12864B V 2.0 Graphic Blue Color Backlight LCD Display

12864B V 2.0 Graphic Blue LCD Display

The 12864B V 2.0 Graphic Blue LCD Display. A fairly popular controller used for Arduino. This display works on SPI. It is easy to use and compatible with the majority of microcontrollers out there. You can do a lot of graphics stuff with this display. You can create frames and even make small animations.
Note that the displays expect individual pixels to be turned ON/OFF. It does not support ASCII Inputs like the character display. It may sound like a disadvantage but it is not. It can be used to create beautiful fonts of any sizes you need. You need to store these fonts in the microcontroller and send then to the display. We have tutorials that can help you do this fairly easily.
The 12864B V 2.0 Graphic Blue LCD Display. The display is fully programmable and can display a combination of both graphics and text. It can operate in both parallel and serial (SPI) modes which can be configured by the external pin PSB. In SPI mode only 3 data pins are required to drive this display.
This 12864B LCD is a big, bold, beautiful blue LCD with white back-lit pixels. It is also well known for its wide use in 3D Printers, an extension accessory of RAMPS.If you want to add some visual output to your Arduino projects, you’ll need a display. This LCD display is best suited the graphical upgrade to those popular 16×2 LCDs but allows full graphical control.
In addition to writing text, this graphic 12864B LCD series allows the user to draw lines, circles, and boxes, set or redefine individual pixels, clear specific blocks of the display, backlight control, and adjustment of the baud rate. The LCD 12864b (128×64) Graphic Blue Color Backlight LCD Display module has its pins which are documented on the back of the LCD to assist in wiring it up. It is very easy to interface this LCD with RAMPS controller of the 3D printer.
