MAX7219用于键盘控制和led控制的专用芯片，对于初学者有很大的帮助。-MAX7219 uses in the keyboard control and the led control special-purpose chip, has the very big help regarding the beginner.

我老师为上课开发的单片机测试源程序，怎么可能“文件已存在”？-my teacher for the class of MCU development test program, how likely "file already exists?"

PWM波程序 可以用来控制电机调速，程序比较简单，这里只用了一个定时器就实现了。因为51单片机没有PWM波的寄存器，所以要自己用软件控制。-PWM waves program can be used to control motor speed, procedure is simple, here only a timer is realized. Because no PWM waves 51-series microcomputer to yourself, so with registers control software.

学习用，使用前，认真阅读，按实际情况更改IO口！-to study, use, read carefully, according to the actual situation changes IO mouth!
