I'm trying to use some libraries that apparently have a call to "analogRead(A0);" which is also apparently not defined. Is there any way to work around this? I tried doing #define A0 32; before the library is included but that didn't help.

I have my display showing a constantly updating number, but this number doesn't ever get erased which makes it really hard to read after a short while.
I tried setting the whole display to black before doing each number but it creates a rolling effect...

Yes of course!

I know double pressing the power button turns it off while it's not plugged in but I can't seem to find any way to power it off while it's plugged in.

Also I can't seem to figure out how to power it off while its charging...

I agree, the bundled library for the screen graphics works but it would be nice to me able to change it out without having to edit the m5stack library itself.

I created a garage door opener that links to an esp8266 based relay connected to my garage: http://www.joeybabcock.me/blog/projects/gp-genius-project-prototype-1-garage-door-opener/
