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.
