I'm probably just misunderstanding, but when I enter:
pcf.port = [False, False, False, False, True, True, True, True] I would expect the four least significant bits to be low, and the highest four significant bits to be high. I'm getting the opposite. I've tried to reverse the list, but that doesn't seem to work either. What am I misunderstanding?
Thanks very much,
Leonard Gabrielson
First of all thanks for an awesome library!
The problem I have is that after some amount of calls to the api of the library I get this error:
[2018-02-23 11:58:18 +0000] [2093] [ERROR] Socket error processing request.
