首先通过文件操作,读取文件内容,把字符逐个提取后统计字符频率,建立哈夫曼树和进行哈夫曼编码,当然这是根据ASCII编码来将字符转换为二进制,然后实现前缀编码,然后把编码后的使用二进制流写入相应文件(First through file operations, read the file content, the characters one by one after extracting character frequency statistics, establish a Huffman tree and Huffman encoding, and, of course, this is according to ASCII code to convert characters to the binary, then realize the prefix encoding, and then the encoded using binary stream into the corresponding files

基于51单片机的HC-SR04超声波测距系统制作
超声波模块制作了一个测距装置,HC-SR04自身不带温度补偿功能,所以加上一个使用DS18B20做的温度测量模块。整个系统包括:51单片机最小系统,超声波测距模块、温度测量模块、液晶显示模块。(The ultrasonic module has made a distance measuring device, HC-SR04 does not have temperature compensation function, so add a temperature measuring module using DS18B20. The whole system includes 51 single chip microcomputer minimum system, ultrasonic ranging module, temperature measurement module and LCD module.)
