I saw this the other day and thought to myself, “there is another piece of cool crap I don’t need, buut as so the story goes…
Has a cool1.4” screen with a whooping 16mb of flash, convenient usb a form factor, meaning that 
that this WILL be very convenient as a room multisensor that can be plugged in to the wall, profit 
.
After getting it, realized I don’t know anything 
about this screen (aka spi bus pins and so) and the wiki and almost inexistent github official WaveShare presence, offered very little information (just an observation as this being my first experience with this manufacturer).
Searched around, but did not find any post, mention or even similar, so I guess I 'd throw stuff to the wall to see if it would stick, and it did.
This is how I made it initialize the display(and other stuff I’d learn thanks to other posting here), hope is of use for someone:
