I have added watchdog.h from libraries.
This is how platformio.ini looks :
[env:ATmega328P]
platform = atmelavr
board = ATmega328P
framework = arduino
lib_deps =
nadavmatalon/WatchDog@^1.2.0
It is showing error like this
I think the library.json is poorly written becauase there is no framework called “AVR”. It’s framework = arduino. The platform is atmelavr. So AVR is any case just wrong.
You might be able to convince the LDF to include the library if you disable its sanity checks per docs:
lib_compat_mode = off
in the platformio.ini.
