这篇文档就是记录了我在前段时间学习、调试目前最低价的 ARM 核处理器——AT91SAM7Sxx 时出

现的问题与解决方法。它尽量完整地记录了我从开始不懂ARM，到最终完成AT91SAM7S64各种外围实验

的各个环节及整个过程，包括我在开始一个实验前的一些想法，实验目的，以及各个实验中，我以单片机

的思维去思考时遇到的各种问题，和这些问题的解决方法。现将自己的一点经验以及体会拿出来与大家共

同分享，一来是希望能够为那些在 ARM 门口徘徊迷茫的人提供一些借鉴，使他们顺利越过这道门槛；二

来是希望能够抛砖引玉，以结识更多有共同爱好的朋友。由于我也是新手上路，文章中难免疏漏与错误，

希望大家不吝指正，如果在调试AT91SAM7Sxx时有什么问题，欢迎大家共同讨论。 -This document is recorded in my earlier study, the lowest ARM debug the current core processor- AT91SAM7Sxx when the

Current problems and solutions. It is recorded as complete as possible from the start I do not know ARM, to the final completion of all external experimental AT91SAM7S64

All aspects and the entire process, including before I started an experiment some of the ideas, experimental purposes, and various experiments, I MCU

Mind to think about the problems encountered, and solutions to these problems. Now my little experience, and experience with you were out

The same share, the one who is to be able to hover in front of the lost ARM to provide some reference, so that they successfully crossed this threshold　II

To initiate the hope to make more friends with common interests. Since I am also a novice on the road, the article inevitably omissions and errors,

Hope that we hesitate to correct me, if you have any problems when debugging AT91SAM7Sxx, welcome to discuss.
