`clean.py` doesn't work on Inky pHAT no matter what you do #118

Closed raspberrycoulis closed 3 years ago

raspberrycoulis commented 3 years ago

I believe I have an early model Inky pHAT (Yellow), but trying to run the clean.py example to clear my screen does not work, no matter what I try.

Running ./clean.py -t phat -c yellow results in:

Inky pHAT: Clean

Displays solid blocks of red, black, and white to clean the Inky pHAT
display of any ghosting.

Failed to detect an Inky board, you must specify the type and colour manually.

usage: clean.py [-h] [--number NUMBER]
clean.py: error: unrecognized arguments: -t phat -c yellow

Based on the above, it looks like the argument -n x is required, so tried again with ./clean.py -t phat -c yellow -n 1 but get the exact same error message.

However, running other examples - such as name-badge.py with the same -t phat -c yellow works just fine, but the script still complains:

Inky pHAT/wHAT: Hello... my name is:

Use Inky pHAT/wHAT as a personalised name badge!

Failed to detect an Inky board, you must specify the type and colour manually.

There are also many installation issues when running curl https://get.pimoroni.com/inky | bash, such as:

This script will install everything needed to use
Inky pHAT & wHAT

Always be careful when running scripts and commands copied
from the internet. Ensure they are from a trusted source.

If you want to see what this script does before running it,
you should run: 'curl https://get.pimoroni.com/inky'

Finalising Install...

Some packages could not be installed, review the output for details!

This is on a fresh installation of Raspberry Pi OS Lite on 19 July 2021, running on a Raspberry Pi Zero W. Python 3 version 3.7.3 and Python 2 version 2.7.16 if that helps at all.

The install issues are normal, we prefer apt packages where available and fall back to pypi- this ends up being a bit noisy, eg:

As for clean.py it looks like parse_args needs to change to parse_known_args on this line: https://github.com/pimoroni/inky/blob/e073c8e5d1bffa27f370c0c6ae1ecccabb62a366/examples/clean.py#L22

That's a bug!

Edit: or, more specifically, it should be:

args, _ = parser.parse_known_args()

Just adding - I have changed the line mentioned above and this now works as expected.
