У нас есть Hasseb USB Dali Master и мы пытаемся использовать библиотеку python (github.com/sde1000/python-dali). Но коды из раздела «Примеры» не работают.
Мы использовали Armbian Linux (операционная система на основе Ubuntu)
Библиотека https://github.com/onitake/daliserver установлена.
Мы пытаемся запустить set_single.py отдельно.
$sudo python set_single.py
Traceback (most recent call last):
File "set_single.py", line 25, in <module> d.send(cmd)
File "build/bdist.linux-armv7l/egg/dali/driver/daliserver.py", line 43, in send
File "/usr/lib/python2.7/socket.py", line 575, in create_connection raise err
socket.error: [Errno 111] Connection refused
И попробуйте запустить dalliserver в другом терминале.
$ sudo python server.py
('Connection address_:', ('127.0.0.1', 43653))
Traceback (most recent call last):
