ScrollDisp
v0.7.0
An example of an unicornhat hack for Launchpad Mini or Bhoreal.
This is a custom version of scrolldisp.py that display text on unicornhat
with use of bhorunicornhat to use with a Bhoreal or a Launchpad mini mk2
Default device is the launchpad.
Command line to display 2 chars:
To display 'OK' :
python3 scrolldisp.py OK
To display a rainbow :
python3 scrolldisp.py ~R
See the end of this script for more option like scrolling or use a bhoreal in command line.
As a Library :
Display(text, color=(255,255,255), delay=0.2, mididest ='launchpad')
DisplayScroll(text, color=(255,255,255), delay=0.2, mididest = 'launchpad')
Remember there is Cls functions
launchpad.Cls()
bhoreal.Cls()
