I'm a beginner so sorry for the dumb things I might say or ask.
So I bought an attiny11 for a small toy I want to build. I honestly bought it because it was the cheapest and I really don't need that much memory for my code anyways.
As I understand it, I have to download some additional files called "cores" to my arduino IDE. However, I've been unable to find anything for attiny11 so I'm beginning to wonder if it's even possible.
If it's possible and you are willing to help, please leave a reply. Thanks in advance
Afaik nobody has made a core for the attiny11. 1k of flash is really hard to do much with using arduino functions - that's why I had no interest in adding support for it to my core.
From the Datasheet it seems it is very old device. It has no RAM, narrow voltage range, it is slow, no PWM, no ADC (only analog comparator), no ISP (probably programmed by high voltage only!). I think current "lovest level" ATTiny is ATTiny13A - quite cheap on eBay and much more powerful.
Where did you manage to get an ATtiny11? AFAIK, they got discontinued shortly after Atmel's "fire-sale" ($0.25 each!) back around 2004, and disappeared from most distributors shortly after that. In addition to not having any RAM, they require an uncommon device programmer (one that does "high voltage serial programming.")
Pre-arduino, there was net-organized group buy of the things that I participated in (I still have a bunch of chips!), but I've avoided even working with them because ... you can't even get more of them. throwing them away and getting ATtiny13s or ATtiny841s is your best bet unless you want to get really adventuresome (build your own programmer, write in assembler, etc...)

Thanks for making things clear. I just switched for another more capable attiny.
I managed to get that attiny11 from an old electronics shop for about 1$ and I thought I might use it for something.
