HDLU-2416中文资料Four Character 5.0 mm (0.2 inch) Smart 5 x 7 Alphanumeric Displays数据手册Broadcom规格书

描述 Description

This is a 5.0 mm (0.2 inch) four character 5 x 7 dot matrix display driven by an on-board CMOS IC. This display is pin for pin compatible with the HPDL-2416. The IC stores and decodes 7 bit ASCII data and displays it using a 5 x 7 font. Multiplexing circuitry, and drivers are also part of the IC. The IC has fast setup and hold times which makes it easy to interface to a microprocessor. The address and data inputs can be directly connected to the microprocessor address and data buses. The HDLU-2416 has several enhancements over the HPDL -2416. These features include an expanded character set, internal 8 level dimming control, external dimming capability, and individual digit blanking. Finally, the extended functions can be disabled which allows the HDLU-2416 to operate exactly like an HPDL-2416 by disabling all of the enhancements except the expanded character set. The difference between the sunlight viewable HDLS-2416 and the low power HDLU-2416 occurs at power-on or at the default brightness level. Following power up, the HDLU-2416 operates at the 27% brightness level. Power on sets the internal brightness control (bits 3-5) in the control register to binary code (000). The HDLU-2416 binary code (000) corresponds to a 27% brightness level. The other seven brightness levels are identical for both parts.

简介

HDLU-2416属于光电器件的显示器模块-LED点阵群集。由制造生产的HDLU-2416显示器模块 - LED 点阵和群集显示器模块 - LED 点阵和群集装置是使用布局成矩阵形式的发光二极管来提供可视图形的器件。它们通常以网格状排列，发光二极管的正或负端子连接在一起作为公共电路节点。这些装置具有各种尺寸和颜色，并且可以接受各种接口，包括 I2C、8 位并行、串行和 ASCII 输入。
