The shell can represent different data in the system without invoking the 3rd party command. The following presentation method is summarized here. The default value of the shell script is handled by the 10 number, unless the number has a special notation or prefix at the beginning. Can be used to represent other types of values in the system. For example: Starting with 0 is 8. The beginning of the 0x is the 16 number. Using Base#number this form can r

This example describes the way PHP converts strings to 16. Share to everyone for your reference. The specific analysis is as follows: In PHP, you can convert a string into a 16-form output using the Bin2Hex function, and the Bin2Hex () function returns the ASCII code The output results are as follows: Hello world! 48656c6c6f09776f726c64210a I hope this article will help you with your PHP

Two of these methods allow you to easily implement conversions between the various values of the system: Convert.ToInt32 (string value, int frombase): You can convert a string of different values into numbers, where the frombase parameter is in the form of 2, 8, 10, and 16: If Convert.ToInt32 ("0010", 2) The result of execution is 2; convert.tostring (int value, int tobase): You can convert a number to a string format with different values, where the

For amateur badminton enthusiasts, in order to improve the skill in a short period of time, can use some more practical methods, below we recommend a 16 rule.1, strive to hit the front of the body, do not let the ball fall to the neck below the height, or return the ball will not attack.2, hold the clap as far as possible to keep relaxed, in order to maximize the strength of the wrist.3, in the singles, each shot should immediately return to the centr

Well, it's a pain in the egg. Code conversion problem: to the shape of the string as \XE9\XBB into Chinese ... In Python we can print "\xe9\xbb\x84" directly, In the shell we direct echo $ ' \xe9\xbb\x84 ' #echo-e ' \xe9\xbb\x84 ' is OK, Note: You cannot directly echo $ ' \xde\xab ' |iconv-f gbk-t utf-8, Because GBK words, \XE9\XBB is Hazel, the back of the \x84 only half word, will be an error or garbled, UTF8 is a variable length, accounting for 1~4 bytes, Chinese characters are generally 3 by

The premise is that the driver of the I2C controller must have been running normally, the standard I2C tool can only read and write to 8-bit address, but the EEPROM of this 16-bit address will be powerless So this kind of 16-bit address for read and write support, in the embedded domain is still very common The main use of standard Linux I2C interface, struct i2c_msg; I2C message data structure First, the I

First of all, the whole idea:Hex that contains decimals, we can first divide it into integers and decimal parts,Then the string comparison is made and the corresponding substitution is made.

This network to multi-port module can easily realize the data transparent transmission between network equipment and multiple serial devices.This scheme is based on fpga+w5500. The serial port part uses the serial data to send and receive the hardware accelerator, make full use of the buff and FIFO resources, and greatly improve the data scheduling ability of 16 serial port. At the same time, the network part uses Toe technology's W5500, thus greatly
