Hello! Please help me, I have no idea how to install attinycore by spencekonde, their server seems to be down, I tried some github/sourceforge installs but I never sucseeded and kept getting errors, chatgpt couldn't help me as well. I am using arduino uno R3 as ISP for Attiny85. I need exactly attinycore by spencekonde because I need to turn on B.O.D which I cant do with other cores. Any help is apreciated, any other method is appreciated, ask questions, I will try to do what u say from blank list. Thanks yall for help :heart:

Have you followed these instructions?

3

You are right. I just tried it and it failed.

Version 1.4.1 works, must be something wrong with 1.5.x

4

1.4.1 IDE works or 1.4.1 ATTinyCore?

5

1.4.1 Attiny Core but the manual download does work, just tried it.
Not sure if you want to try the new version 2.0.0

6

Try this workaround.

7

Did not work for me. Still can't download any version greater than 1.4.1
There are apperently no download manager packages for versions 1.5.n

8

Bummer, does not work for me anymore, but with a different error than yous.

I can select 1.5.2 , but then it fails on downloading the micronucleus tools as they need to come from the azduino.com server which is not working.

So the workaround needs another workaround.

I'm not sure that I would want to use a version higher than 1.4.1 for now and definitely not version 2.0.0. 1.5.2 was a fix for 1.5.0 and there was no 1.5.1. The documentation for it did not make it sound very stable

11

I could get it to work only by doing the manual installation of 1.5.2

Unpacking the zipfile in a “hardware” folder within my sketchbook folder.

You will not have the micronucleus (USB) drivers then, but you can install them separately afterwards, should you need them. I pulled them from the internet archive.

If you have AVR Programmer, you can use that to configure the BOD fuses. After that you may follow the procedures of the attached file to program the ATtiny85 using Arduino as ISP Programmer.

Can you upload code?

I think it's best to stick with 1.4.1 for now.

14

I believe the workaround described here will still work:

Those are Windows-specific. If you are using a different operating system, let me know and I'll provide adjusted instructions for your system.

The one linked to in #6 was addressing a similar, but different defect.

15

Is there a way to tell if the core is essentially abandoned permanently, such as by Spence Konde not being available or able any more and other contributors not having enough access to the GitHub project to make repairs or take the project on? What would happen to the core and support for it?

16

You can look around the GitHub repository to check for activity from SpenceKonde.

A quick way to check for signs of life is on the GitHub profile page:

https://github.com/SpenceKonde

However, that doesn't tell the full story, because only certain actions appear on the profile. For example you won't see any indication there if Spence commented on a bug report, discussion, or pull request. And you also wouldn't see any indicator if Spence fixed the actual problem, since the problem is with their external website which is not associated with a GitHub repository.

I'm confident that Spence will eventually fix the problem. However, we see a clear pattern of this happening over and over again. The community has offered solutions that would not require Spence to maintain a website, but that was rejected.

Everyone is welcome to fork this open source software. That is usually something to be avoided if possible, because it can result in fragmentation into multiple projects which each receive less attention than a single canonical project does.

There is actually already an actively maintained fork, which has the problem solved. And as a bonus, it even has added support for the Arduino IDE sketch debugger (or any other debugger you like):

https://github.com/SpenceKonde/ATTinyCore/issues/913#issuecomment-3708562207

I am working on integrating debugging into ATTinyCore (v1.5.2) and have, for this reason, set up a fork that everybody can use. I also retrieved the micronucleus uploader executables from the Wayback Machine, so that one can now download everything from the fork as long as the outage lasts.

Add https://downloads.pyavrocd.io/package_debug_enabled_index.json to the list of Additional Boards Manager URLs in the Preferences dialog. After that, you can install the board package ATTinyCore (Debug enabled). This core is identical to ATTinyCore v1.5.2, save for a few more tools and entries in platform.txt, boards.txt, and programmer.txt. If you do not touch the entry Optimize for Debugging, there is actually no observable difference.

Thank you everyone for help, I was somehow able to accidentally install ATTinyCore by SpenceKonde 1.5.2 (with this link: http://drazzy.com/package_drazzy.com_index.json) on Arduino IDE 2.3.8

I was meant to try 1.4.1 but somehow this newer one installed.

I have no idea why it worked but it just did

18

Do you have any reference to this link? It looks like the one included in the pdf file of #12.

19

Post #2 from Jim-P is where I took it

20

Yes! @Jim-P's reference and mine one are the same.

I'm using linux mint
