<![CDATA[M5Dial and Canvas in Lcd module]]>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 !

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

Thanks

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
