Hi @mcwTexas. I don’t know much about these things. Now I put it running and my task manager doesn’t show increasing number of scrolling-text-example processes. Only one Sh too.
Maybe asking from others, which knows about coding.

My line is
os.system(sudo ./scrolling-text-example -f ../fonts/9x15.bdf -y0 -s9 -l2 -C ”+ randomColor +” —led-cols=32 —led-rows=16 —led-brightness=75 —led-chain=3 ”+title)

feedparser.pyc is also on examples-api-use-folder as is rssparse.py.
