e-Paper is Here!
Question: What’s so special about e-Paper? Answer: The key to e-paper is low power. e-Paper Displays Are A Low Power Solution If your project needs a very low-power display solution, a zero-power ePaper display is the answer. First designed to mimic the appearance of black ink on white paper, these electrophoretic display modules are sometimes referred
Tutorial: Driving a 144×32 Graphic LCD
We have published a sample Arduino Sketch that shows how to drive a Sitronix ST7920 based CFAG14432D 144×32 Graphic LCD in our support forum. With just a few primitive functions, you can create some nice looking displays. We used a Seeeduino v4.2. An Arduino Uno would work just as well. Here is a video overview of

The Legendary HD44780 Controller
Modern Character LCD display modules have been possible since 1987 when Hitachi introduced the HD44780 LCD controller. Since then, Hitachi no longer manufactures this integrated circuit (IC), but modern LCD controller ICs make it a point to be HD44780-compatible. Controller Compatibility The character LCD display modules offered by Crystalfontz America Inc. are no exception to

Engineering and Art
Engineers are known for their curious and typically black-and-white way of thinking. They tackle the tough problems. They love math. Order and matching rule. Their art is usually defined by measurable parameters — CAD drawings, tracings, and placements of resistors. Crystalfontz electrical engineer Brent recently did some mosaic artwork, inspired by his wife who enjoys
