14班05号朱韬单片机设计实验报告 2011年小学期单片机设计实验报告 题目：基于PIC16F877的遥控小车 班 级： 2009211116班 小班学号： 05 实验组号： 23 学生姓名： 朱韬 指导教师： 张老师 葛老师 周老师 期中检查  教师评语 指导教师签字： 年 月 日 基于16F877的无线小车遥控系统 ――16班 朱韬 实验摘要 这次小学期我们制作了基于16F877的无线小车遥控系统，这辆小车可以在遥控器的控制下，可以实现小车的60%速度前行，80%速度前行，100%速度前行，左转，右转，后退共六个功能。 遥控功能，解码编码芯片分别采用PT2272,PT2262，无线收发芯片采用F05V，J04V，采用这些芯片的原因是收发信号稳定，遥控距离远。但缺点也是显而易见的，无线模块的调节对于初学者来说稍显困难。 电机驱动采用L298N，性能稳定，但发热量较大。 整个系统中，微控制器采用了Microchip公司的PIC16F877，软件设计中PORTB1-4为输入端口PORTC4-7为输出端口，PORTB0为中断开端，PORTC端口的CCP模块的PWM脉宽调制输出功能。 整个系统功能的实现，通过PT2262外接按键，产生高低电平，通过F05V无线发射，J04V接收，PT2272进行解码将数据传送给单片机16F877,16F877的输出端控制电机驱动芯片L298工作，整个小车的工作系统如上，过程简单，但实现起来在硬件调试上颇有难度。 Abstract This semester we have produced a car based on 16F877 wireless remote control system, this car car can be under the control of the remote control, can achieve 60% of the speed the car forward, forward rate of 80%, 100% speed forward, turn left, turn right, back a total of six functions. ???Remote control function, encode and decode chips were used PT2272, PT2262, wireless transceiver chip F05V, J04V, because using these chips send and receive signal stability, remote distance. But the disadvantage is obvious, the regulation of the wireless module is somewhat difficult for beginners. ???Motor drive using L298N, stable performance, but the larger heat. ???The entire system, the microcontroller uses Microchips PIC16F877, software design PORTB1-4 for the input port PORTC4-7 for the output port, PORTB0 beginning to break, PORTC port CCP module for PWM pulse width modulation output. ???The realization of the entire system functions through PT2262 external buttons, resulting in high and low, through F05V wireless transmitter, J04V receiver, PT2272 to decode the data transmitted to the microcontroller 16F877, 16F877 output of the L298 motor driver chip controls the work of the whole car system w
