Design and practice of single-chip computer motion-picture styled LED displaying control system

This paper describes a cost-effective motion-picture styled LED displaying controlling system based on single-chip computer, including hardware structure equipped with a mother control board , a sub-control board and displaying driving circuits. Moreover, this paper also provides with a detailed software design flow-chart. A new generation of MCU is selected which is manufactured domestically. It is characteristics of high speed, low dissipation and super high anti-interference. It´s command system is compatible with 8051. Moreover, a SPI is chosen between the mother board and the SD card to make the communication even sampler and more efficient. In addition, the communication between the mother board and it´s sub-mother board is achieved by a Half-duplex styled 485.
