以S3C2410为目标板，利用串口读取读卡器的磁卡信息来控制LED的闪烁，用QT做的显示界面，模拟门禁控制,S3C2410 for the target board to the use of serial magnetic card reader to read the information to control the blinking LED, QT to do with the display interface, simulation of access control

实现多通到的视频监控，可通过qt界面跳转各个通道(Multi-access video surveillance can be realized by jumping channels through QT interface)
