@favnec5 Here is another Micropython port for the Core2. Already thried that with my core2: https://github.com/thuehlinger/micropython-core2

Another note: you do not need to use another firmware, you can use Micropython directly by just not using uiflow. See my repo https://github.com/hjgode/m5home within the lv dir: lv_test.py
Be warned, the LV Binding is not very well documented and often only links to the C API.

I have done a nice info panel using MQTT. As I am in Germany, I also get german umlauts (äöüßÄÖÜ) in MQTT payloads. But these will display without the umlauts in M5Label, so instead of 'fällt' I get 'fllt' or for 'bewölkt' I get 'bewlkt'.
If I use rshell or similar to connect to the Core2, I can print umlauts in the Console (ie print('bewölkt')) and I verified the MQTT payload content prints correctly in the console. Just M5Label does not show the umlauts. The MQTT payload is encoded as utf-8.

What is wrong?

You can have multiple screens, for example in an array, and then switch the screens with screen.load_screen(screens[i])

I use it like this

screen = M5Screen()
screen.clean_screen()
screen.set_screen_bg_color(0xadefeb)
screen.set_screen_brightness(60)
#an array to store screens
screens=[]

now everything (M5Label etc) will be drawn on the current screen.
I end the screen with
screen0 = screen.get_act_screen()
screens.append(screen0)

then start a new screen with

get a new screen

screen1 = screen.get_new_screen()
screen.load_screen(screen1)
then end this screen and so on
screen1 = screen.get_act_screen()
screens.append(screen1)

To switch the screen I use
def getPrevScreen():
global current_screen, screens
lock_obj.acquire()
print('getPrevScreen called')
current_screen-=1
if current_screen < 0 :
current_screen=0
else:
screen.load_screen(screens[current_screen])
lock_obj.release()
pass
def getNextScreen():
global current_screen, screens
lock_obj.acquire()
print('getNextScreen called')
current_screen+=1
if current_screen > len(screens)-1 :
current_screen=len(screens)-1
else:
screen.load_screen(screens[current_screen])
lock_obj.release()
pass
these are called by
def buttonA_wasPressed():

global params

do_beep()
reset_idle_counter()
print('ButtonA pressed')

screen.clean_screen()

screen.load_screen(screen0)

screen.load_screen(screens[0])

getPrevScreen()

_thread.start_new_thread(getPrevScreen, ())
pass
btnA.wasPressed(buttonA_wasPressed)
and
def buttonC_wasPressed():
do_beep()
reset_idle_counter()
print('ButtonC pressed')

screen.clean_screen()

screen.load_screen(screen2)

getNextScreen()

_thread.start_new_thread(getNextScreen, ())

screen.clean_screen()

screen.load_screen(screen1)

screen.load_screen(screens[2])

pass
btnC.wasPressed(buttonC_wasPressed)

The formatting here is terrible, as it reads # for markdown...

I will put my code on github (hjgode) later on

BTW: the UIFlow doc is a mess. They use // in fron of line for a python comment line (needs to be a # in front). And I am missing examples, examples....
Still looking for a complete developer doc for the UIFlow micropython stuff. Some functions are named differently and some just do not work, if you try the micropython basic ones (like for example umqtt.simple, which just crashes as someone forget to implement socket.set_timeout)
