| Abstract: | To resolve the disadvantage of video control card for LED display screen not working well independently of PC, an off-line Control Card for Traffic Guiding Display is designed, in which ARM7 core chip S3C44B0X is used to accomplish 100M UDP network communication with PC, display-data storage and update; and with the assistant of FPGA, dynamic scanning and renovation of the screen are realized by method of couple RAM control. This system has been testified in practical application and fulfill good performance. |
