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.
