Again, I inserted the sprintf() code into the example serial project that comes with the compiler. This is my code:

unsigned long num1 = 500;
char numstr1[5];
sprintf(numstr1, "Num 1 is %lu", num1);
se_print( numstr1 );

where the se_print() function expects a variable of type (const rom char *). This returns an error of "argument #2: memory spaces do not match", referring to the use of sprintf().

I looked again at the prototype for sprintf() and noticed that it expects a (const char *), so I declared const char *lu_str = "%lu"; and replaced the second argument of sprintf() with lu_str.

Now the error I get is "operands of '=' are not pointing to the same memory space" in reference to the declaration of lu_str.

Any ideas?
