Support for DX CORE CPU and MightyCORE CPU possible?

[LaurentR59]

Is your feature request related to a problem? Please describe.

As alter part AVR DA DB DD and modern ATtiny CPU are interesting to use
DX CORE is closed to MEGACOREX.

Describe the solution you'd like

Support generic timer mode like ATMEGA4809 CPU for new CPU (ATTINY series 0 1 () 2 and AVR DA DB (DD?)

Describe alternatives you've considered

none existing or adjustment for supporting new parts

Additional context

Put a look at DX CORE lib and mithtycore from Spence Konde.

Thanks in advan,ce t consider benefits of enlargment copatibility CPU supported.

Regards
Laurent

Hi @LaurentR59

Thanks for the info and request. I'll have a look and try when having time, which is hard for me to reserve and find. So I can't promise now.

I already install the DxCore and megaTinyCore core

BTW, how and where can I find and buy the eval boards / products, working with Arduino IDE, to test ? I'd appreciate if you or anybody can donate the boards / system to test.

Regards,

Hello

Probably best test cards for tests are respectively the curiosity nano XXX boards.

Cards are supported by libraries and IDE tools. (like platformio or arduino IDE)

For DX CORE AVR DA DB, the curiosity nano avr128da48 and 128db48 from microchip are available for exemple at MOUSER. ( but on some others dealers too or directly from Microchip)

About Attiny probably it should be this one with ATTINY3217 CPU:

I have only one of them the curisoity nano128DA48 and made a breadbord with ATTINY1606 (but require UPDI programmer) so may it help?

Thanks for your time on such futur lib update.

Thanks for the info.

I've already ordered those boards and will have a look when they arrive

I made a error on mightycore label It should be more megaTinyCore from Spece Konde too like DX CORE.

Sorry for mistake anyway.
Should be a good step to get them!

Too late.

I almost finish creating the first ATmega_TimerInterrupt library for MightyCore.
Will publish within hours.

If you have board, please test and report as I'm dry-coding, without any ATmega???4 board.

I'm closing the issue now as done.

Those libraries will be merged into this library after sometime on actual real-case tests to be mature enough.
