OMG, serial console!

Maybe everyone else knows this, but I just discovered that you can connect to the M5stickC over the serial connection and get a python prompt!

@dclaar Welcome to the Micropython world.
This feature has been known and doumented several times, I think @lukasmaximus made a video for it.

BTW if you use the new beta firmware (1.5.0) use Mu as the IDE as it make coding so much easer.
BTW2: you can also access it in vstudio.

Hi

I have found Thonny a nice editor as well, it lets you interact with the shell and transfer files.

@ajb2k3 Thanks! I figured that somebody knew about it, but I had searched for various terms like serial, console, debug, etc, and didn't find it, so I thought I'd post this to perhaps help others find it. :)

Thanks for the IDE recommendations.

I like vstudio because I can load the vim extension and pretend that I'm using a terminal. :)
(Shoveling python is my day job, so I don't tend to use an ide unless I have to).

The serial console access is known as REPL.
If you didn't know about REPL then it is no wonder that you are surprised.
