The CFA735 and CFA835 product lines have the option to store images on the display. Image from Computer. Open the photo in Paint I am going to just use a simple TESTING text in paint to demonstrate how to convert and show on your display. Sending the Photo to the Display Viewing the Photo on […]

Want to run custom firmware on a CFA735 or CFA835? You’re in luck! This tutorial will help you hack a CFA735/CFA835.

We recently had a forum customer ask for instructions on talking to our new CFA835. One of our excellent firmware designers, Mark, put together some sample code in order to do just that. I’ve created a project on GitHub to host this project Linked Here. We welcome comments, forks, and pull requests. Here’s a convenient […]

ATX stands for Advanced Technology eXtended and refers to a specification for motherboard and power supply configuration introduced in 1995. ATX remains the most common motherboard configuration, though different form factors have since been introduced. When “ATX” is used at Crystalfontz, it indicates that the module is configured to control the ATX power supply of […]

Confused about the differences between TFTs, LCDs, and OLEDs? What Do They Stand For? How Do They Work? TFT displays are also known as an “Active Matrix TFT LCD module” and have an array of thin film transistors fabricated on the glass that makes the LCD. There is one of these transistors for each pixel on the […]

Question from our tech forum: I’m looking to put LCDs on my new servers, which are pretty significantly complex even before you get into the software on them. This customer had a complex set of requirements for LCDs to be used in a server set up. Summary: Need to drive four LEDs, and need 14 […]

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 […]

Question: How do I display an image on CFA835 module using the RS232 interface? Answer:  You can send an image directly from your host application, or read it off the uSD card. Image Requirements for Use on an LCD Module The image needs to be a BMP, grayscale, 8 bits/pixel, no compression, Microsoft Windows format only. […]
