Hey! ✋
This PR introduces a minimal Nix shell to setup the build environment needed by this project. This is especially useful for NixOS users, as it avoids issues caused by pip trying to install some dependencies (namely
google) into the read-only Nix store. Instead, both PlatformIO and Python are set to store data locally under.platformioand.python313, respectively.I tested this by entering the shell (via direnv) on my system without neither PlatformIO nor Python globally installed, and running
pio run -e heltec-v3succesfully.For the record, I might have missed some implicit dependencies that weren't needed to build the firmware of my device, but those can be easily added later if someone else runs into issues related to that.
