Use another version of the ATTinyCore

PlatformIO IDE
1

Hello !
I’m currently working on a project using the ATTiny167, so far everything is working fine.
But I want to use another version of the ATTinyCore (version 2.0.0-dev) to test something. The current installed version is 1.5.2 in Platforms->Atmel AVR-> Packages->framework-arduino-avr-attiny.

Is there a way to install 2.0.0-dev for this one project, maybe via platformio.ini ?
I have already read something about it, but I’m still not sure…
ATTinyCore v2.0.0-dev is on Github

thanks for your help !

Fork + add package.json in avr/ folder of v2.0.0-dev branch + platform_packages + fix variant name → enjoy

[env:attiny167]
platform = atmelavr
board = attiny167
framework = arduino
platform_packages =
  framework-arduino-avr-attiny@https://github.com/maxgerhardt/ATTinyCore.git#v2.0.0-dev
board_build.variant = tinyx7

>pio run
