摘要

设计了基于电力线载波模块及单片机的LED点阵图文显示控制系统。该系统以基于STC7538芯片的电力线载波模块为显示信息传输工具

以STC12C5A60S2单片机为控制核心

以LED专用16位元恒流驱动器MBI5024为点阵列驱动控制

行地址经译码后通过中功率三极管控制点阵行驱动。LED点阵采用模块化设计

将高亮LED制成1616点阵模块

再由多个模块拼接成。

Abstract

LED dot-matrix display control system based on power line carrier has been designed. Power line carrier module based on STC7538 is used as the transmission tool of display information. Single chip microcomputer STC12C5A60S2 is used as control core. Dedicated LED 16 bit constant-current driver MBI5024 is used as dot-matrix control driver

in which raw address code is decoded and dot-matrix raw driver is controlled by the middle-power triode. LED dot-matrix is spliced by multiple 1616 dot-matrix modules

which is made by high light LED.
