# v0.1, 2019-03-05, jw initial draught. HID code is much simpler than expected.
# v0.2, 2019-03-07, jw support for loading bitmaps added.
# v0.3 jw option -p to preload graphics for inline use in text.
# v0.4, 2019-03-08, jw Warning about unused images added. Examples added to the README.
# v0.5, jw Deprecated -p and CTRL-characters. We now use embedding within colons(:)
# Added builtin icons and -l to list them.
# v0.6, 2019-03-14, jw Added --mode-help with hints and example for making animations.
# Options -b --blink, -a --ants added. Removed -p from usage.
# v0.7, 2019-05-20, jw Support pyhidapi, fallback to usb.core. Added python2 compatibility.
# v0.8, 2019-05-23, jw Support usb.core on windows via libusb-win32
# v0.9, 2019-07-17, jw Support 48x12 configuration too.
# v0.10, 2019-09-09, jw Support for loading monochrome images. Typos fixed.
# v0.11, 2019-09-29, jw New option --brightness added.
# v0.12, 2019-12-27, jw hint at pip3 -- as discussed in https://github.com/jnweiger/led-name-badge-ls32/issues/19
# v0.13, 2023-11-14, bs modularization.
# Some comments about this big change:
# * I wanted to keep this one-python-file-for-complete-command-line-usage, but also needed to introduce importable
# classes for writing own content to the device (my upcoming GUI editor). Therefore, the file was renamed to an
# importable python file, and forwarding python files are introduced with the old file names for full
# compatibility.
# * A bit of code rearranging and cleanup was necessary for that goal, but I hope the original parts are still
# recognizable, as I tried to keep all this refactoring as less, as possible and sense-making, but did not do
# the full clean-codish refactoring. Keeping the classes in one file is part of that refactoring-omittance.
# * There is some initialization code executed in the classes not needed, if not imported. This is nagging me
# somehow, but it is acceptable, as we do not need to save every processor cycle, here :)
# * Have fun!
# v0.14, 2024-06-02, bs preparation for automatic or manual endpoint and bluetooth.

-m 5 "Animation"
Animation frames are 6 character (or 48px) wide. Upload an animation of
N frames as one image N*48 pixels wide, 11 pixels high.
Frames run from left to right and repeat endless.
Speeds [1..8] result in ca. [1.2 1.3 2.0 2.4 2.8 4.5 7.5 15] fps.
Example of a slowly beating heart:
sudo %s -s1 -m5 " :heart2: :HEART2:"
-m 9 "Smooth"
-m 10 "Rotate"
These modes are mentioned in the BMP Badge software.
Text is shown static, or sometimes (longer texts?) not shown at all.
One significant difference is: The text of the first message stays visible after
upload, even if the USB cable remains connected.
(No "rotation" or "smoothing"(?) effect can be expected, though)
