MRAB, thank you for teaching me proper Python syntax for how I tried to
use the or operator.
Dennis, I must have learned allot recently as I believe I understood 99%
of that code. I see how it is not just more advanced, but actually better
than what I had. However, line 47 (cumTime[colour] += now - changeTime)
had an error I could not figure out what to do about. Considering my time
line I decided not to leave it to latter. Will be using these electronic
flags at next year's game and for then I intend to just be better about
everything. Will use your code to learn to get there.
Hakugin, thank you you as well. I took the basic ideas you showed me for
improvement and used them. The pulse settings variable was not liked by
the interpreter, so I simplified it. I turned it into a hex value for
each button press, then in the main loop I inserted the whole line for
the LED pulse command, but put "pulse_settings" after "hex=" in the
arguments. This worked.
I added a few green blinks of the LED to indicate the starting and
stopping of the script. Also, I got the log files score print outs upon
exit working. Very important, and also importantly, I have it so it stops
after a certain amount of time. For testing, I have it at 60 seconds, but
games will be 3600 seconds on average when really being used.
The stopping after a certain amount of time was done in a way that
apparently technically works, but seems very weird and probably wrong to
me. You may freak out when you see it. I used an else statement inside a
while loop and it just feels so strange. At least it works.
Hoping I might be able to make it so I boot the Pi, it loads the script,
script waits for the user to tell it how long to make a game, game
starts, scripts ends game at appropriate time, saves dated log file with
scores, then waits for user to enter new game length to start new game.
This is probably way to much to hope to accomplish in time. For next year
for sure though. It would be better for the referees to operate that way.
Next I will try and integrate wireless communications. If anyone here
knows Synapse RF modules well, or at all, PLEASE contact me.
Here is the code I did up most recently. Again, thanks for all the
suggestions, code examples, and general help.
