空孩子3310的程序，给需要的朋友－－－－－pcf8848-3310 children

由于原代码是编译89c51cc01的C代码，用于CAN总线

在89C51上实现TCPIP协议-89C51 in achieving agreement TCPIP

本设计以P89V51RD2FN单片机为电动小车的控制核心，采用MSA-LD2.0倾角传感器实时测量跷跷板的倾斜角，用ST198光电传感器检测黑色引导线监测小车运动。光电传感器和倾角传感器模块把实时测量信号馈送至单片机，利用专用细分芯片TA8435H驱动步进电机，以脉宽调制式斩波方式对步进电机步进角进行细分，控制和调节小车速度。采用增量式PID控制算法确保小车能够达到平衡；用RT128×64M液晶显示时间、角度等参数。经测试表明：小车各项性能指标达到设计要求，能够实现30秒内小车行驶到规定点，并保持跷跷板平衡；在跷跷板一端配重可调整的情况下，小车也能自动找到平衡点并保持跷跷板平衡。-The single-chip design for the electric car P89V51RD2FN control of the core, the MSA-LD2.0 seesaw angle sensor real-time measurement of the tilt angle, the detection of black ST198 photoelectric sensor to monitor vehicle movement and guide lines.Photoelectric sensors and angle sensors in real-time measurement module to feed the signal to the microcontroller, using a dedicated sub-chip stepper motor driver TA8435H to PWM chopper-type stepper motor on the sub-stepping angle, control and regulation vehicle speed. The use of incremental PID control algorithm to ensure that the car can achieve balance with LCD RT128 × 64M time, angle and other parameters.After the test showed that: the performance car

智能门禁系统采用凌阳十六位单片机作为系统控制核心，利用其强大的语音识别功能，不仅实现了语音播放功能，完成了语音提示的要求，而且实现了语音控制门禁系统；利用其内置的Flash闪存，实现了密码的断电保护。除此而外，在键盘输入方面，强大的功能选择键满足了系统的要求；16*2液晶显示器的选择使操作要求清晰明了。此套智能门禁系统强烈体现了其人性化的一面-Intelligent access control system uses the Sunplus 16 single-chip system control as the core, to use its powerful voice recognition features, not only realize the voice playback, the voice prompts to complete the requirements, but also realize the voice control of access control systems the use of its Purchase of Flash memory, realize the power to protect your password. Furthermore, in keyboard input, the choice of powerful features to meet key requirements of the system 16* 2 LCD display options so that operating requirements clear. This set of intelligent access control system strongly reflects its human side
