I’m using Sparkfun’s SEN-08554 IR receiver and remote to control a clock that I’m making. However, I’m having a little trouble implementing the code for the IR receiver.

I’m using Ken Sherriff’s library and the code that Sparkfun provided:

Code: Select all

#include <IRremote.h>

int RECV_PIN = 46; //pin 46 for the Mega2560
IRrecv irrecv(RECV_PIN);
decode_results results;
#define A 0x10EFF807

void setup()
{
  Serial.begin(115200);
  irrecv.enableIRIn(); // Start the receiver
}

void loop() 
{
  if (irrecv.decode(&results)) 
  {
    if (results.value == A) 
    {
      Serial.println("A");    
    }
    irrecv.resume();
  }
}

For the ease of reading, I trimmed the code down to just the one “A” button, but all buttons are in the code. Running that code on my Mega works great. So all the hardware is fine. It’s when I add it to my clock sketch that the problems arise.

What I’m trying to do is display my clock code in the main loop (time and date displayed from a DS3231 RTC), and then bring up a settings menu with a button press on the remote. It doesn’t seem to work.

What I’d like is for the menu function to be called when button “A” is pressed, but otherwise run the rest of the code in my main loop:

Code: Select all

void loop() 
{
  if (irrecv.decode(&results)) 
  {
    if (results.value == A) 
    {
      Serial.println("A");  
	buttonAPressed():  //call this function when “A” is pressed
    }
    irrecv.resume();
  }

//no IR codes rec’d, continue displaying main clock display
	//regular clock display code goes here
	//blah
	//blah
	//blah
}

void buttonAPressed {

//display settings menu
	//blah
	//blah
	//blah
}  

However, if I do it like that, my clock code/display shows fine, but buttonAPressed is never called. I can’t figure out why.

If I place my clock display code within “if (irrecv.decode(&results))”, the remote works, but the clock display code is only displayed when a button is pressed. I need that code to run when nothing is pressed! It's like I get what's either in “if (irrecv.decode(&results))” or the main loop, but not both.

Code: Select all

void loop() 
{
  if (irrecv.decode(&results)) 
  {
    if (results.value == A) 
    {
      Serial.println("A");  
	buttonAPressed():  
    }
    irrecv.resume();
  
//regular clock display code here
//blah
//blah
//blah
 }
}

void buttonAPressed {

//display settings menu
	//blah
	//blah
	//blah
}  

I've tried sticking "irrecv.resume();" in various places, but it doesn't seem to make a difference.

I even tried handling the remote in a separate function like this

Code: Select all

void loop() {
  if (irrecv.decode(&results))   {
    handleRemote(&results):  //I think I pass "&results" here?
    }
    irrecv.resume();
  }

//regular clock display code here
//blah
//blah
//blah
 }

void handleRemote() { //or is it void handleRemote(&results)? I think I tried various things without success
if (results.value == A) 
    {
      Serial.println("A");  
	buttonAPressed():  
    }
}

But that still doesn't get called. What am I doing wrong? I've been at this for days and I just can't get the loop to run as normal, but step into another function when a button is pressed.

Those delays are not doing you any good. If your are pressing the button while during a 'delay' it's not going to register it (especially the delay of 30 secs). I will admit I just skimmed over the code, maybe someone who has experience with RTCs will reply.

Correct. I actually took that already. I was thinking that I'd allow the GPS to stream for 30 seconds to allow it enough time to link, but then I realized that that's dumb because it'll jam up the clock for 30 seconds while it's doing it. But that's not the problem. The problem is that I can't call any function from the remote.

[Ross Robotics]

Have you tested the remote to see if it's actually working and triggering code?

[ryemac3]

The remote works fine when it's just the blank sketch provided by Sparkfun. I can see A, B, C, etc in the serial monitor. But when I paste that code into my sketch for the clock, it doesn't work. It only works when I embed all my loop code within the "if (irrecv.decode(&results))" code. But that's useless since none of the clock code will run until a button is pressed on the remote. The clock code should run in the loop until an IR code is received, then "if (irrecv.decode(&results))" should capture the code and fire off the corresponding function.

Have you put some debug Serial.println("got here"); in places below the if (irrecv.decode(&results))
statement to see that the code is running and getting to all the places it should be ?

Something very odd is going on so start by confirming that even the obvious "has to work" code is actually working.

Yes, I''ve tried that. That's how I know nothing is being called. No message show up on the serial monitor when all the clock code is in the sketch.

Very strange stuff going on. If I do this, and only this, it totally works:

Code: Select all

#include <IRremote.h>
#include <glcd.h>
#include <fonts/allFonts.h>

int RECV_PIN = 46;
IRrecv irrecv(RECV_PIN);
decode_results results;
#define A 0x10EFF807 
#define B 0x10EF7887
#define C 0x10EF58A7
 
void setup() {
  GLCD.Init();
  Serial.begin(115200);
  irrecv.enableIRIn(); // Start the receiver
  
}
 
void loop() {
  GLCD.SelectFont(System5x7);
  
  if (irrecv.decode(&results)) 
  {

    if (results.value == A) 
    buttonA();
    {
      Serial.println("A");    
    }
    if (results.value == B) 
    {
      Serial.println("B");  
      buttonB();
    }
    if (results.value == C) 
    {
      Serial.println("C");
      buttonC();
    }
   
    irrecv.resume();
  }
}

void buttonA() {
  
  GLCD.print("button A pressed");
}

void buttonB() {
  
  GLCD.print("button B pressed");
}

void buttonC() {
  
  GLCD.print("button C pressed");
}

Each subsequent button press (A, B, or C) calls a function that displays a text message on the LCD. It works. So it's not a hardware thing. Why do these functions get called, but not once I add all my RTC code?

[ryemac3]

Ha! I think I figured out where the problem is. If I eliminate this code from my loop, it works:

Code: Select all

DateTime now = RTC.now();
  tempC = RTC.getTemperature();
  tempF = (tempC * 9.0)/ 5.0 + 32.0; // Convert C to F

  hhRTC = now.hour(); //used to check AM/PM status
  mmRTC = now.minute();
  ssRTC = now.second(); 

  dowRTC = now.dayOfWeek();
  dayRTC = now.date();
  monthRTC = now.month();
  yearRTC = now.year();

But then I don't have data from the DS3231 RTC. So it's something in the Wire library that steps on the IR Receiver library. I tried both SDA/SCL ports on the Mega. Again, not a hardware thing.

I searched for a new IR library and found this.

I popped this code it

Code: Select all

void loop()                    
{
   if (My_Receiver.GetResults(&My_Decoder)) {
       My_Decoder.decode();
          switch(My_Decoder.value) {
            case A:   buttonA();    break;
            case B:   buttonB();    break;
            case C:   buttonC();    break;
          }
     My_Receiver.resume();
    }

void buttonA() {
 Serial.println("A"); 
}

void buttonB() {
  Serial.println("B"); 
}

void buttonC() {
  Serial.println("C"); 
}

And so far my RTC is running on screen, and the IR signals are being received and the corresponding functions are being called. Looks like it's working with the new library. It's not perfect and every now and then a code slips, but it's better than it was.

I think there's something between the IR library and the Wire library that don't work well together. I'm going to try and find a way to pull the RTC clock stuff out of the main loop and see if that helps.

In any case, does anyone know what in the Wire library could interfere with the IR library? I wanted to look at the header file but I can't seem to find where the Wire library is on my Mac.
