x5045的相关程序，可以在keil c 上运行-X5045 procedures, you can run keil c

本程序是PIC单片机自带AD转换功能的使用例子，并且采用了多次采样取平均值的方法进行抗干扰。-This procedure is a single-chip microcomputer PIC own use of AD conversion examples, and using a number of sampling methods to obtain the average interference.

本文详细系统地介绍了uC/OS-II 在51 单片机上的移植、重入实现方法、硬件仿真、固化、人机界面等关键内容。-paper detailed and systematic introduction of the Phone/OS-II in 51 MCU transplant and re-entry method, hardware simulation, curing, the man-machine interface and other key elements.

介绍了ATMEGA128的AD使用，很详细，值得一砍，不过是E文的-ATMEGA128 introduced the use of the AD, in great detail, it is worth a cut, but the text is E.

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
