hex coding

In embedded development, compiler-generated target files are generally. hex files.Why to convert, direct use of hex file not, but I have been in the development process is directly generated hex files, and then download, also did not see an

First, what is hexThe hexadecimal representation of each byte represents the content, displayed in a string.Second, the roleConverts an invisible, complex array of bytes data into a string data that can be displayedSimilar to BASE64 encoding

The coding methods and problems of win, PY, notepad++ first to say the conclusion: Because the default encoding used by Win CMD is GBK (ANSI), if it encounters bat or Python's Chinese needs to be displayed in cmd, if garbled, first check

Copy Code code as follows: Import java.io.UnsupportedEncodingException; Import Java.net.URLDecoder; Import Java.net.URLEncoder; Import org.apache.commons.codec.DecoderException;Import org.apache.commons.codec.binary.Base64;Import

UTF-8 is a Unicode implementation, that is, its byte structure has special requirements, so we say that a Chinese character range is 0x4e00 to 0x9fa5, refers to the Unicode value, as for the utf-8 in the code to be organized by three of bytes, So it

This article describes the PHP implementation of the color hex value converted to RGB method. Share to everyone for your reference, specific as follows: function Hex2rgb ($colour) { if ($colour [0] = = ' # ') { $colour = substr

This conversion in our daily coding still have a chance to meet, and here to share with you to discuss.void Pu_hex_to_binary (std::string strhex, std::string &strbinaryresult) {for (int i = 0; i = chtemp && chtemp >= ' a ') Chhexvalue = chtemp-' a '

Unicode,gbk,utf-8 differencesIn simple terms, UNICODE,GBK and five yards are encoded values, and utf-8,uft-16 is the expression of this value. And the preceding three kinds of coding is a compatible, the same Chinese character, that three code value

1. ASCII code We know that inside a computer, all information is ultimately represented as a binary string. Each bits (bit) has 0 and 12 states, so eight bits can combine 256 states, which is called Byte. That is, a byte can be used to represent 256
