float diff = 0; const char* str[] = {"Err: ZPROBE: ",diff}; LCD_ALERTMESSAGEPGM(str);
With the code above I get I get this error. Anyone know how to create a single string from "Err: ZPROBE: "
and a (float) diff
?
exit status 1 cannot convert 'float' to 'const char*' in initializatio
Sorry should add that in the environment i'm using - 'string' : is not a member of 'std',
Ok now trying this
String str = String("Err: ZPROBE: " , diff);
but get this
call of overloaded 'String(const char [14], float&)' is ambiguous

To convert float
or double
into a string
, you can use dtostrf()
which is available in the stdlib.h
header. Also see the reference of String Object Constructors to construct String
objects correctly.
