Arch Model

说明：  51单片机使用printf输出调试信息，经测试完全可用，加入到自己工程，打开串口调试助手直接能显示内容，串口驱动部分借鉴宋老师手把手教学内容(51 Single Chip Microcomputer Prints Debugging Information with Princtf)

介绍如何在StrongArm下编写shellcode的知识。一开始先介绍了StrongArm的体系结构和指令集，后面给出了几个shellcode的实例。这些实例在HP iPAQ上的Debian Linux上开发，但原理可通用于StrongArm下的其他机型和其他linux版本。(This guide describes how to write shellcode in StrongArm architecture. At first it introduced the StrongArm architecture and instruction set, then it given a few examples of shellcode. The examples developed on HP iPAQ running Debian Linux, but the principle may be applicable to other models and other linux deployment.)

硬件平台：STM32F401板子 软件平台：Keil5 功能：实现不同占空比的PWM波输出，通过按键切换输出模式（25%，50%，75%三种占空比模式）同时外接数码管显示当前模式（1，2，3）(Hardware platform: STM32F401 board Software platform: Keil5 Function: realize PWM wave output with different duty ratio, switch output mode by key button (25%, 50%, 75% three duty ratio mode) and display current mode (1, 2, 3).)
