.

This module selects 4wire-SPI and 3wire-SPI as the communication method, which reduces the area of the module and saves the IO resources of the controller.

When DC is set to 1, the transmitted bytes will be stored in the designated register or SRAM of SSD1351 as data. When sending data, multiple bytes can be sent in succession.

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:

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.

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)

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.
