编码器DSP TMES320LF2407程序

arm7内核的verilog代码，可以综合，虽有几条指令没有实现，但已实现的功能对理解arm体系结构已足够-ARM7 core Verilog code can be integrated, although some commands do not realize, it has been achieved in understanding the functional architecture has enough arm

arm软件调试程序，可以代替jtag方针器对arm进行软调试，也可嵌到开发软件中。-arm software debugger, JTAG policy can substitute for the soft right arm debugging, but also to the development of embedded software.

开发三星arm9s3c2410代码，差不多包括其全部功能！-development code, including almost all of its functions.

一个用LP2148实现的MP3工程，包括FAT文件系统，采用SD卡-LP2148 realize a use of the MP3 works, including the FAT file system, the use of SD cards

本文UDP是根据我学习ARM开发以来的一些经验总结，以自己设计的S3C44B0X板为例，给出入门上手的最基础知识。有些东西只是个人的主观认为，不一定准确，算作抛砖引玉吧，欢迎大家指正！-This paper is based on UDP, I study the ARM since some experience to design its own board of S3C44B0X example, the entry is easily the most basic knowledge. Some things are just personal subjective view, is not necessarily accurate, it counted as something, we welcome correct!

应用背景姿态解算应用于飞行器、人体等载体的实时空间姿态的获取。能够重构载体姿态的空间位置。最常应用于飞行器，使飞行器能在空间保持平稳飞行。也包括可穿戴设备上的应用，能够估计人体步伐，进而进行空间定位。本资包含程序以及文档，非常详细的介绍了现有的几种姿态解算算法的原理。资源内包含的算法程序代码为原创代码，并不是网络上流传的MAK代码。关键技术算法核心用到了EKF扩展卡尔曼滤波，扩展卡尔曼滤波是公认的最优解滤波算法，它的收敛速度最快，在不同的应用中调整相应常数，既能达到良好的效果。资源中的EKF算法还属于比较粗糙的阶段，数据通过传感器采集后直接进入滤波器算法。如果要实际应用，必须对采集的数据先进行第一阶段的处理，再进入滤波器，否则扰动很大。另外资源也介绍了另外两只姿态求解算法，有需要请下载，相信该资源值得下载。

1.单机自发自收串行通信。接收键入字符，从8251A的发送端发送，与同一个8251A的接收端接收，然后在屏幕上显示出来。 2.双机串行通信，在一台PC机键入字符，从8251A的发送端发送给另一台PC机，另一台PC机的 8251A的接收端接收，然后在屏幕上显示出来。 -1. Since the resumption of spontaneous stand-alone serial communication. Type the characters receive from the sending end to send the 8251A, 8251A with the receiving end of a receiver, and then displayed on the screen. 2. Dual serial communication, in a PC-type characters, from the sending end 8251A sent to another PC, another PC-8251A to receive the receiving end, and then displayed on the screen.
