PIC16F877实现按键扫描和数码管显示、蜂鸣片同时DD响，当按键下时，数码管加一，蜂鸣片DD响两次。-PIC16F877 to achieve key-scan and digital tube display, beep sound piece at the same time DD, when the button when you are not, the digital control plus one, beep piece DD ring twice.

To learn how to use MPLAB Integrated Development Environment (IDE) for code generation, simulation, and debugging. This code is a very simple program that sets up PORTC and PORTB I/Os and sends some values over these ports, and tries to read Port C and increments a counter and resets to a predetermined value when the counter rolls over to zero. All labels start in the first column, and the last line has an end directive. For detailed information, refer to the PIC18F452 datasheet on the course web page.

实现9层电梯控制 功能如下：1，先假设没上楼之前，楼层运行看不到(没图形），可以当做随机看待。 2。当在某层按电梯开关后，在屏幕显示电梯停到该指定楼层的图形状态。 3。随后可以按想去的楼层，在屏幕显示电梯运动过程，， 4，可选择是否还执行本程序（坐电梯）-9 realize elevator control layer functions as follows: 1, first assume that no public housing, before running the floor can not see (no graphics) can be viewed as random. 2. When a layer switch by the elevator, the elevator stopped on the screen display to the graphics state designated floors. 3. Then may want to go to the floor, in the screen display elevator movement process, 4, can choose whether the implementation of this program (elevator)

随着多样化需求的增加及作用距离的延伸，基带窄脉冲方式的超宽带技术又在原有的数据业务的基础上的到了提伸，IEEE802.15.4a就是一种采用基带窄脉冲方式的超宽带综合业务的标准-With the diversification and the role of increased demand from the extension of a narrow base-band pulse of ultra-wideband technology in the existing data services based on the mentioned stretch, IEEE802.15.4a is a base-band using a narrow pulse of Ultra-wideband integrated services standards
