At the beginning to control servomechanism it needs to be defined. To do this
command.
SPI (Serial Peripheral Interface) is used to provide communication between
Arduino Uno board and WiFly shield. After defining SC16IS750 register definitions we
need to initialize Arduino pins over which communication will take place.
Next are the pins that are used when reset button and supervising LED are used.
pinMode(ledPin, OUTPUT);
digitalWrite(inPin, HIGH);
pinMode(MOSI, OUTPUT);
pinMode(MISO, INPUT);
pinMode(SCK,OUTPUT);
pinMode(CS,OUTPUT);
pinMode(photoPin, INPUT); // setting input pin
digitalWrite(CS,HIGH); //disable device
SPCR = (1<<SPE)|(1<<MSTR)|(1<<SPR1)|(1<<SPR0);
clr=SPSR;
clr=SPDR;
delay(10);
Serial.begin(9600);
myservo.attach(9);
myservo1.attach(8);
myservo.write(myservo_pos);
myservo1.write(myservo_pos);
