Newbie failing on the first clock + battery with PaperS3

literakl

I bought PaperS3 to build a dashboard displaying current time, weather forecast and bus departures. So far, I am unable to build a skeleton even after three weeks. My intention is to display the current time and a battery level and take a sleep for one minute. When running on a battery, I use deep sleep, because I target charging once per month. If connected to USB, I use a standard sleep to keep the USB connection (deep sleep kills it). Can you review my latest code please?

import M5
from M5 import *
import time, machine

SLEEP_MS = 60_000
WIDTH = 540

def get_battery():
    try:
        return Power.getBatteryLevel()
    except:
        return None

def is_charging():
    try:
        return Power.isCharging()
    except:
        return False

def draw_screen():
    Widgets.setRotation(2)
    Widgets.fillScreen(0xFFFFFF)

    t = time.localtime()
    day = t[2]
    month = t[1]
    year = t[0]
    h = t[3]
    m = t[4]

    batt = get_battery()
    batt_str = f"{batt}%" if batt is not None else "--%"

    date_str = f"{day}.{month}.{year}"
    time_str = f"{h:02d}:{m:02d}"
    battery_str = f"Battery: {batt_str}"

    FONT = Widgets.FONTS.DejaVu56

    y_start = 250
    spacing = 120

    Widgets.Label(date_str, WIDTH//2 - 100, y_start, 1.0,
                  0x000000, 0xFFFFFF, FONT)

    Widgets.Label(time_str, WIDTH//2 - 75, y_start + spacing, 1.0,
                  0x000000, 0xFFFFFF, FONT)

    Widgets.Label(battery_str, WIDTH//2 - 175, y_start + spacing * 2, 1.0,
                  0x000000, 0xFFFFFF, FONT)

    M5.update()

def main():
    M5.begin()

    if is_charging():
        while True:
            draw_screen()
            time.sleep(2)
            try:
                machine.lightsleep(SLEEP_MS)
            except:
                time.sleep_ms(SLEEP_MS)
    else:
        draw_screen()
        time.sleep(2)
        try:
            machine.deepsleep(SLEEP_MS)
        except:
            time.sleep_ms(SLEEP_MS)

if __name__ == "__main__":
    main()

So far I used AI tools to build the code. Thank you

@literakl so are you able to display current time and battery level at all...forget about sleep option for now
