I'm afraid you've identified all the possibilities for now . BTW, disabling wifi won't prevent the glitches but it does make them less likely to occur. MicroPython on the ESP32 is built on the ESPIDF which employs FreeRTOS; it interrupts the system periodically causing the timing glitches. There are...

I'm a happy Visual Studio Code user. The Python and Magic Python extensions provide good Python support and excellent syntax highlighting. On my radar is to use MicroPython Stubber and Micropy CLI both of which can help improve Intellisense. I've tried them out - and they look promising! - but haven...

Looks good Peter, thanks! But I tend to use FlatBuffers and MessagePack (and JSON/TOML for human-readable) depending on the use case. MessagePack when I want to allow dynamic messages to be constructed, FlatBuffers when implementing a protocol. At some point I'd like to see support for both of these...

Hi @shubham, Anyone has anymore solutions or suggestions? I think you have learnt most of this but just to recap... RMT is the right way to drive NeoPixels on the ESP32. Whether you use threads or asyncio the underlying OS (FreeRTOS) will periodically interrupt the system long enough to cause glitch...

If I were to guess it would be because the Matrix has 25x Neopixels, each of which consumes ~1mA even when off. An additional 25mA could make all the difference. Each board can behave differently with regards to power; for example your 'big' M5Stack Core may not exhibit problems if it has more capac...

Something else to check first - when the radio is active the ESP32 draws the most amount of current. It can sometimes spike to above 500mA and can reset if the power supply is inadequate. So perhaps quickly try a different USB power source and possibly even cable...

Seems to work for me: MicroPython v1.12-96-gc3095b37e on 2020-01-29; ESP32 module with ESP32 Type "help()" for more information. >>> import network >>> wlan = network.WLAN(network.STA_IF) I (57590) wifi: wifi driver task: 3ffbd98c, prio:23, stack:3584, core=0 I (61791) system_api: Base MAC address i...

I've got one each of the Matrix and the Lite but haven't yet tried connecting them to the network. I'm at work now but will try at lunch in a couple of hours!

'Seen GPL code before writing his own version' wasn't the issue here. A small amount of GPL code had been included in the repository and then was removed. It had not been re-implemented. And in reality, nobody can determine what you may have seen. In my work in the industry it has been sufficient t...

Thanks I like to follow these to see all the new exciting stuff that is coming :) Thanks for the feedback OotB; I'll keep 'em coming. :) The Wemos W600-PICO looked promising as an alternative to esp8266 but it isn't sold on Aliexpress anymore? Can't find it anywhere :/ The W600-PICO by Wemos is lis...
