View source for KS0532 Keyestudio 1.3 128x64 OLED Display with IIC Ports

== Description ==

<br>[[File:0532-1.png|500px|frameless|thumb]]<br>


OLED is an organic light-emitting diode, also known as organic dot laser display. Composed of a very thin coating of organic materials that emit light and a glass substrate, it has self-luminous properties, a large viewing angle and low power consumption. <br>
It doesn’t need a backlight ( it will light up when the driver and wiring up are correct). <br>
It has high contrast and fast response speed, applied for flexible surface. In addition, it is easy to build. <br>
The module comes with 4 positioning holes, which is convenient for you to fix it on other devices.<br>





== Specification ==

* Working voltage: DC 3.3V-5V 
* Working current: 30mA 
* Interface: pin header interface with a pitch of 2.54mm 
* Communication method: I2C communication 
* Internal driver chip: SSD1306 
* Resolution: 128*64 
* Viewing angle: more than 150° 
* Size: 33*35*3mm 
* Hole spacing: 30.5mm (length) 29mm (width) 
* Weight: 7.1g

== Test Code == 

(Arduino1.8.2）

<pre>
#include <SPI.h>
#include <Wire.h>
#include <Adafruit_GFX.h>
#include <Adafruit_SSD1306.h>

#define SCREEN_WIDTH 128 // OLED display width, in pixels
#define SCREEN_HEIGHT 64 // OLED display height, in pixels

#define OLED_RESET 4
Adafruit_SSD1306 display(SCREEN_WIDTH, SCREEN_HEIGHT, &Wire, OLED_RESET);

void setup() {

// by default, we'll generate the high voltage from the 3.3v line internally! (neat!)
display.begin(SSD1306_SWITCHCAPVCC, 0x3C); // initialize with the I2C addr 0x3D (for the 128x64)
// init done

// Show image buffer on the display hardware.
// Since the buffer is intialized with an Adafruit splashscreen
// internally, this will display the splashscreen.
// Clear the buffer.
display.clearDisplay();
}

void loop() {

display.clearDisplay();
display.setTextSize(1);
display.setTextColor(WHITE);
display.setCursor(0,0);
display.println(F("Hello,world!"));
display.println(F("Hello,keyestudio!"));
display.setTextSize(2);
display.println(F("Hello!"));
//display.println(F("keyes!"));
display.println(F("keyestudio"));
display.display();
delay(250);
}

</pre>


'''Attention：<br>
The library file is used in the code. <br>
Before uploading the test code, you need to copy the library folder to the libraries folder of the Arduino software, as shown below; <br>'''
