v 0.1
|

A termeal version with led strip on raspberry pi
|
||||
|
||||
|
||||
sniff packets from interface en0 using python module scapy (2.3.1)
|
||||
generate led color for bhoreal in usb midi mode depending on packet port number
|
||||
send led number + color to PD patch boreal.pd
|
||||
in OSC format : /bhoreal/in lednumber ledcolor
|
||||
color is midi parameter so 0 to 127.
