Help on sending IR Codes

[espruino-discuss]

Posted at 2017-02-24 by navas

Hi,

I was trying to send IR code for my Aircondition unit. Unfortunately, none of the methods (hopefully) listed on the espruino website works for me, I was able to deduct the IR code using Arduino and found the following code.

Hash:  FA36E9A0 For IR Scope/IrScrutinizer: 
+4400 -4350 +550 -1600 +600 -500 +550 -1650 +550 -1600 +550 -550 +550 -550 +550 -1600 +550 -550 +550 -550 +550 -1600 +550 -550 +550 -550 +550 -1600 +550 -1600 +600 -500 +550 -1650 +550 -550 +550 -1600 +550 -1600 +600 -1600 +550 -1600 +550 -550 +550 -1600 +600 -1600 +550 -1600 +600 -500 +550 -550 +550 -550 +550 -500 +600 -1600 +550 -550 +550 -500 +600 -1600 +550 -1600 +600 -1600 +550 -550 +550 -500 +600 -500 +550 -550 +550 -550 +550 -500 +600 -500 +550 -550 +550 -1600 +600 -1600 +550 -1600 +550 -1650 +550 -1600 +550 -127976 

For Arduino sketch:  unsigned int raw[100] = {4400,4350,550,1600,600,500,550,1650,550,1600,550,550,550,550,550,1600,550,550,550,550,550,1600,550,550,550,550,550,1600,550,1600,600,500,550,1650,550,550,550,1600,550,1600,600,1600,550,1600,550,550,550,1600,600,1600,550,1600,600,500,550,550,550,550,550,500,600,1600,550,550,550,500,600,1600,550,1600,600,1600,550,550,550,500,600,500,550,550,550,550,550,500,600,500,550,550,550,1600,600,1600,550,1600,550,1650,550,1600,550,};

 irsend.sendRaw(raw,100,38);

How do I send the equivalent code from Espruino? (there is no pronto code listed on irdb.tk)

Thanks
Navas

Hi - are you doing this with a normal Espruino, or Puck.js?

On normal Espruino it should be as easy as:

var pulseTimes = [4400,4350,550,1600,600,500,550,1650,550­,1600,550,550,550,550,550,1600,550,550,550,550,550,1600,550,550,550,550,550,1600­,550,1600,600,500,550,1650,550,550,550,1600,550,1600,600,1600,550,1600,550,550,550,1600,600,1600,550,1600,600,500,550,550,550,550,550,500,600,1600,550,550,550,500,600,1600,550,1600,600,1600,550,550,550,500,600,500,550,550,550,550,550,500,600,500,550,550,550,1600,600,1600,550,1600­,550,1650,550,1600,550].map(function(x) {return x/1000;});

analogWrite(IR_ANODE,0.9,{freq:38000});
digitalPulse(IR_CATHODE, 1, pulseTimes);
digitalPulse(IR_CATHODE, 1, 0);
digitalRead(IR_ANODE);

So all I did is divide the times by 1000 to get them in milliseconds rather than microseconds.

Hi Gordon,

Thanks for responding. Actually the AirCon. has a longer IR Codes, It has 199 bits. So far I only found appropriate code for OFF :(

Is there any way I can decode longer IR signals, I am always getting memory out of error using Espruino using official decoded method (like the instructions on Youtube)

Thanks

Also, I finally figured out the code using espruino. It works with Puck.JS, but ot doesn't work on my Pico, Any ideas?

It is working on the official Espruino Pico. Still trying to figure out on ESP8266.

Thanks

ESP8266 won't work I'm afraid - it can't generate the 38kHz oscillation needed at the moment with its software PWM.

If you want to save some memory, you can do:

var off = new Float32Array([4.44984436035,4.37164306640 .... ]);

It'll put the data into a typed array, which will be much more memory-efficient.

Thanks @gordon.

I ended up using arduino for the IR part. It's so unfortunate that esp8266 on espruino sucks at pwm. Hope it won't be any problem on ESP32.

Thanks

Or you could use Espruino WiFi, which would work perfectly :)

Yup!, that's what I did for one of my AC. And for another one, I ended up using Arduino.

My budget is tight, so I can't afford to have multiple espruino Wifi :(

I heard there is a way to use IRQ and make it work on esp8266. Is there any work in progress?

I miss RGB Control (not the neo pixel) and IR stuffs since it lacks PWM support. Those are the two things I use mostly.

Thanks

Not as far as I know. I'm trying to use the patreon page to get some funds to look into ESP8266 a bit more, so I guess at some point that might happen.

However I think at some point WiFi takes priority over everything, so it might never be reliable.

since it lacks PWM support

Soft PWM does work ok. It seems to be ok-ish for ~100Hz or so, which might work for your lighting?

Here you go buddy.

Thanks for letting me know the patreon page.

And for RGB, controlling individual pins with each 100Hz works? I tried with one and seems like worked with OK, but haven't tried with all 3 pins.

Thanks! That's great!

Yes, 3x 100Hz should work ok - it might glitch very occasionally, but it's usable.

The way it's implemented, 3x 100Hz has about the same load as 1x 300Hz - so it should be fine. If you need more PWM you could always try lowering the frequency.
