subwayclock's Issues

Can't use 2 different station feeds in one instance...

If I try to use 2 different stations not on the same feed, the output fails. Example below.

pi@raspberrypi:~/subway $ ./mta.py 234N A42N
(('2', '4', '4', '2', '4', '2', '4', '2', '4'), (4, 6, 15, 19, 22, 31, 39, 42, 54), [], [])

pi@raspberrypi:~/subway $ ./mta.py 234N 234S
(('2', '4', '4', '2', '4', '2', '4', '2', '2'), (3, 5, 14, 19, 22, 30, 39, 42, 54), ('2', '4', '4', '2', '2', '4', '4', '2', '4', '2', '4', '2', '4', '2', '2', '4', '2'), (7, 8, 17, 21, 30, 31, 34, 37, 46, 52, 58, 64, 71, 77, 91, 92, 107))

I think you may end up having to make 2 calls if there are different feeds for the 2 stations called.

I was using it for 2 nearby stations in Brooklyn headed into the city. One is Hoyt-Schermerhorn, on the A, C, G (A42N) and Nevins Street on the 2,3,4,5 (234N).

Thank you for your awesome code. It's working in ALL other aspects. 👍

API Change

I noticed that my clock started having problems a little while back but was able to get it working again with a reboot. Recently i attempted this and when it came back up it couldnt connect at all. I attempted to build a new unit to see if something had gotten corrupted but discovered the issue appears to be with the API/mta.py. I noticed that my account no longer let me sign in so i signed up again and when i did so, I tried to run mta.py manually and it returned blank values. I tried to get a new api key and it returns the erros listed below. I was wondering if you had encountered the same thing and if you had modified the script accordingly. It appears the issues stems from the get train times function.

subway.py not working tkinter import *

Im getting an error

ModuleNotFoundError: No module named 'tkinter". I have no idea how to address this.

I will state that i am doing this in an Ubuntu VM because my new PI and Display dont arrive until next week but i wanted to get everything working first so that this would be an easy build to give to my girlfriend as a gift.

When i run ./mta.py with my station information i get good results so that script is working fine.

Any help would be greatly appreciated.

thanks,

Error while running subway.py

I’ve been trying to run the subway.py

But I keep getting the same error message

pi@raspberrypi:~/subway $ ./subway.py
Traceback (most recent call last):
File "./subway.py", line 171, in
m = Tk()
File "/usr/lib/python3.5/tkinter/init.py", line 1880, in init
self.tk = _tkinter.create(screenName, baseName, className, interactive, wantobjects, useTk, sync, use)
_tkinter.TclError: no display name and no $DISPLAY environment variable

I don’t know if I’m missing something

Thanks in advance

feedsToCheck Appears to Only Check One Feed Per Station

I'm trying to identify trains running on two lines, the A/C and B/D, arriving at Columbus Circle, station A24. The code, however, only returns the trains arriving on the B/D line, which are associated with feedsToCheck = BDFMfeednum. If I put ACEHfeednum ahead of BDFMfeednum, the code returns the trains arriving on the A/C line, but not the B/D line. I can't seem to get the code to return the trains running on both lines.

Any help would be greatly appreciated.

Getting some errors - not sure how to troubleshoot further. Happens when running as ./mta.py or as ./mta.py 127N 127S.

MTA sunsetting datamine.mta.info in favor of api.mta.info

Effective May 1, 2020, the MTA is shutting down datamine.mta.info, to which the script currently calls, in favor of using api.mta.info.

At a minimum, the feed number endpoints will need to change.

Display Size doesn't fit

I went with a different display then the one you listed and while everything works great now from a code perspective, if i have the pi connected to a monitor or a tv when i plug it into the small screen/case that i had intended run this on, the display is too large and you can only see the direction one way and the otherway is cut off. I went into raspi-config and set the resolution to 800 x 480 which is what the manufacturer lists. This seems to work fine for the regular desktop but not the subway time output. Is there an easy way to resize the output so that it will fit this screen correctly or would it make more sense for me to get a different screen and use this one for a different project down the road. Any assistance will definitely help and i apologize for asking you my previous question about tkinter since it would have been irrelevant if i had atually been using the raspian os instead of a basic ubuntu installation.

Stopped working this morning.

Everything was working and i was getting the correct times for my station, but starting this morning i noticed that the train time wasnt updating, and it stopped getting the train time. now when i try to run mta.py i get the following error. cant figure out why.
