Pin-id scanner options

The options of the pin-id host scanner host/identify_pmod_pins.py. The options are run from designs/pmod-pin-id on the Raspberry Pi. How to run a whole scan is on How to scan an Arty A7’s wiring with the pin-id design.

The Option column is the flag, the Command column is a full command that uses it, and What it does is the effect.

Option	Command	What it does
none	uv run python host/identify_pmod_pins.py	Scans all PMOD HAT GPIOs (the default)
--gpios	uv run python host/identify_pmod_pins.py --gpios 8 19 21	Scans the listed GPIOs
--hat-port	uv run python host/identify_pmod_pins.py --hat-port JA	Scans a single HAT port
--no-unload	uv run python host/identify_pmod_pins.py --no-unload	Skips kernel module unloading, for when it is already done
