#149206 - How common is 2 Byte ASCII HEX? |
I know I am not a programmer and hobby'ing does not count for much.
But writing code for my little project I have been following a technical document where it says each byte will be transmitted as 2 byte ASCII HEX! It took me some time to figure what was meant. Only today speaking with a programmer did I find out that as well as splitting the lower and upper four bits prefixing with 0011 to provide ASCII characters, if the 4 bits are over 9 (dec) then it becomes prefix with 0101 to give A, B, C etc. How common is this, I guess as in my project we are dealing with serial data that could be viewed on a terminal etc., but wonder about the wider area.
