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。而由于WUSB没有缆线,因此,所有的WUSB设备都必须自行供电(self-powered)。

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 the STR710 device to offer a better key scan .

A one-dimensional calibration object consists of three or more collinear points with known relative positions. It is generally believed that a camera can be calibrated only when a 1D calibration object is in planar motion or rotates around a ¯ xed point. In this paper, it is proved that when a multi-camera is observing a 1D object undergoing general rigid motions synchronously, the camera set can be linearly calibrated. A linear algorithm for the camera set calibration is proposed,and then the linear estimation is further re¯ ned using the maximum likelihood criteria. The simulated and real image experiments show that the proposed algorithm is valid and robust.

UCOS/II for ICCAVR - The version of UCOS/II is 2.04 - the original port was done by Ole Saether for the IAR compiler. Jens E. Holtegaard ported one version using ICCAVR. Joerg Meyer did another port (using Jens port as a start?). This is basically Joerg s port plus a little bit of changes and documentation by me. - YOU MUST DOWNLOAD THE MAIN PART OF THE UCOS/II FROM THE UCOS/II WEBSITE http://www.ucos-ii.com . The supplied project file assumes the portable source is in the ..\source directory. - Joerg has written couple document showing the stack frames etc. but it is in German :-) They are included in this directory. - The Timer2 overflow interrupt is used for Timer Tick. If you want to change that, modify os_cpu_c.c and os_cpu_a.s - I have tested this using ATMega103 with and without external RAM using AVR Studio simulator. See test1.c test program. Both Code Compressed (PRO) and STD versions have been tested.
