网线测试仪程序，可测试网线长度（300M内），排序，用脉冲反波测试，时间*速度=距离的原理。-Cable tester program to test cable length (300M) with sorting, using anti-wave test pulse, time* speed = distance principle.

DAC1230是一个12位的模数转换的芯片!而使用时候是在8位的单片机上运行,所以需要注意高四位和低八位的写入时序-DAC1230 is a 12-bit analog-digital conversion chips! Use of time in the 8-bit single-chip run, so it is necessary to pay attention to the high four and low eight write timing

使用国产CH341A芯片实现USB转串口，完全兼容AVR JTAGICE，可以自动升级。 支持芯片: ATmega16(L), ATmega162(L), ATmega169(L or V), ATmega32(L), ATmega323(L), ATmega64(L), ATmega128(L). 原理图还附加了RS232接口，可以方便用户自主选择串口或USB下载程序。 还附加有可自动升级的HEX文件-The use of domestically produced CH341A chip USB to serial port, fully compatible with the AVR JTAGICE, can be automatically upgraded. Support chips: ATmega16 (L), ATmega162 (L), ATmega169 (L or V), ATmega32 (L), ATmega323 (L), ATmega64 (L), ATmega128 (L). Schematics also added a RS232 interface, can easily users to choose the serial or USB download. Additional there is also automatically upgrade the HEX file

本源码的目的是让大家熟悉单片机内部EEPROM的读写方法 -The purpose of this source is well-known single-chip internal EEPROM reading and writing methods

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.

压缩包里包括的５１的Ｃ与汇编的混合编程，并附有详细的稳当说明，想要深入了解混合编程责不要错过-Compression bag included in the compilation of 51 C with a mixture of programming, together with a detailed description of the sound, you want a deeper understanding of mixed programming Select Do not miss

利用PWM和移位运算设计，并利用人眼的视觉 暂留现象产生移动，并拖影的动态发光效果-Use of PWM and displacement computing design and the use of the human eye

中音音符dou，根据书上频率以及指令周期编写，时钟频率12m。比较easy。-tenor notes, books and instruction cycle frequency prepared, clocked 12m. Comparison easy.

ADS7843的应用。用来做触摸屏。是不错的东东。拿来可用-ADS7843 applications. Used to make touch screen. Is a good Dongdong. Use of available
