目标：手工选择视频图像上的待跟踪目标；利用块匹配的方法估计目标区域在下一帧图像中的位置；循环这个过程直到目标从图像帧中消失。 技术：avi视频流的帧读取；图...

（1） 有一个主持人控制开关和8路抢答按扭，当主持人允许抢答时才能进行抢答操作，并用一个数码管显示抢答选手的号码，同时其他选手不能再抢答。 （2）电路上要加个蜂鸣器的电路，当有选手抢答时蜂鸣器响一下。 （3）要有倒计时功能，开始抢答时开始倒20秒计时，用两个数码管显示，当有人抢答时停止倒计时。 2.2拓展部分 用按键可设置倒计时的时间，范围在5秒到30秒之间。-(1) has a host switch and 8-way control button to answer in, when the moderator allowed to be carried out to answer in time to answer in operation, and use an LED display to answer in the number of players, while other players can no longer answer in his place. (2) the circuit, we should add a buzzer circuit, when there are players when the buzzer rang to answer in about. (3) to have the countdown feature to begin to answer in 20 seconds when you start down time, using two digital tube display, when someone stops to answer in the countdown. 2.2 The expansion of part of the buttons can be set with the countdown time, the range of 5 seconds to 30 seconds.

PWM控制电机,编辑控制方式。在这个DEMO里建了一个函数F_Pwm(int a,int b) 用于PWM设置，传入两个参数第一个用于频率设置，第二个用于占空比设置。另外还开了外部中断可进行频率和占空比的步进，从而达到调整速度的目的-PWM motor control, edit control mode. In this DEMO was built inside a function F_Pwm (int a, int b) for the PWM settings, with two arguments the first one for the frequency setting, the second set for the duty cycle. It also opened the external interrupt can be the stepping frequency and duty cycle to achieve the purpose of adjusting the speed of
