Trying to figure out how to update my libraries to not use dtostrf.

kilgorq:
Issue 1) 'dtostrf' was not declared in this scope

Works for me...

#include <avr/dtostrf.h>

void setup( void ) 
{
  char bufferWater[31];
  float WT;
  dtostrf(WT, 4, 0, bufferWater);
}

void loop( void ) { }

Obviously, the Arduino folks need to add that first line to Arduino.h for the Due.
