asciitohex adjust to end string correctly

[jps1x2]

HI mcore1976!

Function asciitohex is finishing string 2 chars after last written hex value. I am playing with your code and making some adjustements.

File: cc1101-tool-esp32-wroom.ino
Line: 103 hex_ptr[(2*i)+2] = '\0' ;
Correction: hex_ptr[(2*i)] = '\0' ;

Reason: variable i exits incremented from previous for bucle.
When code reaches line 103, i variable has the needed value to finish string fine adding \0, it is not needed to add 2 more char positions to it.

Regards!

I did not test it but I used this line 103 to put NULL into the string (array of chars) just in case

I can confirm that the correction is safe.

A similar situation arises in the last line of hextoascii:
ascii_ptr[i++] = '\0';
can be modified to:
ascii_ptr[i] = '\0';

The case I mentioned is more of a formality, while the solution for the asciitohex function is an improvement as it prevents the addition of a blank space.
