I built the simplest IR blaster to replace some functions of my infrared remote control for my Mitsubishi aircon model MSY-GE10VA. I go through some similar developer and consumer devices that are already available in the market to understand what technologies are used. Then I proceed to explain how to integrate the core functions of an infrared receiver and transmitter. A tiny demo shows how the configuration mode works with the WebUSB protocol. And finally, the aircon functions for turning ON and OFF are recorded and replayed from the custom PCB.

good! you just testing On and Off,how you can send a raw data just for the mode air conditioner or a raw data just for the temperature?? when you recieve the IR from the remote.the raw data containe the power and the mode and the temperatue

@sayanee 3 жыл бұрын

That will depend on the exact remote controller and the aircon model. Whatever it is set in the remote control, that exact feature will be recorded in the raw code. For example, even though I recorded ON and OFF, it seems that for my remote control and aircon model, the ON and OFF functions are also tied with a particular temperature. So, in this case I recorded ON 25 deg and OFF 25 deg.

my remote send all parametres power,temp and mode in the same raw.So, i will try to separate it and search a solution ;)

@@dhiaeddinesouai5334 Yeah I guess, most does combine a few of the factors together into one single raw code. Maybe you can try www.analysir.com/blog/get-analysir/ - I never tried it, but I keep hearing about them. You might need to dig into the infrared signals. Would be curious to know how you did it, if you ever manage to :) All the best!

How can I make universal ir blaster with esp 8266 with google assist

@henrycheung6960 3 жыл бұрын

Sayanee, great project. Why SAND21? it quite a little bit overkill for an IR controller.

@sayanee 3 жыл бұрын

Just something that I'm familiar with :) It takes quite a while to understand the ecosystem of a brand new micro-controller, it's architecture, toolchains, etc. Definitely, use whatever you know and optimise when it is appropriate. I also went for SAMD21G because I needed it's flash storage, periodic wakeup and USB peripheral to use with WebUSB. I explained more in this video (ATmega328p vs SAMD21G): kzfaq.info/get/bejne/rrxhn5iEyauco58.html

@@sayanee My choice of ARM-based MCU is STM32, for the same reasons you mentioned, toolchains, IDE, HAL libraries, etc. For 8-bit MCU, I've found a chip that not so well-known ATtiny3217 which has almost the same GPIO, features and functionality as ATmega328p, I created a board www.e-tinkers.com/2020/07/arduino-compatible-development-board-with-attiny3217/ and currently doing a second version, maybe I will come to talk about it in one of the upcoming Hackware Meetup and bring a couple of the boards as give-away... See you next time.

The ir code with IRLIB2 is different every time. I cannot get the same. How did u manage to get the correct code ? Thanks. Marc.

@sayanee 2 жыл бұрын

"get the same code" are you referring to the IR raw code recorded? If yes, then you are correct that the long array of numbers will not be exactly the same every time you record. I believe it's something to do in the conversion from analog IR signals to the digital form in the array. But's it's ok :) Try both the "slgihtly" different codes for the same remote control button and see! Both will still fire the same command.

Excuse me,, when i copy the code from the remot,, the code always change every i push the same button,,, so i dont know, which code i have to use,, may you help me???

No worries, you can use any one of the codes.
