The Design And Implementation Of Control System For LED Graphic Display

LED graphic display as a high-tech product has attracted people’s much attention.At present, the central processing unit of most LED display controller is8-bit or16-bitmicroprocessor. There are a lot of limitations in computing speed, storage capacity andcommunication capabilities. Aiming at the above problems, the paper designs a kind ofgraphic display control system which is of large storage capacity, high processing speedand real-time cluster control through the network.The graphic display control system is based on the32-bit processorSTM32F103VET6in ST Company. By analyzing the hardware resource requirementsof the system, it completes the design of the main chip, Ethernet communicationinterface, JTAG, FLASH memory, and interface circuit of display driver, and it mainlycompletes the functions of display data processing and LED displays driving.Developed a web-based cluster control of the PC control software, it can complete theprogram editor, parameter configuration, remote cluster control and other functions.System debug show that this graphic display control system can realize the remotecluster control, it can complete the communication, information display, control andmanagement functions.
