Crowbits-OLED

Description¶

Crowbits- OLED is constructed from 128 x 64 dot matrix OLED module. The display offers high brightness, self-emission, high contrast ratio, slim/thin outline, wide viewing angle, wide temperature range and low power consumption.

Features¶

• Low power consumption

Specification¶

• Display Color: Blue
• Resolution: 128x64
• Interface Type: I2C
• Operating Voltage: 3.3V DC
• Dimensions: 56(L)*31(W)*13(H)mm

Usage¶

The following sketch demonstrates a simple application of the module.

1. You need to prepare a Crowbits motherboard, such as Crowbits-UNO board.

2. Connect the module to the I2C interface on the Crowbits-UNO board, as shown in the figure:

3. The following sketch demonstrates a simple application of the module.

4.Connect the module to the I2C interface on the Crowbits-UNO board, as shown in the figure:

#include "U8glib.h"
U8GLIB_SSD1306_128X64 u8g(U8G_I2C_OPT_NONE);  

void drawURL(void)
{
   u8g.setFont(u8g_font_9x18);
   u8g.drawStr(25,10,"Elecrow");
   u8g.setFont(u8g_font_7x14);
   u8g.drawStr(5,35,"www.elecrow.com");

}
void setup(void) {
}

void loop(void) {
  // picture loop
  u8g.firstPage();  
  do {
    drawURL();
  u8g.setColorIndex(1);
  } while( u8g.nextPage() );  
  // rebuild the picture after some delay
  delay(200);  
}
