Thank you! This helped! At the very least, I've got Ampy up and running and can toss some files onto the device. I've got the M5Stack Faces kit, and I'm using the factory firmware (rather than UIFlow). Now I'm working on getting the M5Stack libraries working... I found the githubs located here: http://community.m5stack.com/topic/724/micropython-firmware-with-m5stack-libraries
and managed to move over m5stack.py and input.py, but now m5stack.py is grumpy because it can't find the "display" module. Any pointers on where to go from here?
Alternatively, I suppose the UIFlow firmware probably has these libraries already... or it's using a different M5Stack.py maybe? Even in USB mode, I can't seem to access the REPL with the UIFlow firmware.
Thanks again, and sorry for leaning on the forums hard for this... it just feels like there ought to be a better way to get this to get this running a python file without the extra UIFlow interference. (I'm sure it's great for starting out, but I was hoping to use this more for prototyping, etc.)
