The commands below should be used in a Bash-like shell
The trigger_cal binary is used to retrieve library files used by this code. This binary can be found at /usr/bin/trigger_cal.
Since the binary was made with PyInstaller, it can be extracted with pyinstxtractor. This happens as part of a Docker image build process.
Install a recent version of Docker and then run:
docker build --progress=plain -t=steam_deck_overwrite_trigger_cal .
To explore files extracted from the trigger_cal binary, start a shell in a container built from the image created in the previous step:
docker run --rm -it steam_deck_overwrite_trigger_cal sh
And then navigate to the /home/trigger_cal_extracted directory.
Here you can use decompyle3 or uncompyle6 to decompile the pyc files if needed for reference
Since the code reads from and writes to the trigger HID, the only way to test things is to pack it into a binary using the next step, and run it on the Steam Deck
If you use any shell that uses MinGW (such as Git Bash), first run export MSYS_NO_PATHCONV=1.
To build the binary, run: docker run --rm -it -v $(pwd)/src/overwrite_trigger_cal.py:/app/overwrite_trigger_cal.py -v $(pwd)/dist:/app/dist steam_deck_overwrite_trigger_cal
Built binary is now ready at dist/overwrite_trigger_cal
Tip: Map the dist folder in the Docker container directly into an SMB share to easily access it on the Steam Deck, e.g.:
docker run --rm -it -v $(pwd)/src/overwrite_trigger_cal.py:/app/overwrite_trigger_cal.py -v /c/shared:/app/dist overwrite_trigger_cal
