实时系统编程学习－－ARM 指令集，各种指令分类详解

三星公司S3C2410开发板详细资料，PDF格式包含电路图供比较。

基于51单片机的数字电子钟调时+定时程序-Digital electron clock Fixed time

windows操作系统下的uploader-windows operating system under the uploader

可以实现年月日时分秒星期等的读取和写入，并使用串口形式以送到电脑上显示。可以适当修改就可移植到其它方面应用，比如结合LCD就可以显示。

Cortex ARM-M4 STM32F4XX使用的硬件模块CRC.计算CRC32带poly 0x04C11DB7（以太网）任意长度缓冲区。Keil 4的项目。

灰色PID的位置跟踪MATLAB源程序代码-PID

应用背景DHT11单片机驱动程序 包含两个时钟条件下的程序 ，这个设备对时钟要求非常高，好多朋友挑不出来主要是时间延迟没有做好，经过多次测试，本次给出的程序可用。关键技术 主要是把时间延迟那部分做好，写好时间延迟函数就好了，其他部分参考买设备的时候厂家给的代码，非常好用，厂家的技术支持很赞的。

嵌入式linux在arm开发板上的移植-Embedded linux development board in arm transplant! ! !

SMALL RTOS是为小ram系统单片机编写的,目前仅在51系列单片机上成功运行,还没有在其它单片机上移植(目前我仅有51和avr的开发系统).在小ram系统单片机如51系列上运行tcp/ip 协议栈是不太现实的.一般tcp/ip 协议栈需要在32位单片机上运行,在8位机上运行太勉强(51是8位机),除非您只运行ip协议.建议使用ucos/ii操作系统或是嵌入式linux,并选用arm或龙珠系列单片机-SMALL RTOS for small microcontrollers ram system, written in 51 series of microcontrollers currently only on the successful operation, no other MCU on the transplant (currently I am only 51 and avr development system). In the small ram System-on- machines such as the 51 series of films running on tcp/ip protocol stack is not very realistic. General tcp/ip protocol stack need to run 32-bit microcontrollers in the 8-bit machine running Taimian Jiang (51 is the 8-bit machine), unless you run only ip protocol is suggested. ucos/ii operating system or embedded linux, and use arm or Pearl Series MCU ..
