摘要
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 16×16 dot-matrix modules, which is made by high light LED.关键词
