VS838 IR receiver led anyone got it working with mys?

[skywatch]

I just noticed a 'delay(100);' in the code above. It shouldn't be there, so will change it to 'wait(100);' and see if that was the problem - A new day a new try!

Well that wasn't the issue and I successfully combined the IRreceive and BH1750 sketches and all worked as expected. So something is happening when MySendors is involved, the question is what? - I'll continue to think on this and see what else I can think to try.

@skywatch
What is your memory usage?

[skywatch]

@electrik At compilation I get the following....

Sketch uses 21718 bytes (70%) of program storage space. Maximum is 30720 bytes.
Global variables use 1207 bytes (58%) of dynamic memory, leaving 841 bytes for local variables. Maximum is 2048 bytes.

It looks OK to me, but I have been wrong before (and will be again, probably quite soon ) ; ).

I have 2 other nodes that will also require IR Tx/Rx between them so will try and build them this weekend and see if I get the same issue.

[electrik]

You could also add debug prints at specific points so you find out where the code still runs.

edit To me the memory looks fine. Only if use a lot of stack it could give trouble, but it seems enough space is available

[skywatch]

@electrik It seems that the IR if statement is never actioned.

I added

Serial.println("Enabling IRin");
  irrecv.enableIRIn(); // Start the receiver
  Serial.println("Enabled IRin");

To setup and that seems to be OK....

But for some reason I can't find, it never executes the receive If code.
Also tried input pins D2.4,6,8 and all show the same lack of doing what they should!
Very strange!

@skywatch I found some time to rebuild your setup:
Arduino UNO, nRF24 default connection no IRQ, TSOP1738 connected to D6, Arduino IDE 1.8.10

Tested first with IRRecord sketch, same pinning, working fine.

Absolute bare minimum sketch, containing MySensors (2.3.2) and IR Receiver using the same library (current version):

#define MY_DEBUG

#define MY_BAUD_RATE (57600)
#define MY_RADIO_RF24

#define MY_RF24_CE_PIN              (9)
#define MY_RF24_CS_PIN              (10)

#define MY_NODE_ID                  (254)
#define MY_PARENT_NODE_ID           (0)
#define MY_PARENT_NODE_IS_STATIC

#include <Arduino.h>
#include <IRremote.h>
#include <MySensors.h>

const int RECV_PIN = 6;
IRrecv irrecv(RECV_PIN);

void presentation()
{
    Serial.println(F("-- Init MySensors"));
    sendSketchInfo(F("IRSensor"), F("1.0"));
}

void setup()
{
    irrecv.enableIRIn();
}

void loop()
{
    decode_results results;
    if (irrecv.decode(&results))
    {
        for (int i = 0; i < results.rawlen - 1; ++i)
        {
            Serial.print(results.rawbuf[i], DEC);
        }
        Serial.println();
        irrecv.resume();
    }
}

Added basic MySensors sketch, same pinning working fine:

I suggest to try with my sketch and see if that works.

BTW. Passing a LED pin to the constructor as status indicator doesn't seem to work, or my eyes are just too slow :smirk:

[skywatch]

@Yveaux I cannot thank you enough for doing this to try and help me out. It is really kind of you.
I am using 1.8.9 IDE as I had issues with 1.8.10 (as did others). Also I notice that you have forced 57600 as the baud rate in the sketch. Is this the magic bullet I wonder as I left mine at the default 115200 setting. I can't imagine why it would make a difference though.
I will be trying it shortly and will report back with anything I find.
I owe you a beer for sure! ;)

[Yveaux]

@skywatch said in VS838 IR receiver led anyone got it working with mys?:

@Yveaux I cannot thank you enough for doing this to try and help me out. It is really kind of you.

Glad I could help!

I am using 1.8.9 IDE as I had issues with 1.8.10 (as did others).

I didn't encounter any issues with 1.8.10 so far, but I don't expect it will make a difference in your case

Also I notice that you have forced 57600 as the baud rate in the sketch. Is this the magic bullet I wonder as I left mine at the default 115200 setting. I can't imagine why it would make a difference though.

57600 is the default baud rate at 3v3 for pro mini iirr. This might be related to when using the internal oscillator and the frequency errors introduced by it. But pro mini uses an external crystal so I have to dig the datasheets to know for sure. Maybe some other forum member knows it by heart...

I owe you a beer for sure! ;)

Great! That I will remember :laughing:

[skywatch]

@Yveaux Your code works.....until I add it to mine and then it stops working for some inexplicable reason that will drive me insane I think. ;)
I copied across your code line by line and still it refuses to 'see' any IR commands being received.

I have tried excluding the watchdog, excluding the bh1750, adding arduino.h and excluding wire.h and none of those make any difference.

[Yveaux]

@skywatch Maybe the cause lies outside your sketch; Are you using MySensors 2.3.2? Or do try with Arduino 1.8.10

[skywatch]

@Yveaux I have narrowed it down to a small section of code.....still working on it!

[skywatch]

@Yveaux Ihave 2 issues that I have identified, but can't work out the cause.

Issue 1 - No IR received seems to be caused by thise section of code. Commenting it out and it works as expected (but of course will never transmit).....

 if (newcodeRX == 1 || lightrequest == 1) {
    irsend.sendNEC(INcode, 32);
    newcodeRX = 0;
    lightrequest = 0; 
   }

Second issue, is when receiving IR is working I cannot do anything useful with it. I have tried 2 methods to get a value and perform a function with it and both fail. See the 2 methods tried here......

 decode_results results;

  if (irrecv.decode(&results)) {
    Serial.print("IR Received... ");
    Serial.println(results.value, HEX);
    IRin = (results.value, HEX);
    Serial.print(" IRin... ");
    Serial.println(IRin);
     irrecv.resume(); // Receive the next value
  }

  if (IRin == 0xFFA25D) {
    lights = 1;
    Serial.print("Lights ON... ");
  }

  if ((results.value, HEX) == 0xFFE21D) {
    lights = 0;
    Serial.print("Lights OFF... ");
  }

I need to eat now, will get back to this later on......

[skywatch]

Second issue now solved, just the first one to investigate.... ;)

[skywatch]

Both issues now resolved! :)

More to follow..... ;)

[skywatch]

So here is what I learned from all this....

Issue 1 - Was caused by the fact that IRsend was called at first boot - nothing wrong with that, but what I didn't know was that IRsend disables IR receive.
The solution was as simple as adding one more line to that section of code as follows.....

 if (newcodeRX == 1 || lightrequest == 1) {
    irsend.sendNEC(INcode, 32);
    newcodeRX = 0;
    lightrequest = 0; 
    irrecv.enableIRIn(); // Start the receiver
   }

This re-enables the receiver and then all is working as expected!

As for the second issue......Well, I'll just post the code for anyone interested.....

 if (irrecv.decode(&results)) {
    IRin = results.value,HEX;
    
  if (IRin == 0xFFA25D) {
    lights = 1;
    Serial.print("Lights ON... ");
  }

  if (IRin == 0xFFE21D) {
    lights = 0;
    Serial.print("Lights OFF... ");
  }

  if (lights != last_lights) {
    saveState(10, lights);
    send(msgLights.set(lights));
    last_lights = lights;
    }

     irrecv.resume(); // Receive the next value

  }

It's always soooooo easy when you know how! ;)

Onwards and upwards! :)

[Yveaux]

@skywatch great to hear you resolved your issues!

[skywatch]

Many thanks @electrik and @Yveaux , some moral support is often pivotal in getting things done!

@Yveaux IDE 1.8.12 is now available and working fine on win10 x64 for me :)
