对于协议SPI ATmega示例代码

sprintf源码。独立一个文件就可用。在嵌入式等系统中可能用到。网上找了很多，多数都不能用或功能不全。这个是本人下了一翻功夫完善过的代码。-sprintf source. Separate a file can be used. In the embedded and other systems may be used. The Internet is a lot, most are not usable or insufficiency. This is the effort I made a frightening sound off code.

HM701NEP(S3C44B0X)基本启动代码,在此基础上可以做各种实验,包括个6文件,44BINIT.S 汇编代码，系统上电、复位及异常处理的入口点。 Memcfg.s 汇编代码，外部存储空间配置 OPTION.S 汇编代码，一些汇编宏定义：RAM的起始地址，中断入口表地址、RAM类型、系统主频、PLL控制字等 44B.H S3C44B0X的寄存器地址宏定义 OPTION.h 供C程序使用的一些反映系统工作方式的基本宏定义 Def.h 一些数据类型的缩写--HM701NEP(S3C44B0X) basic startup code. Based on it, you could do various experiments. It includes 6 files: 44BINIT.S/Memcfg.s/OPTION.S/44B.H/OPTION.h/Def.h .

运行在powerpc上的嵌入式linux-running on the embedded Linux

Discussing embedded systems in general is difficult, because each embedded system is unique. Rather than presenting a list of general principles for handling embedded development issues, this book presents examples of problems encountered and solutions to those problems using real hardware and software. In that sense, it is a “cookbook” for developers that offers design “recipes” that can be elaborated on or modified as needed to solve other design problems.
