The PCA2117 is a low-power Liquid Crystal Display (LCD) controller and driver. It is specifically designed to drive LCD dot-matrix displays of 2‑lines by 20 characters or 1‑line by 40 characters with ...

A small LCD screen can be extremely helpful with small microcontroller projects. Not everything needs to communicate to a fancy server using an ESP8266. However, if the simplicity of the character ...

Here’s an external display meant to help you keep track of your computer’s status. It connects via USB and is driven by a PIC microcontroller. It listens for a small set of commands, using those to ...

This project illustrates how the HD44780 LCD displays are driven by DIP switches or an ATmega8 microcontroller. This project illustrates how the HD44780 LCD displays are driven by DIP switches or an ...

Most LCD character displays connect to the outside world via a controller IC, such as the HD44780 (Hitachi) or equivalent. However, that interface has serious drawbacks. It uses a large number of the ...
