Looks like rtc is included in one of the other files
from m5stack import * from m5ui import * from uiflow import * setScreenColor(0x111111) rtc.setTime(0, 0, 0, 0, 0, 0)
I tried to fill this in but easily distr........
When devices start up, go to setting and set connection mode to USB. Default is set to Wifi/usb.
UIFlow is built on a version of MP 1.12 as so micropython can be accessed directly over the USB.
However because it is based on MP1.12 so of the modules not required by UIFlow may have been removed.
Any IDE that can access MP over USB can be used to program M5Stack cores and sticks.
