Character type: Assigns a value (prefix \u) to a character variable by a hexadecimal escape character (prefix \x) or Unicode notation.
In fact, it can be understood that "the display declared a 16-bit integer conversion to char" because C # cannot convert an integral hermit to char Char
such as: Char c= ' \x0032 '; //Char c= ' \u0032 '; //
Test code:
private void Button1_Click (object sender, EventArgs e){char c1 = ' \u0032 ';char c2 = ' \x0032 ';

An Intel HEX file is an ASCII text file that records text lines. In an Intel
Conversion between JAVA Hex and string, and java hexToHexStringPublic static String toHexString (int I) returns the String representation of an integer parameter in the hexadecimal notation.If the parameter is negative, the unsigned integer is 232. Otherwise, the value is equal to the parameter. Convert the value to an ASCII numeric string without leading 0 in hexadecimal notation (base 16. If the value of the unsigned number is zero, it is expressed

The bad thing is this base64 strings are stored in a variable and there ' a limitations for it ' s size. But for a small strings it wokrs.

(The standard ASCII code is also called the base ASCII code, using a 7-bit binary number to represent all uppercase and lowercase letters, numbers 0 through 9, punctuation, and special control characters used in American English.) )
For the N-byte notation (n>1), the f

Note:A previous article translated during format conversion. At that time, I didn't know much about these things, so it was not good at translation. I have not been exposed to this information for about 3 or 4 years, so even if there is an error, it cannot be corrected now. I hope I will not be laughed at when I figure out my computer. Thank you for your criticism.
Problem:What is the intel
Hex files and binfiles are two common file formats. The following describes the differences between the two file formats:

HEX file format learning notes
In order to write a program that can perform ISP according to your own requirements, I learned about the Hex file format. Write the study notes to consolidate the learning content.
