where to find K10 and M10 Micropython documentation?

hi,

I'm looking for K10 and M10 Micropython documentation for the unihiker_k10 , k10_base (as mentioned here: https://www.unihiker.com/wiki/K10/Examples/examples_mpy/) and the pinpong and unihiker, specially about GUI (as mentioned here https://learn.dfrobot.com/makelog-313297.html)

is there any py docs reference for available classes/methods and functions, arguments and returns?

I've found some examples of display calls (specially using Mindplus) that suggest some kind of double-buffering for screens (like pre-drawing everything and then calling “show”), but I also found examples that just call the drawing primitives, so… I'm looking for some reference to study.

what if, for example, I want some kind of simple animation, like plotting a text continuously with the sound level. should I erase what area of screen with draw.rect the draw.text again? or should I buffer a second screen and swap?

I also read something about Tk components, like buttons and inputs. is there any documentation about this?

I'm about to follow the tutorials here:
https://learn.dfrobot.com/course-691.html
https://learn.dfrobot.com/course-699.html

but I would also like studying the docs if available.

thanks in advance :)
