Problem using while statement. Please help

Former Member
Former Member over 11 years ago

I am receiving a signal from ir receiver based on the receiver value, I am using a function in void loop(). In this function I am again receiving ir value and using switch statement to direct it to a case. Within that case I am using while statement (I am again receiving ir values) to run this function for two minutes. But the statements within the while statements are not running. Please help what I am doing wrong. My program is as follows.

 

#include <Wire.h>

#include <Adafruit_MotorShield.h>

#include "utility/Adafruit_PWMServoDriver.h"

#include <IRremote.h>

// Create the motor shield object with the default I2C address

Adafruit_MotorShield AFMS = Adafruit_MotorShield();

// Or, create it with a different I2C address (say for stacking)

// Adafruit_MotorShield AFMS = Adafruit_MotorShield(0x61);

// Select which 'port' M1, M2, M3 or M4. In this case, M1

Adafruit_DCMotor *myMotor1 = AFMS.getMotor(1);

Adafruit_DCMotor *myMotor2 = AFMS.getMotor(2);

Adafruit_DCMotor *myMotor3 = AFMS.getMotor(3);

Adafruit_DCMotor *myMotor4 = AFMS.getMotor(4);

 

// You can also make another motor on port M2

//Adafruit_DCMotor *myOtherMotor = AFMS.getMotor(2);

 

int RECV_PIN = 11;

 

IRrecv irrecv(RECV_PIN);

 

decode_results results;

void setup()

{

  Serial.begin(9600);

  irrecv.enableIRIn(); // Start the receiver

  AFMS.begin();  // create with the default frequency 1.6KHz

//AFMS.begin(1000);  // OR with a different frequency, say 1KHz

  if (irrecv.decode(&results)) {

Serial.println(results.value, HEX);

  }

}

void loop()

{

  if (irrecv.decode(&results)) // have we received an IR signal?

 

  {

Serial.println(results.value, HEX);

    translateIR2();

 

    irrecv.resume();

  }

}

void translateIR2() {

  if (irrecv.decode(&results))

switch(results.value)

 

    {

 

    case 0x21:

      unsigned long sec;

      unsigned long A;

      A=millis();

      while(sec < 120000){

       // Statements…;

sec=millis()-A;

Serial.println(sec,HEX);

        break;

      default:

Serial.println(" other button ");

      }

    }

}

    That may well fix the problem
