A very handy tool to convert/search between ascii strings/characters and corresponding ascii values.
This simple utility is implemented with C, using standard libraries stdio.h, stdlib.h and string.h only, which lends enough portability among various platforms. It's designed for coding especially for embedded coding. If you often deal with massive, tedious VPD field programing with Hex or Decimal data format, this utility should be helpful to transform or validate data.
Just go with gcc/clang or any other C compiler following C99/C11/C14 standard, the executable ascii under folder ./bin/MacOS is compiled by clang of MacOS Mojave with -O2 level compiler optimization. If you are Mac users, use this executable directly.
Only --help, -h or -? option given will get help usage, otherwise, the argument will be treated as an input string.
Command doesn't take Null argument, so if no argument is specified, default argument is whitespace.
Utility can detect input data format, if a string number containing character A-F or a-f is given, string will be taken as Hex data, otherwise, it wil be taken as Decimal data, you can also add prefix 0x/0X or suffix h/H to mark it as a Hex format data string.
If some invalid data is taken, wrong-format error message will be printed.
If input data exceeds 127, overflow error message will be printed.
