[Felipe Tavares] wasn’t satisfied with the boring default fonts on an HD44780-based display. And while you can play some clever tricks with user-defined characters, if you want to treat the …read more Continue reading Pixel Graphics From an HD44780, By Cutting Wires
As frustrating as it may be for a company to lock you into its ecosystem by encrypting their protocols, you have to admit that it presents an enticing challenge. Cracking …read more Continue reading Alarm Panel Hack Defeats Encryption By Ignoring It
There are too many different kinds of displays – some of them, you already know. I’d like to help you navigate the hobbyist-accessible display world – let’s take a journey …read more Continue reading Displays We Love Hacking: The HD44780 Family
If you’ve been pining for a retro-chic 16×2 LCD display to enhance your Windows computing experience, then [mircemk] has got you covered with their neat Windows-based LCD Info Panel. Your …read more Continue reading Arduino-Powered Info Display For Your Windows Computer
These days, there’s a huge variety of screens on the market for use with microcontrollers. OLEDs and graphic LCDs abound, while e-ink devices tempt the user with their clean look and low energy consumption. However, for many purposes, the humble …read more

While the SSD1306 OLED has somewhat become the go-to display for up-to-date projects, the good old character displays with their Hitachi HD44780 controller don’t seem to be disappearing just yet either. And why would they, especially if you want to show just text, having a built-in font has certainly its …read more
Most Hackaday readers are likely to be familiar with character LCDs driven by the extremely common Hitachi HD44780 controller chip. If you’re looking for a cheap and easy way for your microcontroller project to display some data, they’re pretty much the go-to solution. But as popular as these displays are, …read more
While most people are satisfied with a calculator application on their smartphone these days, there’s still something to be said for the old fashioned desk calculator. Maybe it’s the fact the batteries last long enough that you can’t remember the last time you changed them, or the feel of physical …read more

The venerable Commodore 64, is there anything it can’t do? Like many 1980s computer platforms, direct access to memory and peripherals makes hacking easy and fun. In particular, you’ll find serial & parallel ports are ripe for experimentation, but the Commodore has its expansion/cartridge port, too, and [Frank Buss] decided to hook it up to a two-line character LCD.
Using the expansion port for this duty is a little unconventional. Unlike the parallel port, the expansion port doesn’t have a stable output, as such. The port contains the data lines of the 6510 CPU and thus updates whenever RAM is …read more
