Today, OLEDVirtual 1.0.0 got released. It is a library to mock the
oled library for local development.
Now you can code interactions with an OLED screen without building a Nerves firmware and deploying it into the device for each change.
It also comes with a
MultiDisplay module to power both the real OLED screen and the virtual display at the same time, which is great if you want to keep a display preview in your web interface using e.g. Phoenix LiveView (guide included).
