The bleeding edge of ‘80s displays? Show smooth-scrolling text on a standard HD44780 character LCD with your Arduino.
Displaying smooth-scrolling text on old character LCDs
The bleeding edge of ‘80s displays?
July 12, 2020
https://joeraut.com/posts/smooth-scrolling-text-on-character-lcds/
Character LCDs have been around for a long time. These displays contain a number of discinct blocks—each capable of displaying a single character—so displaying scrolling text would traditionally involve just shifting characters left one block at a time. That’s fine and all, but why not take advantage of free time during quarantine to raise the bar..
Most character displays utilise the Hitachi HD44780 controller chip, which has the neat feature of letting us define and use up to eight custom characters, each 5×8 pixels in size. Mine uses this chip, so I’ll be taking advantage of repeatedly rendering custom characters to pull off smooth scrolling text.
I connected an Arduino Leonardo to my salvaged display over its 4-bit interface, and got to work on the software side.
As we use an Arduino, the software written is in C++. Source code available at the end of the article.
In order to display our canvas on the LCD, we define a function to generate display-ready custom characters by grabbing pixel data from appropriate locations on the canvas. For each frame of the scrolling process, we can simply increment the horizontal index of the location on the canvas by one, which results in the message on-screen scrolling left by one pixel. These custom characters are then pushed to the display, and presto—smooth-scrolling text!

wanted a simple battery-powered ‘scope for audio type applications. The ones I found on the Arduino website were not quite what I wanted and were not up to my requirements. I had the 3.5″ touchscreen which I bought from Amazon, and used that. The Arduino analogue sampling was too slow so I bypassed it and used direct control. I added timebase speed, input gain, trigger level and polarity and delay, and vertical shift facilities. All in one source file with the MCUfriend touch control software put in the same project folder.

Designed around a newly-released library for the Arduino IDE, Adafruit Industries’ guide could be the precursor to on-device computer vision projects.
Adafruit’s New Guide Showcases Live Video, Image Capture from an OV7670 Camera on SAM D51 Boards
https://www.hackster.io/news/adafruit-s-new-guide-showcases-live-video-image-capture-from-an-ov7670-camera-on-sam-d51-boards-8394e2ebd03f
Designed around a newly-released library for the Arduino IDE, Adafruit’s guide could be the precursor to on-device computer vision projects.
Adafruit has published a guide to using a low-cost OmniVision OV7670 camera module with the Grand Central and other SAM D51-based development boards — including how to get full-motion video running.
“OmniVision’s OV7670 is a small and inexpensive camera module occasionally seen in maker projects,” Adafruit’s Phillip Burgess writes. “In the past, with the limited RAM and speed of the Arduino Uno, this tended to be for small stills, transferred over USB to a computer for further processing.”
“Technology marches on, and the SAM D51 chip on Adafruit Grand Central and other M4 boards has a feature specifically designed with these cameras in mind. Along with a new Adafruit library, it’s possible to get full motion video out of the camera and to a display…with most of the CPU still available for other tasks.
