摘要
文章介绍了基于MSP430单片机的低功耗LED点阵汉字显示屏的设计。本设计采用MSP430F249作为主控芯片,74HC系列154和595芯片构成行列驱动电路,4个16×16LED点阵级联构成16×64点阵显示器。该设计能够实现LED点阵显示器的汉字滚动循环显示,具有设计简单、显示清晰、超低功耗等特点。
This paper introduces the design of low power consumption LED dot matrix Chinese character display based on MSP430 single chip microcomputer. The design uses MSP430 F249 as the master chip, 74 HC Series 154 and 595 chips constitute the ranks of the driver circuit, four 16×16 LED dot matrix cascade to form a 16×64 dot matrix display. The design can realize LED dot matrix display Chinese characters rolling cycle display, with a simple design, display clear, ultra-low power consumption and so on.
