Arduino入門：その他の入出力関数

//Arduino Sketch Example: shiftOut
//Date: 2015.1.18
//Edited and Modified by: easy labo
//Original Source: Arduino Reference (http://arduino.cc/en/Reference/HomePage)

//Syntax
shiftOut(dataPin, clockPin, bitOrder, value)

//Parameters
//dataPin: the pin on which to output each bit (int)
//clockPin: the pin to toggle once the dataPin has been set to the //correct value (int)
//bitOrder: which order to shift out the bits; either MSBFIRST or LSBFIRST.
//(Most Significant Bit First, or, Least Significant Bit First)
//value: the data to shift out. (byte)

//Note
//The dataPin and clockPin must already be configured as outputs by a call to pinMode().
//shiftOut is currently written to output 1 byte (8 bits) so it requires a two step operation to output values larger than 255.

// Do this for MSBFIRST serial
int data = 500;
// shift out highbyte
shiftOut(dataPin, clock, MSBFIRST, (data >> 8));  
// shift out lowbyte
shiftOut(dataPin, clock, MSBFIRST, data);

// Or do this for LSBFIRST serial
data = 500;
// shift out lowbyte
shiftOut(dataPin, clock, LSBFIRST, data);  
// shift out highbyte 
shiftOut(dataPin, clock, LSBFIRST, (data >> 8));

//Arduino Sketch Example: shiftIn
//Date: 2015.1.18
//Edited and Modified by: easy labo
//Original Source: Arduino Reference (http://arduino.cc/en/Reference/HomePage)

//Syntax
byte incoming = shiftIn(dataPin, clockPin, bitOrder)

//Parameters
//dataPin: the pin on which to input each bit (int)
//clockPin: the pin to toggle to signal a read from dataPin
//bitOrder: which order to shift in the bits; either MSBFIRST or LSBFIRST.
//(Most Significant Bit First, or, Least Significant Bit First)

//Returns: the value read (byte)

//Arduino Sketch Example: pulseIn
//Date: 2015.1.18
//Edited and Modified by: easy labo
//Original Source: Arduino Reference (http://arduino.cc/en/Reference/HomePage)

//Syntax
pulseIn(pin, value) 
pulseIn(pin, value, timeout)

//Parameters
//pin: the number of the pin on which you want to read the pulse.(int)
//value: type of pulse to read: either HIGH or LOW. (int)
//timeout (optional): the number of microseconds to wait for the pulse to start; default is one second (unsigned long)

//Returns
//the length of the pulse (in microseconds) or 0 if no pulse started before the timeout (unsigned long)

//Example
int pin = 7;
unsigned long duration;

void setup()
{
  pinMode(pin, INPUT);
}

void loop()
{
  duration = pulseIn(pin, HIGH);
}

//Arduino Sketch Example: tone
//Date: 2015.1.18
//Edited and Modified by: easy labo
//Original Source: Arduino Reference (http://arduino.cc/en/Reference/HomePage)

//Syntax
tone(pin, frequency) 
tone(pin, frequency, duration)

//Parameters
//pin: the pin on which to generate the tone
//frequency: the frequency of the tone in hertz - unsigned int
//duration: the duration of the tone in milliseconds (optional) - unsigned long

//Arduino Sketch Example: noTone
//Date: 2015.1.18
//Edited and Modified by: easy labo
//Original Source: Arduino Reference (http://arduino.cc/en/Reference/HomePage)

//Syntax
noTone(pin)

//Parameters
//pin: the pin on which to stop generating the tone
