通讯规则: 1:时钟7.3728 MHz/波特率9600/9个数据位/奇校验/1个停止位/硬件多机通讯功能/ 2:通讯连接采用硬件MAX485,双向单工 (Communication rules: 1: clock 7.3728 MHz/9600 baud/8 data bits/odd parity/1 stop bit/hardware, multi-machine communication/2: Communication connection using hardware MAX485, two-way simplex)

无线通信的绕射损耗、反射损耗以及基站天线设计、不规则地形影响的课程教案(WIRELESS DECAY FOR reflect and base antan design )

Obj tracker for detection. Choosing a set of pixels using the square to complete what is called the object marking and lets you know of the pixels there

说明：  单片机上电以后LCD屏上显示欢迎回家， 先验证指纹再验证密码 ，同时验证成功开锁 指纹和密码分别可以验证3次 3次都错蜂鸣器响 ，按下manage键进入管理员模式 可以修改密码 删减指纹，指纹用开关量表示(After the microcontroller is powered on, the LCD screen shows welcome home. First verify the fingerprint and then verify the password. At the same time, verify the successful unlocking fingerprint and password can verify that the buzzer rings three times and three times respectively. Press the management key to enter the administrator mode to modify the password and delete the fingerprint. The fingerprint is expressed by the switch.)
