刚学ARM9 Linux LCD 开发的朋友，不妨试下这个例子，对你学习有帮助，测OK

lpc2131 IAP在线升级演示程序，升级方式为UART。-lpc2131 IAP-line demonstration program to upgrade, upgrade to UART.

在进入正题之前，我想先把ARM920T的异常向量表（Exception Vectors）做一个简短的介绍。-Before entering the subject, I would like to first abnormal ARM920T to Scale (Exception Vectors) do a brief description here.

基于ARM7的开发板的存储器重映射驱动程序，文件里有程序的详细注释，对与在此基础之上的二次开发非常方便-based on the ARM7 development board memory re-mapping driver, the documents detailed procedures Notes right and the basis of this second development is very convenient

我在使用陈明计先生写的small RTOS和51单片机做过几个小项目，起初都很好，开发变的容易了，程序变的容易修改。后来随着任务个数的增多，RAM很快就不够用了。51系列的芯片内部RAM普遍都是256个,很难找出1024个字节RAM或更多，而价格又合适的。记得上一次我没有办法被迫使用了64K flash内部带768字节的XRAM的51芯片，而我根本用不到那么多flash。-I use Mr. Chen Mingji written small RTOS and 51 MCU done several small projects at first were very good to develop easy to change the program become easier to modify. Subsequently, the increase in the number of tasks, RAM is not fast enough. 51 series of chip RAM are generally 256, it is difficult to find 1024 bytes of RAM or more, while prices will be appropriate. I remember the last time I had no way forced to use a 64K flash with 768 bytes of internal XRAM of 51 chips, and I will never use that much flash.

DSP2812的AD采集 采用的是中断的方式 用EV出发中断-DSP2812 s AD collect。it is interrupt ,use EV

经过大量测试，稳定可靠，可用于51单片机驱动SSD1305芯片控制的液晶屏。采用C语言模拟SPI接口，实现51与SSD1305通讯。

ARM7的UART驱动程序 可以自由配置缓存大小 驱动函数集 以及接口简单 很适合初学者提高自己的驱动开发能力的参考程序 产品级别的代码 注释很详尽 但需要自己提供IRQ部分的初始化部分程序 本作者不提供 程序为原创-ARM7-UART driver can configure the cache size of the drive free set of functions and simple interface is suitable for beginners to improve their ability to drive the development of reference procedures for product-level code is very detailed notes, but some need to provide their own IRQ initialization part of the process of this author does not provide procedures for the original

很好powerpc源码，从事汽车ecu开发的值得一看，本部分为etpu部分源码-A good source of powerpc
