Add DxCore framework

[brunob45]

Basically the same thing as #18, but I changed the link to the framework to my own repo (a branch of DxCore), so everyhing is working correctly.

I made this example to test easily.

I don't want to steal @MCUdude's work, I just happened to work on the same thing, and wanted to use the framework right now. Maybe we can help eachother?

@valeros @ivankravets isn't it time to step up the game, update your toolchains and finally get proper AVR-Dx support to PlatformIO? I haven't heard from you in almost a year readring this topic. AVR-DA/DB/DD's are the latest and greatest AVRs, and it looks like Microchip is only focusing on these and the tinyAVR-2 series from now on.

DxCore has the latest toolchain with AVR-Dx support, use these binaries.

[ivankravets]

The framework package is already published in the registry https://registry.platformio.org/tools/brunob45/framework-arduino-megaavr-dxcore

Is it possible to path existing toolchain with missed files? https://registry.platformio.org/tools/platformio/toolchain-atmelavr

[MCUdude]

It is great that a community-based package can be used, but isn't it kind of important that the next generation AVRs gets added to PlatformIO with official support?

It has been a while since I looked into this, and it looks like @brunob45 did a lot more work with this PR than I did in #18.

The current toolchain needs to be patched or updated. I'm not sure where he keeps the sources, but I know @SpenceKonde's toolchain works (used with the DxCore boards manager install) on all platforms and supports all current AVR DA and DB series. It's just the Arduino toolchain with a (few?) additional Microchips packs applied.

Hi all,

First, thanks for acknowledging my work.

@ivankravets The package was also published in the registry by someone at platformio : https://registry.platformio.org/tools/platformio/framework-arduino-megaavr-dxcore but it is outdated. Any idea why there hasn't been any update for more than a year?

The way I patch atmel's toolchain is with a python script, callable from inside a pio project as pio run -t fixtoolchain. This script will

• fetch the latest AVR Dx pack from atmel's website,
• install the missing files in the previoulsy installed toolchain and
• generate the .json board definition files so the new chips can be used by platformio.

As you can see, all the examples compile fine in the github workflow.

To make things even better, I'd like to know if there is a way to run a python script automatically right after installing a package. That way, I could execute the patching script without the need for the user's manual intervention.

Or even better, we should use a toolchain that is up to date. Maybe SpenceKonde has the answer on this one.

I've said like a million times, y'all are welcome to use the toolchain packages that I supply for DxCore.... And as new parts come out, I update it, so every time there is a significant change that impacts megaTinyCore or DxCore, I make a new version of the toolchain package (using the latest atmega, attiny, dx-series and automotive AVR ATpacks), and it shows up in m board manager json.. I haven't had to do that in quite a while now - The current versions are

The files that you need only rehost somewhere and use are thus: https://spencekondetoolchains.s3.amazonaws.com/avr-gcc-7.3.0-atmel3.6.1-azduino4b-i686-w64-mingw32.tar.bz2 https://spencekondetoolchains.s3.amazonaws.com/avr-gcc-7.3.0-atmel3.6.1-azduino4a-aarch64-pc-linux-gnu.tar.bz2 https://spencekondetoolchains.s3.amazonaws.com/avr-gcc-7.3.0-atmel3.6.1-azduino4a-arm-linux-gnueabihf.tar.bz2 https://spencekondetoolchains.s3.amazonaws.com/avr-gcc-7.3.0-atmel3.6.1-azduino4a-i686-pc-linux-gnu.tar.bz2 https://spencekondetoolchains.s3.amazonaws.com/avr-gcc-7.3.0-atmel3.6.1-azduino4a-x86_64-apple-darwin14.tar.bz2 https://github.com/SpenceKonde/DxCore/releases/download/1.3.4/avr-gcc-7.3.0-atmel3.6.1-azduino4a-x86_64-pc-linux-gnu.tar.bz2 (the x64 linux i hosted on github because 99% of it's extremely heavy use is from the automated CI tests - it's to githiub's distinct advantage to keep it within their network as I understand it.

[brunob45]

I don't know what's needed to host files, but is there a reason why we can't host all the toolchains as part of Github releases, just like your version for x86 Linux?

All I could find is that individual files must be under 2GB, and there are no download quota... https://docs.github.com/en/repositories/releasing-projects-on-github/about-releases#storage-and-bandwidth-quotas

Sorry if I missed something obvious...

[valeros]

Thanks @brunob45 for the PR, merged with slight modifications according to the latest changes in DxCore v1.4.5.

[LaurentR59]

Hello

Any idea for a date with latest DXCore versions supporting AVR_DD parts?
