Projector is a personal tool I user to control my Panasonic PT-RW330 projector and Extron IN1604 DTP scalar over serial using a Raspberry Pi.
Building the project can be done using poetry.
$ poetry build
$ pip install .
Make sure the user is a member of the dialout
group.
Wake projector and scaler and select input 2:
$ projectorpi 2
Put projector and scalar in sleep mode:
$ projectorpi --sleep
