说明：  cadence pcb设计工具的增强功能(Enhancement of cadence PCB design tool)

说明：  浮点数的表示与算术运算算法分析，要求理论推导与程序模拟。 算术运算包括字符串到浮点数、浮点数到字符串的转换，加、减、乘、除四则运算等。要有说明文档，包括算法证明、程序框图、使用方法、特殊处理(溢出、数位扩展)、实例分析等等。字符串转换可能稍难。 typedef unsigned int dwrd; #32-bit char* ftoa(dwrd); dwrd atof(char*); dwrd fadd(dwrd, dwrd); dwrd fsub(dwrd, dwrd); dwrd fmul(dwrd, dwrd); dwrd fdiv(dwrd, dwrd);(The representation of floating-point number and the analysis of arithmetic operation algorithm require theoretical derivation and program simulation. Arithmetic operations include string to floating point, floating point to string conversion, addition, subtraction, multiplication, division and so on. Documentation should be provided, including algorithm proof, program block diagram, usage, special handling (overflow, digital expansion), case analysis, etc. String conversion can be slightly difficult. typedef unsigned int dwrd; #32-bit char* ftoa(dwrd); dwrd atof(char*); dwrd fadd(dwrd, dwrd); dwrd fsub(dwrd, dwrd); dwrd fmul(dwrd, dwrd); dwrd fdiv(dwrd, dwrd);)

发现设备: PX4 FMU V2 飞控解码，刷写固件(Discovery device: PX4 FMU V2 Flight Control Decoder, Brush Firmware)

个人写的CC2530入门程序，以Z-stack协议栈为基础，涉及10个小程序，包括数据传输、串口首发、串口应用扩展、无线温度检测、协议栈NV操作、广播和单播通信、组播通信、网络管理、网络拓扑获取和数据采集

：好风格应该成为一种习惯。如果你在开始写代码时就关心风格问 题，如果你花时间去审视和改进它，你将会逐渐养成一种好的编程习惯。一旦这种习惯变成 自动的东西，你的潜意识就会帮你照料许多细节问题，甚至你在工作压力下写出的代码也会 更好。(: Good style should become a habit. If you write code at the beginning when the issue of concern for style, if you take the time to examine and improve it, you will gradually develop a good programming practice. Once this habit becomes automatic things, your subconscious will help you take care of many details, and even under the pressure of your work will be better to write code.)

说明：  rtthread nano的模板，有基本的内核部分，可以完成线程调度、信号量传递等等(rtthread nano have the core can do thread and transmit the signals)

详细介绍Ubuntu Linux的安装过程和方法，以及一些基础的配置方法。是Linux初学者的首选。(Details of Ubuntu Linux installation process and methods, as well as some basic configuration. Is the first choice for Linux beginners.)
