Erro ao compilar o codigo.
Boa tarde, galera.
eu estou testando meu arduino duemilanove atmega 328 + ethernet shield wiznet 5100.
Tentei compilar o seguinte código:
#include <WString.h>
#include <Ethernet.h>
/*
Simple Ethernet Test
Arduino server outputs simple text to browser
The circuit:
- Arduino Duemilanove
- Arduino Ethernet shield
- Basic FTDI breakout 5V
*LED connected to GND and digital pin 4 via resistor

byte mac[] = { 0xDE, 0xAD, 0xBE, 0xEF, 0xFE, 0xED }; //physical mac address

Só que ele me apresenta o seguinte erro:
ethtest.cpp: In function 'void loop()':
ethtest:46: error: 'class String' has no member named 'append'
ethtest:53: error: 'class String' has no member named 'contains'
Alguém pode me ajudar?
