AD9850 DDS chip driver

研究了一种基于嵌入式系统和超声波测距系统的设计方案。应用移植嵌入式操作系统并给出障碍物检测优化方法，并且根据超声波测距的工作原对障碍物进行距离测量。实验结果表明，该系统在自然盲道情况下达到了处理实时性和判断的准确性要求，可较好地服务于盲人的独立出行。

TROCHILI内核是一个全新的适用于嵌入式领域的实时内核，它完全由C语言开发，支持多任务、多优先级、抢占式调度。TROCHILI的含义，取蜂鸟之意，意味着体积小巧、动作灵敏。

用于USB 适配器的源代码，值得一看he following is a series of code files comprising the bootcode for TUSB3210.  It is already resident in on-chip ROM and therefore was not intended for our customers to compile 揳s is?and execute on the  evaluation board.  Rather, it is provided  to serve as an example of how to program the device,  and excerpts of the code can be used in real  applications (for example, the I2C subroutines).  

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.
