MicroPython Forum

I'd say this is a bug, not a difference. Probably an oversight during some changes last year to the comparator.

Thanks to @pythoncoder for pointing me to this thread, I somehow just always skipped it without reading, which was wrong, because I think I can contribute to your discussion: Some time ago I tried using class variables as a common information storage accessible to multiple class instances (in read/w...

hmm can you use ubuntu wsl?
maybe cpython on windows doesnt have select.poll

both links are for pyboard, esp8266 and esp32 and partly even the unix port.
You dont need to do any changes.

I once bought a MQ-5 too to detect gas in my appartment. Never got it implemented though.. This link was interesting for me: https://osoyoo.com/2018/11/15/arduino-lesson-mq-5-gas-sensor/ From that page: The sensor value only reflects the approximated trend of gas concentration in a permissible error...

Can't say anything about the accelerometer but for sending messages between micropython and a python server I can recommend this project: https://github.com/peterhinch/micropython-iot It provides a reliable client-server connection, so you don't have to worry about that. However, it uses uasyncio so...

The relevant source for time.time() is here: https://github.com/micropython/micropython/blob/073b9a5eb888b26be7ce4c65e9649b6c3857ba39/ports/esp8266/machine_rtc.c#L99 (this function is called in time.time() in modutime.c that @peterhinch linked to) As I understand it, it uses the rtc directly for thi...

the accuracy of time.time() should be the same with or without uasyncio. uasyncio doesnt change the time and it uses ticks_ms() internally.
The rtc accuracy of the esp8266 generally is horrible but not 3 secs per minute usually. Maybe try a different board and see if it behaves better.

The lobo repo has many esp32 specific features that the main micropython repo only got recently or didn't yet implement at all (because it is more difficult if you have to implement things that have to be consistent over multiple ports and not only the esp32). Therefore the lobo port might still be ...

I'm glad it works now! by the way: the last 2 lines are not needed in your code: import machine import uasyncio as asyncio from pms.pms5003 import PMS5003 import pms.pms5003 import time import epaper2in9 from pyb import SPI import pyb # SPI3 on Black STM32F407VET6 spi = SPI(2, SPI.MASTER, baudrate=2...
