How about support for the ATtiny x14/x17/x18 series?
I'm keen to see support added for these very capable chips, particularly the attiny1617 and attiny817
Is there any chance of integrating the excellent megaTinyCore from @SpenceKonde?https://github.com/SpenceKonde/megaTinyCore
I would love to see my cores (megaTibyCore and ATTinyCore) supported by PlatformIO, however I'm not familiar with it (I just use the arduino IDE). What can I do to help this happen?

@SpenceKonde ATTinyCore is already included in PlatformIO, it seems, though it looks like it the somewhat old 1.2.2 version.
As I understand it, adding megaTinyCore would require it to be included in framework-arduinoavr, which lives here: https://github.com/platformio/platformio-pkg-framework-arduinoavr. ATTinyCore is already there under the core[tiny|tinymodern] cores. I believe it would also require making some changes adding a new boards_megatinycore.txt with board definitions that can be exposed to developers. Did I miss anything, @ivankravets?
Oh god, 1.2.2? Yeah, we should try to get ATTinyCore bumped up to 1.3.2 - I've changed and improved a lot since then....
Quite frankly, I know very little about PlatformIO, other than that people keep complaining that my core isn't supported there, or that bugs I fixed eons ago in ATTinyCore are still present there. I don't remember who set up ATTinyCore 1.2.2 on PlatformIO, but I know it wasn't me.
@SpenceKonde looking at the commit, @ivankravets was the last one to update the ATTinyCore in PIO. I can take a look at making that update over in the framework repo and submit a PR to get it moved up to 1.3.2.
Ok, I’ve made the pull request, following the pattern of the last update and using ATTinyCore 1.3.2 as the basis. @ivankravets can you point me to the best way to advise folks to test the PR with those updates?
Thanks for your PR! Everything is merged and deployed. Please re-test with upstream version of dev/platform http://docs.platformio.org/en/latest/platforms/atmelavr.html#upstream
As for the megaTinyCore, @stonehippo you can do similar PR. I would like to ask to use a new board ID notation. We plan to add soon support for starting a project from bare MCU/Device and from Development Kits. Dev/kits can have own name but device ID should have official IF provided by the vendor. Mostly, they are uppercased. For example, instead of attiny817.json we should use ATtiny817.json => https://www.microchip.com/wwwproducts/en/ATTINY817
Thanks for merging the PR, @ivankravets. I’ll do another for #160 as soon as I get a chance. Will also look at the new board ID notation, too.
@SpenceKonde @ivankravets I’m looking at bringing megaTinyCore over, but I noticed a couple of things that lead to some questions that might need to be addressed before the BSP will work on PlatformIO:
- @SpenceKonde I noticed in your release notes that prior to release 1.0.1, the official Arduino megaAVR BSP needed to be installed to get compiler support, but that changed with 1.0.2+. Can you give me a hint on why that is (e.g. do you now get the compiler installed alongside megeTinyCore automatically?)
- Also, it looks like upload/flashing gets done via UDPI rather than ISP?
- @ivankravets if I needed to get the megaAVR compiler installed as a dependency for these MCUs/megaTinyCore, I assume we’d need a new toolchain deployed (e.g.
toolchain-atmelmegaavr) up on sourceware?
Based on all of this, I’m wondering if it doesn’t make more sense to create a new platformio-atmelmegaavr repo if the tools architecture are that different.
Also, it looks like upload/flashing gets done via UDPI rather than ISP?
Yes this series of AVRs requires UPDI and has no support for ISP.
Thanks, @JonSilver. Looks like I can build a UPDI programmer from one of the Pro Mini’s I have laying around.
I’m going to have to get a couple of these new MCUs so I can test anything I do. ~~Have you got the breakouts for this up on Tindie, @SpenceKonde?~~ I’m also going to get an Arduino Nano Every or Uno WiFi rev2, since they also use the newer megaAVR arch.
Ok, got a couple of boards from @SpenceKonde. I’ll pick this up again when they arrive, I guess.
@ivankravets FYI I tested the upstream update for ATTinyCore with an ATtiny85 and things are looking good with 4.2.0.
megaTinyCore (and the other megaavr parts) requires 7.3.0 of the compiler; the recent versions of ATTinyCore handle this when installed via board manager (but not when installed manually - I'm not quite sure how to do that in a graceful way). I'm not sure how such custom tools are handled in platform IO - you can see the packages that get installed in the board manager json https://github.com/SpenceKonde/ReleaseScripts/blob/master/package_drazzy.com_index.json
Got the boards today (thanks, @SpenceKonde!). This next week is nuts, so I’ll most likely start to work on the megaTinyCore support next week.
Hi Guys, any news on this? I am also interested in the new ATTinys but would love to keep on working with platformIO! Cheers, Stif
Hi @stif, I've been wrapped in some other work, but have been planning to get back to adding megaTinyCore. I'll take a whack at it this weekend.
Ditto from me. I guess I'll be in the ArduinoIDE for the moment... (and wrecking my nice folder structure).
Ha! Workaround (for the yuck folder structure thing): added a folder in my repo for the Arduino IDE and symbolic-linked the main.cpp to the folder name .ino, as well as linking the "include" files. Doesn't work for all, but it's a simple project.
Quick update: I’m working through adding the board definitions, and will need to make sure the right versions of AVRDUDE and the compiler are available. Will also need to confirm UPDI with pio run -t upload. Probably won’t have it all ready for a PR this weekend, but within the next few days.🤞🏾
Hey that’s awesome. Thanks for the effort!

Just as an FYI (which may be unwelcome), 2.0.1 is basically out (it's in the github now) and like, there are a bunch of things different in it that might be relevant to this effort - basically it's a release to fix all the bad architecture decisions I made before, before things got any more widely deployed than they already were
@stonehippo thanks for all your work on this. I'm transitioning to pio from Arduino IDE now and asked @SpenceKonde if he had any appetite to support pio. He pointed me here and after reading back through the issue, googling around pio community and looking at issues related to @MCUdude's MiniCore, MegaCore and MightyCore + documentation on setting fuses, I'm none-the-wiser about a) has support for megaTinyCore been added and b) is there an efficient way of importing necessary files without having to handwrite the platformio.ini for every combination of IC and fuse setting? Thanks for anyone who can enlighten me.
@SimonMerrett short answer is that I got pulled into a bunch of other stuff and haven't had time to finish integrating MegaTinyCore into PIO yet. Good news is I'm taking a few days off, so I hope to get to it this week.
Thanks @stonehippo , hopefully I'll have worked out how to use pio a bit better by then.
@stonehippo is there any community contribution that could help with the megaTinyCore integration?
