Detailed Description

• ID: ssd1327
• Name: OLED Display
• Other Names: Grove OLED Display 1.12"
• Category: display
• Manufacturer: seeed adafruit
• Link: http://wiki.seeed.cc/Grove-OLED_Display_1.12inch/
• Connection: i2c

SSD1327 is a 96x96 dot-matrix OLED/PLED segment driver with a controller. This implementation was tested using the Grove LED 96*96 Display module, which is an OLED monochrome display.

        upm_i2clcd.SSD1327 lcd = new upm_i2clcd.SSD1327(0);

        // If you don't set the display to be white, the seeed logo will appear
        // jagged
        lcd.setGrayLevel((short) 12);

        byte[] image = new byte[SeeedLogo.length];
        for (int i = 0; i < SeeedLogo.length; i++)
            image[i] = (byte) SeeedLogo[i];

        lcd.draw(image);

        // Simple print hello world
        for (short i = 0; i < 12; i++) {
            lcd.setCursor(i, 0);
            lcd.setGrayLevel(i);
            lcd.write("Hello World");
        }
