Display Not Functioning

Thanks for creating such an awesome project like this! I heard about it from DCist.
I followed all of the directions, including getting the same supplies (two Adafruit 64x32 boards, matrix HAT, etc.) and plugged everything in, but I can't seem to get the displays to run.
Edit: I confirmed using some demos from rpi-rgb-led-matrix that everything is wired properly. I've re-imaged and installed again thinking I missed something the first time around, but the program still won't run.
If you have any ideas about what I'm missing, I would appreciate it!

Is there a log.txt that's been created in the rpi-metro-display folder? Can you post the output? What happens if you try running sudo ./run.sh from the rpi-metro-display directory directly?
dbsirota commented
Here is the output log.txt file. Running sudo ./run.sh from that directory seems to do nothing - the display doesn't run.

What's the output of running python --version. I suspect that you're trying to run Python 3 on Python 2 code or vice versa. Are you on the master (default) branch or have you switched to another?
If the output of python --version shows you're using Python 3 then you'll need to switch to the Python 3 branch of this code. I've been meaning to make the Python 3 version the default but haven't gotten around to it.
git checkout update/python3
Then you'll want to redo step 2 from the Install rpi-metro-display section of the guide when looking at the Readme version from that branch (linked above).
Then skip back down to step 7 and do the pip install:
sudo python3 -m pip install --break-system-packages -r requirements.txt
Let me know if that helps :)
dbsirota commented
Definitely got closer! I was running some weird hybrid between the original branch and the Python 3 branch because I didn't know the latter existed and was trying to make it work on my own. But this time, during the pip install I encountered a very long error involving building Pillow.

Have you installed everything from step 2 again? A lot changed from the python 2 branch to python 3
sudo apt install build-essential python3 python3-all-dev python3-setuptools python3-wheel python3-pip git zlib1g-dev libopenjp2-7I suspect that you're missing the jpeg dependency for Pillow which for Python3 you'll need to get from libopenjp2-7 at the end of the above line, but that part doesn't come from this codebase so I'm not sure.
Worst case you could try a re-imaging the SD card and starting fresh and just making sure you use the README from the Python 3 branch:
https://github.com/kenschneider18/rpi-metro-display/blob/update/python3/README.md

Got it working!!
I did a full re-image and realized where I was running into an issue. In the updated branch, step 6's command was having me download the master branch and not the updated one. When I would go to install the dependencies, that long error with Pillow would pop up and cause it to crash because it was pulling the master's requirements.txt file instead of the update/python3's file.
I changed the command to git clone -b update/python3 https://github.com/kenschneider18/rpi-metro-display.git and was able to continue with the installation with no errors and got it up and running shortly thereafter.
One last question - what do you recommend for joining the displays together and creating that nice case I can see in the demo photos? Would love to do something similar to that.
Thank you for all your help! Now time to make this a permanent setup 🙂
dbsirota commented
Okay, so it turns out there's still an issue, albeit much, much smaller than before.
Whenever the display boots up, only the nearest train shows up normally on the screen. The bottom two appear with in red and are missing the car list. This is consistent as each train departs and clears off the board.
kenschneider18 commented
Was it at one point showing the correct colors? My money is on this being some sort of hardware issue, especially since the bottom of the "y" in the second line is red., I would check all your connections between the hat, the Pi, and the two displays.
dbsirota commented
That was it - the data cable from the hat to the first display was a bit loose. I unplugged it and plugged it back in, jiggled it a little, and good to go!
kenschneider18 commented
Glad to hear it, congrats on getting it up and running!
Going to close this out since your issue is resolved :)
