STC89C52RC单片机 读取18B20数据并显示在数码管上(18B20 STC89C52RC microcontroller reads the data and displays on the digital)

利用单片机（STC89C52）为核心结合机械按键、数码管以及稳压器件等电子元器件组装了一个数字时钟，可以实现精准的计时以及修改等功能；(The combination of mechanical buttons, digital tube, and electronic regulator device the microcontroller (STC89C52) as the core components assembled a digital clock, and can achieve precise timing and modify functions )

在下的毕业设计，　　　本题要求设计一个直流电机控制系统。在设计中，采用国产单片机中目前比较新式的STC12C5A60S2作为整个控制系统的控制电路的核心，因为STC12C5A60S2内部有PCA模块，可以产生PWM波形；采用带中断的独立式键盘作为命令的输入，每当按键时蜂鸣器响；配以LCD12864显示实现对带光码盘的直流电动机转速参数的测量、显示和控制。LMD18200驱动模块内部是H型驱动电路，驱动能力较强，完成电机正反转以及速度的控制。为优化直流电机的响应，采用PID反馈，实现闭环控制。(Graduation in the next, and that the requirements to design a DC motor control system. In the design, the use of the relatively new domestic microcontroller as a control circuit of STC12C5A60S2 entire control system core, because STC12C5A60S2 internal PCA module can generate PWM waveforms using a separate keyboard with interrupt input as a command, whenever the button When the buzzer sounds accompanied LCD12864 display realize the measurement of the optical encoder with DC motor speed parameters, display and control. LMD18200 internal drive module is H-drive circuit, driving ability, and the speed of completion of the motor reversing control. In order to optimize the response of DC motor, using PID feedback, closed loop control.)

说明：  在51单片机上使用89C52的MPU，可以实现MPU6050采集数据，并且在1602上准确显示(Using 89C52 MPU on 51 single chip microcomputer, mpu6050 can collect data and display accurately on 1602)

改程序实现了以freescale的ms9s12x控制数字摄像头ov7670,及在两片5110上的显示。(Reform program implements to control the freescale ms9s12x digital camera ov7670, and the two on the 5110 display.)
