Yes, but if you do, it is not a portable operation.
ASCII for K is 0x4b = 75 = 0100 1011
That's because the inventor of ASCII code thought they are important characters.
First of all ASCII is encoding system that tells how binary data from file could be represented as text. Is was and still is very widely used starting 1960s. Standard ASCII encoding is 7-bits encoding allowing 128 values, while Extended ASCII is 8-bits encoding which allows 256 values, that is 128 more characters in the table. First 128 Extended ASCII table characters is the same as ASCII table, next 128 is additional characters.
Extended ASCII is 8-bit encoding which is wider than standard ASCII and also includes all characters from standard ASCII encoding.ASCII is 7-bit, 128 possible values; Extended ASCII is 8-bit , 256 possible value;128 first characters of Extended ASCII is the same as ASCII, next 128 are additional. This why it is called Extended ASCII.What is ASCII?ASCII is mainly English language characters encoding, that is used for representation of text information.
There is no ASCII value of :-) ASCII encodes only single characters, assigning a numerical 0-127 value to each character. However, if you want the ASCII encoding of a smiley, here's some samples (using Hex values): :-) 0x3A2D29 :) 0x3A29
Binary- 01100111 Decimal Value- 103
You can find the ASCII value of numbers greater than 9 using the following functions: std::to_string or boost::lexical_cast or std::ostringstream depending on the compiler that you are using.
If you look up the ASCII values for digits, you'll see that 0 = 48, 1 = 49... 9 = 57. So it's a simple matter of adding 48 to your digit to find out the ASCII value for it.
Ascii is not a protocol - it describes a computer system's character set. Communication with a Modbus PLC requires an understanding of how to communicate and the protocol (set of rules) does describe this. Ascii is a set of values describing the Latin codepage set that can represent certain characters in data. There are no communications "rules" with Ascii, just a data representation.
No.ASCII stands for American Standard Code for Information Interchange. It couldn't be called a standard if it varied from machine to machine.Note that this only applies to the core ASCII values. Some machines/programs/formats will use a subset or extended set of ASCII codes.
Because certain standards such as ASCII have different values than an Asian character set. for example, if the letter (Asian letter here) is represented by 129h in an Asian character set, then when 129h is tried to be put into ASCII, it fails, because 129h is not a valid character in ASCII, and is then shown as a box.
