同学自己做的可调整计时器，大家看看！还有各种报告细节哦...

AVR mage8单片机的bootload程序、完整版本、本人做项目一下在用、此程序为13.56m晶振版本、非常好用-MCU AVR mage8 Bootload procedures, full version, I do projects about the use of, this procedure 13.56M crystal version, very easy to use

51的4*4键盘驱动当按键按下时返回一个值，且只在按下键时返回一次该值，之后返回0；无按键时返回0；包含消抖功能，在键盘的下降沿触发。 基于keil平台-51 4* 4 keyboard driver when the button is depressed to return a value, and press the button only once the value to return, followed by return 0 no keys to return 0 contains extinction Buffeting function, the falling edge trigger at the keyboard. Keil-based platform

RTC8563时钟芯片的读写程序，大家共享。

51汇编语言，格式为.chm文件，这个好象就是九十年代初孙涵芳（如果我没记错的话）写的一 本书后附的子程序。子程序不全对，至少有个除法的余数有问题，扩大了2倍，我记不清是哪个了，你把其中的一个左移语句去掉就行了，别的记不得了。欢迎常联系。-51 assembly language format. Chm documentation, It was like the early 1990s-wu (if I remember correctly so) wrote a book attached to the subroutine. Subroutine incomplete right, at least a division of the remaining problems, and expanded two times, I can not remember clearly what is, you put one of these bits removed statement on the visit, other reporters unnerving. Welcome regular contact.
