TMS320F281x Ecan 开发例程(Development of routines TMS320F281x Ecan)

说明：  Pokeface 题目描述 魔术师将一叠扑克顺次在桌上排成一行，初始全部正面朝上。随后，他每次挥一挥衣袖，都会翻转一连串的扑克，改变它们的正反朝向。从古代传下来的规矩，魔术师皆有师傅，他们要随时准备回答师傅的问题。问题形如：目前从第i张扑克牌到第j张扑克牌中，有几张正面朝上？ 作为魔术师的助手，你被要求学习程序设计、算法与数据结构。现在，魔术师把这个问题交给了你，你需要编写一个程序，维护相应的数据结构来保存桌子上牌面的情况，同时对于师傅的每一个问题，你要用尽量快的速度计算出答案。 输入 第一行包含三个正整数n、p和q。n表示扑克牌的数量，p表示魔术师的挥一挥次数，q表示师傅的问话次数。 接下来共p+q行，每行包含一个操作，操作分为2种： H i j 魔术师挥一挥，改变了第i张牌到第j张牌的正反 Q i j 师傅问话：截至目前，第i张到第j张牌中有多少张正面朝上 操作中恰好包含p次H操作，q次Q操作，与第一行的p和q吻合。H操作和Q操作的范围均包含边界（即第i张和第j张牌）。 对于每个操作，输入保证1 ≤ i ≤ j ≤ n。 输出 对于每次Q操作，输出一行，包含一个整数，表示问题的答案。 提示：线段树(Pokeface Title Description The magician will stack poker table sequentially in a row, all the initial face-up. He then every wisp will flip a series of poker pros and cons of changing their orientation. The rules handed down ancient times, the master magician Jie, they be ready to answer the teacher s questions. Question of the form: Currently playing cards i to j-card poker, there are a few face-up? As a magician s assistant, you are required to learn programming, algorithms and data structures. Now, the magician put this question to you, you need to write a program to maintain appropriate data structure to hold the cards on the table face the situation, while the master for each question, and you want to use as quickly calculate the answer. Enter The first line contains three positive integers n, p and q. n represents the number of poker, p represents the wave of the magic number, q represents the number of master s questioning. Next, a total of p+ q rows, each containi)

这是DSP F2812的CAN总线功能配置程序，希望对大家有用！(This is a DSP F2812 features CAN bus configuration program, we hope to useful!)

单片机dspic33fj128gp310， 使用DMA+ADC采样 DMA缓冲区以分散集中模式写入(dspic33fj128gp310 DMA+ADC DMA buffer is written to distribute centralized mode)

很好的东西，关于回波对消的代码，非常不错...(Good things about echo cancellation code ...)

说明：  DSP开发全过程经典，好的ＤＳＰ开发书籍(DSP Book)

可用利用simulink产生spwm代码，下载到F28335中，亲测可用，适用于MATLAB2013B及以前的版本(You can use Simulink to generate SPWM code and download it to F28335, which is available for MATLAB2013B and previous versions.)

dsp2802x实现的用于光伏发电模拟的模拟器(PV emulator by dsp2802x)

1.写一个程序，它先接收一个字符串，然后显示其中数字符的个数、英文字母的个数和字符串的长度。 2.模拟密码输入：假设数据库中有密码5201314，用户输入一个字符串，显示的时候全都以*出现，然后判断用户输入的字符串是否与数据库中密码相同，若相同，输出“Password Right!”，否则输出 “Password Error!” 3.写一个程序，它先接收一个字符串，然后抽去其中的空格，最后按相反的顺序显示这个改变后的字符串。 4.找出负数的个数 5.求阶乘(1. Write a program that first receives a string and then displays the length in which the number of characters and English letters and the number of strings. 2. Analog password: 5201314 suppose password, the user enters a string of all time display to* appear, and then determine if the string entered by the user and the same password , if the same output Password Right! otherwise, output Password Error! 3. Write a program, it first receives a string, and then removing all spaces, and finally display the string in reverse order after this change. 4. Find the number of negative 5. factorial)
