Story
 

Just a day one small project I decided to post since there isn't much stuff about the m5paper. A slow drawing app you can load through UiFlow (https://flow.m5stack.com/) and you can erase what you drew by touching the very top of the screen.

 
 
Code
 
DrawingAlpha Python
 
This code is meant to be used with UiFlow. I know some people might prefer the visual scratch like code on UiFlow and others may go for the Arduino IDE if they are going to code it anyway, but I found this to be the fastest way to try out this new toy on day one.
Copy Code 
from m5stack import *
from m5ui import *
from uiflow import *
from m5stack import touch

setScreenColor(15)


TouchCordx = None
TouchCordy = None

title0 = M5Title(title="Title", x=3, fgcolor=15, bgcolor=0)


# Describe this function...
def SetTouchCordenate():
  global TouchCordx
  global TouchCordy
  TouchCordx, TouchCordy, s, status = touch.read()



setScreenColor(15)
lcd.show()
while True:
  if touch.status():
    SetTouchCordenate()
    if (TouchCordy < 80.0):
      lcd.clear()
      lcd.rect (0,0,2000,2000,15,15)
    else:
      lcd.circle(TouchCordx, TouchCordy, 20, 8, 8)
      lcd.partial_show(TouchCordx-20, TouchCordy-20, 40, 40)
  else:
    pass
