QUESTION

How do I convert a constant passed to a #define macro into a text string?

ANSWER

Pass the parameter to a stringizing macro as shown below:

#define NUMBER B85800    // this can be defined in the command line

#define VAL(str) #str
#define TOSTRING(str) VAL(str)

unsigned char part1[10] = TOSTRING (NUMBER); // generates "B85800"
unsigned char part2[10] = VAL(NUMBER);       // generates "NUMBER"
