I think this sketch is a carry over from the Arduino documentation. If I am correct the Arduino does not require the use the pinMode(pin_num, INPUT_ANALOG) initialization.</p> <p>When the Maple is programmed what are the subtle ("hidden") consequences if pinMode() is not called before analogRead() is used?</p> <p>Thanks!</p> <p>Stephen from NYC</p> <p>Here is a description of my system:</p> <p>Maple board: Rev 3 (summer 2010)<br /> Maple IDE: 0.6.0</p> <p>Processor: Pentium III (1 GHz)<br /> USB ports: 1.1</p> <p>OS: Windows XP Professional (32-bit)<br /> SP: Service Pack 3</p> <p>Java type: JDK and JRE<br /> Java version: 1.6.0_20 (as reported by the Control Panel) </p>
