## Warning

This one uses a USB-HID interface, while others use USB-Serial (see references below).
## Command Line Installation and Usage
### User access to badge on all Linuxes
The following will install a udev rule allowing anybody read/write
access to the badge via USB.
sudo cp 99-led-badge-44x11.rules /etc/udev/rules.d/
sudo udevadm control --reload-rules && sudo udevadm trigger
### Required dependencies on Arch Linux
sudo pacman -Syu python-pyusb python-hidapi
### Required dependencies on Debian/Ubuntu Systems
sudo pip install pyhidapi
sudo pip install pillow
sudo apt-get install libhidapi-hidraw0
sudo ln -s /usr/lib/x86_64-linux-gnu/libhidapi-hidraw.so.0 /usr/local/lib/
or
#### Using Debian/Ubuntu packages (recommended):
sudo apt install python3-usb python3-pil
#### manually using a python virtual environment
Using a venv will allow to use pip to install dependencies without the danger
that the installed modules will interfere with the system installed ones.
sudo apt install python3-venv
python3 -m venv ledtag
source ledtag/bin/activate
pip install pyhidapi pyusb pillow
# this should now work:
# python3 led-badge-11x44.py -m 6 -s 8 "Hello" "World!"
if the udev rules are installed, you should be able to access the badge without sudo / root privileges.
To reuse the venv again at a later point:
source ledtag/bin/activate
python3 led-badge-11x44.py …

There are some options defining the default type:
- use lednamebadge.py directly: default type is 11x44
- rename lednamebadge.py to something with '12' and use that: default type is 12x48
- use led-badge-11x44.py: default type is 11x44
- use led-badge-12x48.py: default type is 12x48
For all these options you can override the default type with -t
### Animations
See the gfx/starfield folder for examples. An animation of N frames is provided as an image N*48 pixels wide, for both 48 and 44 pixel wide devices.
## Usage as module
### Writing to the device
You can use lednamebadge.py as a module in your own content creation code for writing your generated scenes to the device.
- create the header
- append your own content
- write to device
The method `header()` takes a number of parameters:
- up to 8 lengths as a tuple of numbers
- each length is the number of byte-columns for the corresponding bitmap data, that is the number of bytes of the
corresponding bitmap data divided by 11 (for the 11x44 devices) respective 12 (for the 12x48-devices), where one
byte is 8 pixels wide.
- arguments comparable to the command line arguments: up to 8 speeds, modes, blink-flags, ants-flags each as tuple of
numbers, and an (optional) brightness as number.
- Optionally, you can give a timestamp as datetime. It is written to the device as part of the header, but not visible
at the devices display.
Your own content has to be a byte array with the bitmap data for all scenes. Of course, it has to fit the given lengths.
See the following graphic for better understanding:
![bitmap_data_onebyte.png](photos%2Fbitmap_data_onebyte.png)
![bitmap_data_onescene.png](photos%2Fbitmap_data_onescene.png)
For a 12x48 device there have to be 12 bytes for each byte-column instead of 11, of course.
![bitmap_data_all.png](photos%2Fbitmap_data_all.png)
Example:
Let's say, you have 2 scenes, one is 11x32 pixels, one is 11x60 pixels. So, the first have 4 byte-columns and 44 bytes,
the second has to be padded with 4 empty bit-columns in the last byte-column to 11x64 pixels and has therefore
8 byte-columns and 88 bytes.
We like to display both in mode 4, the first one with speed 3 and the second one with speed 2 and the second one shall
be displayed with ants. And we like to set the initial brightness to 50%.
This would be achieved by these calls:
```python
from lednamebadge import LedNameBadge
buf = array('B')
buf.extend(LedNameBadge.header((4, 8), (3, 2), (4,), (0,), (0,1), 50))
buf.extend(scene_one_bytes)
buf.extend(scene_two_bytes)
LedNameBadge.write(buf)
```
### Using the text generation
You can also use the text/icon/graphic generation of this module to get the corresponding byte buffers.
This is quite simple and just like with the command line usage. There is the additional option to create a bitmap just
and only from an image file by giving the filename instead of a message.
```python
from lednamebadge import SimpleTextAndIcons
creator = SimpleTextAndIcons()
scene_a_bitmap = creator.bitmap("Hello :HEART2: World!")
scene_b_bitmap = creator.bitmap("As you :gfx/bicycle3.png: like...")
scene_c_bitmap = creator.bitmap("gfx/starfield/starfield_020.png")
```
The resulting bitmaps are tuples with the byte array and the length each. These lengths can be used in header() directly
and the byte arrays can be concatenated to the header. Examle:
```python
from lednamebadge import *
creator = SimpleTextAndIcons()
scene_x_bitmap = creator.bitmap("Hello :HEART2: World!")
scene_y_bitmap = creator.bitmap("Complete example ahead.")
your_own_stuff = create_own_bitmap_data()
lengths = (scene_x_bitmap[1], scene_y_bitmap[1], your_own_stuff.len)
buf = array('B')
buf.extend(LedNameBadge.header(lengths, (3,), (0,), (0,1,0), (0,0,1), 100))
buf.extend(scene_x_bitmap[0])
buf.extend(scene_y_bitmap[0])
buf.extend(your_own_stuff.bytes)
LedNameBadge.write(buf)
```
## Development
### Generating Plantuml graphics
You will need PlantUML and potentially GraphViz dot to generate the diagrams from the *.puml files.
Just run `plantuml "*.puml"` from the `photos` directory to regenerate all diagrams.
### Running the unit tests
Run `python run_tests.py` from the `tests` directory.

-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)

# 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!

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)
