Re: The state of the community

Dear Deshipu I was pretty sure somebody would have rised this topic, and I was ready to bet it would be you ;) Indeed, it is time for a balance of MicroPython status especially with the forthcoming generations of IoT micro devices. I am one of the guys coming from NodeMCU/LUA and Arduino development...

Re: 3.3 V range on the A0 analog input of Wemos D1 mini

Robert thank you very much (also to host me in your thread but maybe I can move the whole thing if it gets too fat here ;) However I am a bit puzzled. I use a piezo buzzer (this one from https://wholesaler.alibaba.com/product-detail/SFM-27-W-12v-buzzer-alarm_2004283581.html I use exactly the SFM-27-...

Re: 3.3 V range on the A0 analog input of Wemos D1 mini

Thank you Robert, very interesting. I don't know if I may use your thread to post some more information about WeMos D1 mini and pose some questions. If not I can change topic and move to a more specific one. I measured the PIN Voltages just after a POWER UP and I found some interesting results. I me...

Re: RFC: Not enabling WebREPL by default on boot

Dear @pfalcon (Paul if I can), thanks you for your replies. By the way I think 1.8.6 implementation is a big step ahead with webrepl usability. Regarding clear passwords I have one more use case... just make a laugh, it's a funny story :D Recently I gave away a couple of WeMos devices with my microp...

Re: Could not erase flash

It looks like a bad flash / corrupted file system. Check again all the toolchain. The xtensa compiler, the esp_sdk, the esptool.py. It can be also a corrupted flash but most likely is the software toolchain. Some people had some result shifting from Windows to Ubuntu or Mac. This is kinda magic I ca...

Re: ESPLORER unable to run a proper main.py file ...

I think Esplorer is faaaar from updated to support to micropython. dofile() is a LUA NodeMCU function which is not suited for micropython. In other words forget it... ;) If you browse the forum, you'll discover much more effective ways to develop with micropython and target devices like ESP8266. You...

Re: Avoid flash wearing by altering behavior originally introduced by Espressif (the inventor of the ESP8266)

Read the whole thread (twice). Read the two pull requests mentioned (https://github.com/micropython/micropython/pull/2510 and https://github.com/micropython/micropython/pull/2564). I am a little confused so forgive me if I missed something. 1. I have almost the same problem of @kfricke with my appli...

Re: Can't flash 1.8.5 (or 1.8.4) on NodeMCU

Looks to me a bad flash or a bad image: in that case the unit continue rebooting flashing the LED. It happened to me something similar NodeMCU was working fine and Micropython was flashing. Connecting with picocom presented garbled characters on screen continuously. As @kfricke noted, my problem was...

Re: Development Cycle for the Wemos D1 Mini from Windows

Window with maybe cygwin or even with the ubuntu shell will do the same I guess. Not to mention with Mac. Many platforms, same way to develop.. that's my motto. Enjoy!
