头件的中的#ifndef，这是一个很关键的东西。比如你有两个C文件，这两个C文件都include了同一个头文件。而编译时，这两个C文件要一同编译成一个可运行文件...

此软件是PIC单片机的编程助手软件，你可以通过它来设定一些内部模块的使用情况(如定时器，SCI，CCP)等模块的设置。省去了人工去记这些设定值。设置完成后可以自动生成C源程序。 -this software is the PIC microcontroller programming software assistant, You can set it to the internal use of the module (such as Timer, SCI, CCP) module configuration. Save a manual to remember these values. After the completion of installation can be automatically generated C source files.

51单片机通讯类软件。菜鸟级别。希望大家多多指点！-51 single-chip communications software. Rookie level. I hope everyone a lot of advice!

温控程序，利用PIC单片机产生PWM波形调整风扇转速，采用了PID算法，能较好的实现温控功能，温度能稳定在预设点，也可以由主机端串口实现温度设定，带Proteus仿真 ，对初学PIC单片机者有一定帮助-temperature controll system,controll signal is PWM generated by PIC MCU,the system work well,this program is helpfull for new designer off PIC MCU

本设计的由单片机控制的自动加料系统是与料斗式干燥机配套的加料系统。根据加料工艺要求，其工作原理是：先将真空管关闭，启动电机，用低真空气流将塑料树脂粒子送入真空管，电机停转，再将粒子排入料斗，如此循环。-The design of single-chip microcomputer controlled by the automatic feeding system with hopper dryer feed supporting system. Charging process in accordance with the requirements of its working principle is: first vacuum tube to close, start motor, using low vacuum plastic resin particles will flow into the vacuum tube, the electrical switch to stop, and then particles into the hopper, and so the cycle.
