LITRONIX - DL1414CE – Intelligent Alphanumeric 4 Digit Character LED Display, New.

LITRONIX - DL1414CE – Intelligent Alphanumeric 4 Digit Character LED Display, New. The Litronix DL1414CE is a 4-digit, 16-segment "intelligent" alphanumeric LED display module featuring an integrated CMOS circuit with a 7-bit ASCII decoder, character generator, and display RAM. This vintage component, also produced by Siemens and Hewlett Packard, is designed to be easily driven by microprocessors due to its built-in logic. Technical Specifications • Display Type: 4-digit, 16-segment “Intelligent” alphanumeric red LED with a "bubble" lens for magnification. • Character Height: Approximately 2.85mm (0.112 inches). • Interface: 7-bit ASCII data input with 2-digit address lines. • Voltage: Operates on a nominal 5V supply. • Package: 12-pin Dual In-line Package (DIP). • Material: Red GaAsP (Gallium Arsenide Phosphide) LEDs. • Made in USA Comparison to Related Models • DL1414 vs. DL2416: The DL1414 is a more compact version of the DL2416, lacking cursor generation and display blanking functions to reduce pin count and size. • DL1414T: This variant is functionally identical but often specifically cited for its readability at distances up to eight feet when used with proper filters. Interface: To interface the Litronix DL1414CE with an Arduino, you can use a direct parallel connection or shift registers to save pins. Because it has integrated CMOS logic, it does not require external resistors for the LED segments. • HPDL1414 by Marek Ledworowski (marecl): A simple, architecture-independent library that supports basic printing and text scrolling. • HPDL1414 by sumotoy: A high-performance library optimized for fast SPI operation (when using shift registers) and low memory footprint. • AceSegment: A broader library for rendering to various LED modules, though it may require more configuration than a dedicated DL1414 library Wiring Diagram (Direct Connection) • A direct connection requires 10 digital pins from your Arduino (7 for data, 2 for address, and 1 for write-enable). To reduce the pin count from 10 to just 3 wires (plus power), you can use two 74HC595 shift registers in series. Wiring Diagram (Direct Connection) A direct connection requires 10 digital pins from your Arduino (7 for data, 2 for address, and 1 for write-enable).
