M5Dial and Canvas in Lcd module

Microbug

Hello,

I'm trying to use the Canvas in Micropython and can't get things working.

from M5 import Lcd
toto=Lcd.newCanvas(60,50)
print(toto.width(),toto.height())
toto.fillCircle(x=10,y=10,r=5,color=0xffffff) # centre
toto.push(0,0)

This does not display anything :/

I see that newCanvas can accept up to 4 arguments but can't find their signification.

Any help ?

Thansk !

Hello @Microbug

it looks like the circle is in the invisible upper left corner of the round display. Moving it helps. Try this:

  from M5 import Lcd
  Lcd.clear() # added
  toto=Lcd.newCanvas(60,50)
  print(toto.width(),toto.height())
  toto.fillCircle(x=50,y=40,r=5,color=0xffffff) # modified
  toto.push(0,0)

Thanks
Felix

Hello @Microbug

it looks like bits per pixel (bbp) and whether device has PSRAM or not. See here and here.
