WUSB的运行采用MBOA–MAC架构，同时保留了主从架构，和USB 2.0一样，它也能处理控制、突发、中断和同步（Control、Bulk、Interrupt and Isochronous）所有这四种传输形式。主机和WUSB设备合称WUSB丛集，采用星型拓扑；与USB 2.0. A的树型拓扑不同，WUSB主机能直接连接多达127个设备，因此在WUSB丛集中不需要包含WUSB集线器 ...

The aim of this application note is to show to scan the 4x4 matrix keypad multiplexed with a four 7-segment display. The software attached to this application note scans the pressed key and displays it on the multiplexed 7- segment LEDs. This application note makes obvious Interrupt capability of ...
