Update 2015-09-10: I also added a timer 2 based version of the driver which does not need any manual refresh.

I created a fast and compact driver for the Sharp memory display LS013B4DN04. The driver is text based and uses 8×8 pixel characters on the screen. The screen can display 12×12 characters using this size of characters.

Demo

This demo is an example of the Arduino library.

Features

• Uses only 174 bytes of dynamic memory.
• Refreshes only changed rows on the screen.
  This speeds up the refresh process and makes the refresh method suitable to call it from an interrupt.
• Each character on the screen can be displayed normal or inverted. Ideal to mark a row in a menu.
• Fonts can provide up to 128 characters. The font can be changed at any time.
• Minimal but complete API with direct character access, cursor based write methods and scrolling of the display in four directions.
• Open Source
