Hi! I just shared a simple and small project on Github. I hope it can be useful for someone. Monitor Ring Light - A custom ring light around a monitor, providing uniform lighting and custom color toning for video recordings and video meetings. Made with RGB LED Pixels (WS2801), ESP32, MicroPython an...

Thanks for the code, razanur! I hope you don't mind me using and sharing your code (with credits) on a small project. If anyone is interested, you can see the PC and ESP32 code on Github: https://raw.githubusercontent.com/AltoRetrato/monitor-ring-light/main/images/monitor_ring_light.jpg Monitor Ring...

Hi there! I did something similar a while ago, but writing the data in the filesystem instead of sending it to a server. It worked fine, but sometimes when power was lost the littleFS filesystem got corrupted... Is your code writing anything to the filesystem? If it is, is it closing the file(s) bef...

You can always delegate instead of inheriting:

True! It is a bigger workaround, though, but one to keep in mind. Thanks!

Looks like you've hit the target! Thanks, Christian!

Oddly enough, this code works on MicroPython:

Code: Select all

class Cfg(dict):
    pass

cfg = Cfg()
cfg.update({"rate": 30})
print(cfg)

The result is, as expected:

Code: Select all

{'rate': 30}

Now I'm using something like this as a workaround, but I wonder if this issue is a bug in MicroPython...

Hi there! The code below runs fine on CPython (versions 2.7.16, 3.4.10, 3.7.0, ...), but produces a "TypeError" on MicroPython (ESP32 firmware esp32-idf3-20200618-unstable-v1.12-554-gce02d5e34): class Cfg(dict): def __init__(self, default={}): self.update(default) cfg = Cfg(default={"rate": 30}) pri...

I lost my LittleFS partition. It seems it isn't resilient to power failure after all, at least on the ESP32 with firmware esp32-idf3-20200509-unstable-v1.12-447-gab4e19770. Everything was working fine for a few days, including powering the system up and down several times. Today I disconnected the p...

Thank you all for your information and tips!

Hi! I'm about to write a simple humidity / temperature logger using an ESP32. Sensor data will be collected at least once per minute, and the device should run 24/7, for several days, powered by a phone charger. There is no Wi-Fi nearby most of the time, so I have to store data at least momentarily ...
