4 years ago Hey, thank you for submitting this update to the documentation! I'm so sorry this PR has been open for ~2 months. I haven't had as much bandwidth for side projects since COVID-19 began.
I'm going to add this revision into the release-1.2.0 branch 🎉
I edited the README to include a fix for an edge case a user might experience on a Raspberry 4 and following the Medium article tutorial.
I followed the steps in Medium article, I ran into issues on Raspberry Pi 4 running Rasberian (Feb 2020). After initializing the python virtual env and running "rpi-deep-pantilt test pantilt" I received the error noted below. This Github comment helped to resolve the issue.
