I am trying to make a project using STM8S105K4T6 and NEC based IR remote. I am using Sduino to program the board. I want to turn on and off two relays and two leds using IR remote. Please help me to make the IR decoder for the board.

Welcome @RV97, to the community!

It seems you are looking for a solution for your entire project, and for a very old MCU at that, for which you will probably find little support in a forum. However, you can divide the project into sub-projects and think about each one.

If it's just about the IR decoder, your favourite search engine will probably help you with a search for e.g. ‘+infrared +nec +stm8 +decode’. However, I don't hold out much hope for a finished example, because most developers prefer to work with more modern 32-bit MCUs than with outdated 8-bit MCUs.

Thank you very much for your response sir.

Kindly can you please suggest me some modern 32-bit MCU for this project?

My objective is to use NEC protocol based remote control two control two relays & 2 leds, I will also use 2 manual tactile switches in this project. I will also implement a 2 digit 7 segment common anode display after successfully testing this setup.

So kindly suggest me a good microcontroller that can be used in this project efficiently.  

Thank you.

There are several thousand different order numbers of STM32, essentially any of them can be used for your application.

The NUCLEO boards are not using counterfeits/clones like the so-called Bluepills and therefore work reliably. They also come with a free ST-LINK/V2-1 debugger, which can (mostly) also be used for debugging or programming other STM32 targets, e.g. one of them:

And then use ‘+infrared +nec +stm32 +decode’ to search for possible solutions and ideas and take your time to look at them. Please also read the documentation for the chips (data sheet and reference manual). For the boards mentioned above you'll find the documentation at:

Good luck!
