Ok it's an old one but as I've found a solution...

1- Write your function code in test_code1.py for example, with a function dazi() inside.
2- Write your program code and on the top :
from apps import test_code1
3- when you want to use your dazi function, write then test_code1.dazi('.........../......')

It's working for me.

The latest update put the gray square always under the QRcode.OK
But why a gray square instead of the backcolor ?

Hello felix,

seems to work, thanks.
Will see how long m5paper could work without charge.

Hi,

Did you added "from easyIO import * " at the beginning ?

Hi, could you please post the Micropython code that I could tru the same on mine please ?

Hi, do you know the exact command in Micropython ?
Seems that machine.lightspleep(60000) works only if battery is charging and doesn't when the M5paper is away from USB....

Have you ever encountered this problem, and how did you solve it?

@belsonc said in ghost qr code on m5paper?:

setScreenColor(15)

I've the same problem.
I've you found a solution ?
