@lukasmaximus 在 MicroPython lcd.qrcode is not work 中说：

uiflow

Thank you for your reply!
By your explanation, I understand that there is a difference between the two services.

I was thinking of using M5 Cloud Offline to use M5 Stack offline.

I usually use Python, so I wanted to use microPython.

However, given the richness of the library, I felt it should be implemented with cpp.

In the future, if microPython 's functions are enhanced, I would like to try again.

Hello

Please let me ask a question about microPython.

Regular M5 Cloud no
MicroPython does not have lcd.qrcode.
https://github.com/m5stack/M5Cloud#lcd
However, M5 Flow UI has lcd.qrcode.

Is there a way to use lcd.qrcode with M5 Cloud?
Is there specification information on lcd.qrcode of M5 Flow UI?
