RS232串口通讯模块

用户名admin、密码123456可登录到管理员级别的用户界面。 用户名user、密码123456可登录到普通用户级别的用户界面 初始的家庭成员财务信息文件名为family，如要利用此系统进行家庭成员财务信息的管理，系统会提示用户输入家庭成员财务信息的文件名，则要输入此文件名，或输入管理员使用系统时新建的文件名。如删除该文件，则需在系统中调用相应的功能函数重新创建初始化文件。 初始的用户信息所在的文件名为yonghu，系统默认即为此文件名，不可删除。 -Username admin, password 123456 can log on to the administrator-level user interface. User name user, password 123456 can log on to the ordinary user-level user interface the initial members of the family financial information document, entitled family, such as to make use of this system of family members of the management of financial information, the system prompts the user to enter financial information of family members file name, will have to enter this file name, or enter the system administrator to use the new file name. Such as delete the file, then call in the system function corresponding to re-create the initialization file. User information where the initial document yonghu, that is, to this end the system default file name, can not delete.

很好的讲解java的ppt,很详细,不错-good java on the ppt, in great detail, yes

c++完美演绎源代码-c perfect interpretation of the source code

This book has been written with a broad spectrum of readers in mind, which includes anyone interested in secrecy and related issues.

控制信号由接收机的通道进入信号调制芯片，获得直流偏置电压。它内部有一个基准电路，产生周期为20ms，宽度为1.5ms的基准信号，将获得的直流偏置电压与电位器的电压比较，获得电压差输出。最后，电压差的正负输出到电机驱动芯片决定电机的正反转。当电机转速一定时，通过级联减速齿轮带动电位器旋转，使得电压差为0，电机停止转动。当然我们可以不用去了解它的具体工作原理，知道它的控制原理就够了。就象我们使用晶体管一样，知道可以拿它来做开关管或放大管就行了，至于管内的电子具体怎么流动是可以完全不用去考虑的。-Control signal from the receiver into the signal modulation of the channel chip, access to the DC bias voltage. It has a base internal circuit, resulting in a period of 20ms, the base width of 1.5ms signal, will be the DC bias voltage and the voltage comparator potentiometer to obtain the output voltage difference. Finally, the positive and negative output voltage difference to the motor driver chip motor positive decision. When the motor speed must, through the reduction gear drive cascading rotary potentiometers, the voltage difference is 0, motor to stop rotating. Of course, we do not have to understand the principle of its work, the control principle to know its enough. As we use the same transistors that can switch it to do or to enlarge
