LCD Connections & More

Small alphanumeric LCD displays are applied in many electronic circuits, particularly when microcontroller-driven. These displays are easy to control and not expensive. However, you will always need to know their connection details and other salient features. Fortunately the Internet abounds with technical information on LCDs, as well as interesting application briefs.When designing a microcontroller system, a terminal or any other intelligent circuit that needs to ‘show’ us something, an alphanumeric LCD is often the easiest way to obtain a readout device. A good choice, really, because LCDs are affordable, they offer a clear readout and are relatively easy to drive in software and hardware.
