摘要
Abstract
Considering of the speed requirements of LED panel system while processing data,MCU impulse signal produces SCK signal,so as to drive the LED panel,and display data can moved into unit of the board in the group shift registe directly without passing CPU,which based on DMA thought.This paper introduces STC12C5616AD MCU（RD） and SPI interface＇s ＂DMA＂ mode in the application LED panel,highlighting the advantage of ＂DMA＂ mode in the LED large screen display system.关键词
