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

[kilgorq]

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.

I figured it out.

1. The issue was the library. I ended up adding a dtostrf library to my libraries.

2. Was actually a switch in my UTFT library that had to be changed for CTE sheild with DUE.

// Uncomment the following line if you are using this shield
//#define CTE_DUE_SHIELD 1
