嵌入在 sim908 的调制解调器。在文件中你有 sim900 开发 IDE 和与普康吃使用 Eclipse IDE 的说明。 示例文件和编译器。 运行所需的 RVCT 编译器

步进电机接口

这是C8051F410比较器的源程序，对模块化编程很有好处。-This is a C8051F410 comparator source, is very beneficial for modular programming.

本文介绍了红外多路遥控系统。红外多路遥控系统可实现16路的红外开关控制。以码分制多通道红外遥控为设计的基本思路。通过键盘及代码生成电路、编码、脉冲调制振荡和红外发射构成红外发射电路。通过红外接收，解码以及由单片机控制的医码控制电路组成红外接收电路。-The passage has introduced the nfrared multichannel system of remote control. The infrared multichannel system of remote control can realize the infrared switch control of 16 roads. With yard divide into system the basic train of thought with much passageway infrared remote control of design. Through keyboard and code generation circuit, coding and pulse modulation vibration with infrared project to form infrared project circuit. Pass infrared take over , decode as well as the medical yard control circuit composition that controled by single flat machine are infrared to take over circuit.

Interface HT1621 to PIC16C5X

日历时钟模块，用于不带时钟芯片的系统-calendar clock module for the non-chip clock system

verilog写的回波抵消程序，相当于写了个回波抵消的芯片，不是dsp，可编译后下载于FPGA,绝对原创，写了很长时间。-Verilog echo canceller written procedures, wrote the equivalent of echo canceller chip, not dsp, can be downloaded from the compiled FPGA, absolute originality, writing for a long time.

用C语言模拟I2C时序功能，已经调试通过，可以直接使用-C language simulation with I2C timing functions, has been through the debugging, you can directly use

这是用ADS1.2实现的MINI2440启动的BOOTLOADER原码。我自己写的。-This is achieved using ADS1.2 source MINI2440 start BOOTLOADER. I wrote it myself.

按键输入1至9任意组和，使用数码管进行显示，另有6个功能键用做开始计数，停止，减数，主要需要熟练使用标志位即可树立理解此代码
