Description: 实验箱的蜂鸣器是交流蜂鸣器，在BZSP输入一定频率的脉冲时，蜂鸣器蜂鸣，改变输入频率可以改变蜂鸣器的响声。因此可以利用一个PWM来控制BZSP，通过改变PWM的频率来得到不同的声响，以此来播放音乐。-Experiment Box AC buzzer buzzer is in BZSP certain frequency pulse input, the buzzer beeps to change the input frequency can change the sound of the buzzer. So you can use a PWM to control BZSP, by changing the PWM frequency to get different sounds in order to play music.

Description: 车牌识别系统一般包括车牌定位、车牌切分、字符识别三部分，而车牌定位是车牌识别系统的基础和前提，其准确与否直接影响着车牌识别的准确率。本文针对这一关键问题进行了研究，提取了车牌的颜色特征并结合其纹理特征、几何特征以及投影特征进行准确定位。采用HSV颜色模型，利用颜色空间距离相似度计算分割颜色；针对颜色分割后的图像，车牌区域内水平方向上具有的连续跳变的特征，采用行扫描法确定车牌的上下边界；车牌区域内垂直方向具有投影特征，采用垂直投影法确定车牌的左右边界；最后根据车牌的宽高比判断是否是真实的车牌域。实验结果表明该方法效果较好、精度较高。-License plate recognition system generally includes license plate location, license plate segmentation and character recognition. And vehicle license plate location is a key stage of license plate recognition system, whose accuracy directly affects license plate recognition system’s performance. This paper studied the key issue, which mainly used color feature combining the texture feature, geometric feature to obtain accurately positioning. The HSV color space and similarity calculation was used to segmented image. Because the vehicle license plate have this property of consecutive beeps in horizontal direction, and line scanning method was used to determine the top and the bottom boundary of vehicle license plate. And also the vertical projection was used to determine the left and right boundary of the vehicle license plate because of its projection property in vertical direction. Finally, according to the HVR to judge whether the area is true. Experimental results showed that the al

Description: VHDL语言实现多功能数字钟设计：(1) 计时功能：这是本计时器设计的基本功能，每隔一分钟计时一次，并在显示屏上显示当前时间。
(2) 闹钟功能：如果当前时间与设置的闹钟时间相同，则扬声器发出蜂鸣声。
(3) 设置新的计时器时间：用户用数字键‘0’～‘9’输入新的时间，然后按 "TIME"键确认。
(4) 设置新的闹钟时间：用户用数字键“0”～“9”输入新的时间，然后按“ALARM”键确认。过程与(3)类似。
(5) 显示所设置的闹钟时间：在正常计时显示状态下，用户直接按下“ALARM”键，则已设置的闹钟时间将显示在显示屏上。
-The multi-function digital clock VHDL language design: (1) timing function: This is the basic functions of the design of the timer tick once every one minute, and the current time displayed on the screen.
(2) Alarm function: If the current time and set the alarm time, the speaker beeps.
(3) set a new timer time: use the number keys 0 to 9 to enter a new time, and then press the "TIME" button to confirm.
(4) set a new alarm time: the user to enter a new time, using the number keys "0" to "9" and then press the "ALARM" button to confirm. The process is similar to (3).
(5) set the alarm time: the normal time display, the user directly pressing the "ALARM" key already set the alarm time will be displayed on the screen.

Description: 当触动开关时，内部扬声器发出间断的蜂鸣声，并且4个LED指示灯循环闪烁。一段时间后，LED指示灯熄灭，蜂鸣声停止。随后LED显示屏开始从9到0倒计时，若在倒计时的过程中，再次触动开关，就会发出所设计的第二种警报：内部扬声器发出持续蜂鸣声，并且4个LED指示灯共同忽明忽暗闪烁。同样持续一段时间后，LED指示灯熄灭，蜂鸣声停止。-When a switch, the internal speaker intermittent beeps, flashes and four LED lights cycle. After a certain period of time, the LED light is off, the beep stopped. Then the LED display countdown from 9 to 0 in the countdown process, once again touched the switch, we will send the second warning design: internal speakers emit a continuous beep, and four LED indicators together convulsively flashes flickered. Also continue for some time, the LED light is off, the beep stopped.

If the code is entered in the correct sequence, then after 1 second
the relay and the electric striker (in the door) switch on for 1
second and then switch off again.
User code can be changed via 3x4 matrix keypad. Keypad can be
bought at local electronic shop.
Initial user code (1234) is set up with a jumper. The jumper must
be inserted before the voltage (12V) connection. The jumper must

Description: BEEPS图像过滤算法源代码The smoothing is applied by the way of a bi-exponential filter, itself realized by a pair of one-tap recursions. It is therefore very fast; moreover, its computational cost is truly independent of the amount of smoothing. Meanwhile, the preservation of edges is obtained by a range filter akin to the range filter found in a bilateral filter。
