Display arrival times for Pittsburgh Port Authority buses on an RGB matrix

pgh-next-rgbus's Issues

Package rgbmatrix no longer exists

Looks like the rgbmatrix package is no longer available on PyPI. As a workaround, we can clone the parent repo at https://github.com/hzeller/rpi-rgb-led-matrix into a sibling directory to pgh-next-rgbus, e.g.:

pi@pi3-nextbus:~/src/pgh-next-rgbus$ ls -al ..
total 2492
drwxr-xr-x  8 pi pi    4096 Jan 18  2020 .
drwxr-xr-x 23 pi pi    4096 Nov  5 11:57 ..
drwxr-xr-x  9 pi pi    4096 Nov  5 12:01 pgh-next-rgbus
drwxr-xr-x 10 pi pi    4096 Oct  7  2019 rpi-rgb-led-matrix

and then update requirements.txt to point to the relative path of the python bindings in that repo:

../rpi-rgb-led-matrix/bindings/python/

Add timestamps to debug logs

Handle API downtime gracefully
