The PMSM FOC is made of several C modules, compatible with the free-of-charge IAR EWARM KickStart edition toolchain version 4.42. It is used to quickly evaluate both the MCU and the available tools. In addition, when used together with the STM32F103xx motor control starter kit (STM3210B-MCKIT) and PM motor, a motor can be made to run in a very short time. It also eliminates the need for time-consuming development of FOC and speed regulation algorithms by providing ready-to-use functions that let the user concentrate on the application layer. Moreover, it is possible to get rid of any speed sensor thanks to the sensorless algorithm for rotor position reconstruction.

This file contains a C++Builder 4 project called SimplyChaos-X ver 3.1 (SCX31). SCX31 is an encryption tool. I designed it as my graduation paper work. SCX31 is a symmetric stream cipher built on chaos function, one time pad cipher and inspiration from Ground Effect (aviation). The key length can be up to 40 characters (320 bits).

JLAB is a set of Matlab functions I have written or co-written over the past fifteen years for the purpose of analyzing data. It consists of four hundred m-files spanning thirty thousand lines of code. JLAB includes functions ranging in complexity from one-line aliases to high-level algorithms for certain specialized tasks. These have been collected together and made publicly available for you to use, modify, and --- subject to certain very reasonable constraints --- to redistribute. Some of the highlights are: a suite of functions for the rapid manipulation of multi-component, potentially multi-dimensional datasets a systematic way of dealing with datasets having components of non-uniform length tools for fine-tuning figures using compact, straightforward statements and specialized functions for spectral and time / frequency analysis, including advanced wavelet algorithms developed by myself and collaborators.

很完整的51串口程序 包括如下： 串口中断服务程序，仅需做简单调用即可完成串口输入输出的处理 出入均设有缓冲区，大小可任意设置。 可供使用的函数名: char getbyte(void) 从接收缓冲区取一个byte,如不想等待则在调用前检测inbufsign是否为1。 getline(char idata *line, unsigned char n) 获取一行数据回车结束，必须定义最大输入字符数 putbyte(char c) 放入一个字节到发送缓冲区 putbytes(unsigned char *outplace,j) 放一串数据到发送缓冲区，自定义长度 putstring(unsigned char code *puts) 发送一个定义在程序存储区的字符串到串口 puthex(unsigned char c) 发送一个字节的hex码，分成两个字节发。 putchar(uchar c,uchar j) 输出一个无符号字符数的十进制表示，必须标示小数点的位置,自动删除前面无用的零 putint(uint ui,uchar j) 输出一个无符号整型数的十进制表示，必须标示小数点的位置,自动删除前面无用的零 delay(unsigned char d) 延时n x 100ns putinbuf(uchar c) 人工输入一个字符到输入缓冲区 CR 发送一个回车换行

小程序应有如下功能： 1、登记。登记每位同学的上网卡号，押金(>=5 RMB)和上网时刻。 2、查询。可以查询每个上网卡号的上网时刻，上网的时间，押金和当前的费用。 3、结账。根据卡号可以算出 应收金额，应找金额。 4、提醒。当某个上网卡号的 上网费用 >= 它的押金时应提醒管理员。 5、续费。当某个上网卡号的 上网费用 >= 它的押金，他可以再次交上一定金额的押金(>=5 RMB)。 6、修改费率。上网的费率应可以调整。默认的费率是1 RMB /1小时。 为了不让机房赔本，应是这样的收费模式：先付钱后上网。如上机就五角， 以后过半小时收五角。 7、总账。一天下来管理员要知道这天他赚了多少RMB。 你需要考虑程序被意外结束等特殊情况。 如果你的程序是按系统时间进行计时，还应考虑系统时间被意外更改的特殊情况。总之，你应考虑一切会让你的程序不能正常运行的特殊情况。 如果不知道怎么计时，你可以学习参考使用<time.h>中函数。 说明： a. 假定机房有150台机器。 b. 假定初始的费率是1 RMB /1分钟(便于测试)。

Coaxial feed structures are widely used in ultra-wide band antennas . This paper modeled the characteristic of the monopole antenna feeded by coaxial line by FDTD in the time-domiain,which showes that . Firstly, it introduced the theory of the arithmetic and the particularly realization in the calculation then it described the use in the time-domain finally it analysed several characteristics of the monopole antenna. The arithmetic used in the microstrip antenna is also a quick and economical way to design the antenna.
