Rolling text

[Anders-Holst]

There is now an effect checked in to produce simple rolling text messages over your leds, "RunningText".
Previously it has been possible to do text with the app from an Iphone, but not from Android. Now you can do it with python too.

This is a simple first attempt. Only capital letters, and numbers and some punctuations, are provided. There are many potential variants of this, so see it more as a proof-of-concept and inspiration, than final solution.

You need today's release of xled_plus: pip install -U xled_plus
Then you can use it for example by starting a python prompt and typing (after replacing "HELLO" with something appropriate):

from xled_plus.samples.sample_setup import *
ctr = setup_control()
ctr.adjust_layout_aspect(1.0)
eff = RunningText(ctr, "HELLO", [hsl_color(h, 1.0, 0.0) for h in [0.1, 0.7, 0.3, 0.6, 0.8]], size=0.6, speed=0.5)
eff.launch_movie()

To make it easier to use I have now added a file "show_text.py". You can use it as:

python -m xled_plus.show_text "Your text here"

You can also add the ip-address of your device to the arguments (before or after your text) if you don't want to use "discover" to find it.
You may still have to adjust the aspect ratio though, directly in the code for now (as the argument to adjust_layout_aspect). Should be another argument I suppose...
