Jason Eppink of the Museum of the Moving Image in Astoria New York has been working on a great little project that shows subtitles on an external Crystalfontz LCD, while the video plays on a monitor above. The project is open source on GitHub. Project Details It uses a Raspberry Pi to play the videos. … Read more Crystalfontz in the movies? Well, almost!
Passive STN (Super Twisted Nematic) displays come in three major types: Segment Alphanumeric / Character Graphic Let’s take a closer look at these 3 types of displays. What are Passive STN Segment, Alphanumeric, and Graphic Displays? Segment LCDs A segment display is the type of thing you see in gas pumps, calculators, or simple meters. … Read more Types of Passive STN LCD Displays
This black and white 200×200 e-paper display module is a perfect size for small, low power electronic shelf labels. Once the epaper’s eink image is shown, it remains visible with zero additional power! These e-Paper displays will retain the last image shown on their screen indefinitely, with no electrical connections and zero power consumption. Additional Benefits … Read more A Closer Look: Crystalfontz ePaper 200×200 1.54″ Zero-Power Display
When working with a 20×4 character LCD, you might be surprised to see the controller set to 2-line mode: Write_To_LCD(COMMAND,0x38); //SET 2 LINE,5*8 FONT Why would a 4-line LCD’s controller be set to 2-line mode? It has to do with the way the LCD glass is laid out. Essentially the display is the right and … Read more FAQ: Why does the initialization code for a 20×4 LCD specify 2-line mode?
Confused about the differences between TFTs, LCDs, and OLEDs? What Do They Stand For? TFT stands for Thin Film Transistor (shorthand for “Active Matrix TFT LCD”) LCD stands for Liquid Crystal Display (shorthand for “Passive Matrix LCD) OLED stands for Organic Light Emitting Diode How Do They Work? TFT displays are also known as an “Active Matrix TFT LCD module” … Read more FAQ: What is the Difference Between a TFT, LCD, and OLED?
Here is a not-so-common customer question: Is it possible to measure server temperatures using 30 different sensors, 200 feet away from the computer? Answer: Yes, this possible! Our WRDOWY17 temperature sensor is a natural choice for this type of application. The Crystalfontz 16×2 character LCD with keypad gives an easy serial or USB interface to 32 WRDOWY17 sensors. … Read more Not So FAQ: Can you use 30 temperature sensors, 200 feet from the PC ?
Our tech support team is often asked for information about “how to code an LCD.” In other words, how do I get started (and what is the best choice) of an LCD module for my project? Answer: The Crystalfontz Advanced LCD Modules are the quickest and easiest way to power up and run your LCD. These … Read more FAQ: How Do I Code For A Crystalfontz 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 … Read more Tutorial: Driving a 144×32 Graphic LCD
Crystalfontz actively supports learning, especially for engineers-in-training. A few months ago, we were approached by a senior student working on a capstone project at EWU and the project was unveiled at a poster presentation on June 1st at the university. We are impressed by this project, incorporating a Crystalfontz 835 LCD module and an Arduino … Read more Engineering Project: Crystalfontz 835 and an Arduino Mega 2560
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 … Read more Engineering and Art
