该压缩包为ARM S3C44B0的源代码，含有5个程序。分别为按键控制LED,PWM脉冲宽度调制,RTC实时时钟，UART串口通信，DMA直接内存存取等5个实验的源代码。代码以C语言为主，辅以部分ARM汇编指令。该实验开发平台为S3C44B0板，开发工具为ADS1.2.-The package for the ARM S3C44B0 compression source code, which contains five procedures. Were keys to control LED, PWM pulse width modulation, RTC real time clock, UART serial communication, DMA direct memory access, such as five experiments the source code. Code to C language, supplemented by some ARM compilation directives. The experimental development platform for S3C44B0 boards, development tools for ADS1.2.

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.
