MatrixPortal : solution to refresh the clock every second

[kabcasa]

I have a clock that needs to be updated every second on a first line and a second line that displays scrolling text.
currently the clock is only updated at the end of line 2 scrolling.
I am looking for a solution to refresh the clock every second independently of line 2

i have set the matrix :
<

# Matrix setup
print('Matrix Setup')
matrixportal = MatrixPortal(
    url = URL,
    json_path=FORECAST_TYPE,
    status_neopixel = board.NEOPIXEL,
    debug=True,
)

print('Text Setup')
matrixportal.add_text(
    text_font=terminalio.FONT,
    text_position=(10, 5),
    text_color=0xFF8080
)
matrixportal.add_text(
    text_font=terminalio.FONT,
    text_position=(0, 20),
    text_color=0x3ABCBC,
    scrolling=True
)

and for display :
<

matrixportal.set_text(curtime, 0)
matrixportal.set_text(next_station_in, 1)
matrixportal.scroll_text(SCROLL_DELAY)
time.sleep(0.03) 

I could get the clock update every second when using matrix.scroll() but get an issue
File "adafruit_matrixportal/matrixportal.py", line 231, in scroll
AttributeError: 'NoneType' object has no attribute 'x'

<
```
matrixportal.set_text(curtime, 0)
matrixportal.scroll()
matrixportal.set_text(next_station_in, 1)
matrixportal.scroll_text(SCROLL_DELAY)
time.sleep(0.03)

I'm pretty sure that's not possible with how it's currently coded. Now that asyncio is working in CircuitPython, this part could be rewritten.

@makermelissa
thanks for these informations. I have practically no asyncio experience, on your side do you have an example how to do it.

I haven't really used it, but here's a great guide on how to use it and what I would start with myself:

Did you ever find an implementation solution? @kabcasa
