PPP协议C语言源代码，可移植到嵌入式系统上！-It is the C source file of ppp protocol that can be transplanted to embeded systems.

串口复用协议GSM07.07相关源码，在软件上实现两个串口而实际只有一个物理串口；-Serial multiplexing GSM07.07 agreement related source in the software and the actual realization of the two serial ports that there is only one physical serial port

44b0的BOOTLOAD微机通讯程序，很实用--BOOTLOAD pc communication program of 44b0.

应用背景可以作为verilog初学者的计数器参考实验，本代码通俗易懂，且都有注释，不难理解。关键技术四位的FPGA计数器实验，四位二进制计数，最大数值记到15后清零。

这是mini2440开发板的裸机程序，可以用于蜂鸣器、AD转换、RTC时钟、按键测试、触摸屏测试、LCD或VGA测试、I2C测试、音频输出测试、SD卡测试等。代码编写很规范，注解到位，初学者可以慢慢从这些源代码学起。

红外遥控器已被广泛使用在各种类型的家电产品上，它的出现给使用家器提供了很多的便利。红外遥控系统一般由红外发射装置和红外接受设备两大部分组成。红外发射装置又可由键盘电路、红外编码芯片、电源和红外发射电路组成。红外接收设备可由红外接收电路、红外解码芯片、电源和应用电路组成。通常为了使信号能更好的被传输发送端将基带二进制信号调制为脉冲串信号，通过红外发射管发射。本设计采用Atmega8作为红外发射编码和接收解码芯片。-Infrared remote control has been widely used in various types of household electrical appliances, it" s there to provide the users a lot of convenience. Infrared remote control system in general by the infrared emission devices and infrared devices to accept the composition of two major parts. Infrared emission circuit device can be by keyboard, infrared encoder chip, power and infrared emission circuit. By the infrared receiver infrared receiver circuit equipment, infrared decoder chip, power supply and application circuit. Usually better in order to signal the sending end of the transmission to binary base-band signal for pulse modulation, through the launch tube infrared emission. The design uses infrared emission Atmega8 as encoding and decoding chip receiver.
