说明：  用单片机来直接驱动步进电机很精确走小步子.(Using single-chip to directly drive stepper motor is very accurate take small steps.)

实现图像的jpeg无损压缩，可以在linux系统下经过交叉编译器编译后在arm上实现，已经写好makefile文件(Realize jpeg image lossless compression, you can linux system through cross-compiler to compile in the arm to achieve, has written makefile file)

霍夫曼编码的C++实现，含word详细叙述文档，详细注释。(Huffman coding C++ to achieve, including the word detailed description of the documents, detailed notes.)

压缩的所有文件,解压缩的所有文件(zip unzip)

用c语言编写的无损压缩中的熵编码的编码和解码程序！ 很实用的！(prepared by the lossless compression of the entropy coding coding and decoding process! Very practical!)

哈夫曼编码(Huffman Coding)，又称霍夫曼编码，是一种编码方式，哈夫曼编码是可变字长编码(VLC)的一种。Huffman于1952年提出一种编码方法，该方法完全依据字符出现概率来构造异字头的平均长度最短的码字，有时称之为最佳编码，一般就叫做Huffman编码(有时也称为霍夫曼编码)。(Huffman encoding (Huffman Coding), also called Huffman Coding, is a way of Coding, Huffman Coding is variable word length Coding (VLC). Huffman in 1952 put forward a kind of coding method, this method is completely based on the characters of the occurrence probability to construct the average length of the shortest code word, sometimes called the best coding, generally is called Huffman coding (sometimes referred to as the Huffman coding).)
