Re: Adafruit uRTC library for real time clock modules

very old thread. Sorry I am running MicroPython v1.9.3-8 on a WEMOS D1 Mini ESP8266. While the ESP8266 is connected, I am able to set the ESP RTC by using the npttime library. This is ok until I turn off the power, or drop into deepsleep. So I have a DS1307 shield which I have tried to use with the ...

Monitoring Battery Supply to an ESP

I would like an idea of remaining juice left in a battery supplying my WEMOS D1 mini via a battery shield . A previous thread in this forum indicated that the ability to monitor the supply voltage, while available in the ESP, is not implemented in Micropython. Is this still the case? I read a lot of...

Re: ESP32 and LoRa

You can run the code for Pycom's WiPy on any ESP32 board with a Rev 0 chip. It will also run on Rev 1 chip boards with external psRAM like the Wemos Lolin32 Pro. The Pycom software assumes, that all Rev 1 boards have that additional RAM. I hacked a version which also runs on Boards with a ESP32 Rev...

Re: Talks and videos about MicroPython

Also at the same conference, Andy Gelme introduces a open hardware 'lollibot' programmed with micropython . More on the hardware for those who are interested. Does anyone have any idea how I can get hold of one of the kits (or just the PCB) for this lollibot? I have contacted the organisers but got ...

Re: Pyboard+Micropython questions

Hi Jayant, Its great you are encouraging your son in microcontrollers! Even better that you are considering Micropython. 1 &2) i agree with @deshipu, as a beginner you son may get more from Adafruit's range; Huzzah feather series for example. They have a great series of shields with good online tuto...

Re: On analog pin change?

I just rembered this post from a while back and thought I must finish it up if other forum users search up similar questions. Many thanks @hase, @pythoncoder and @roberthh for the help and encouragement to dabble into Schmitt triggers. I spent some time reading about them and then realised that thes...

microSD card - clarification

Please can someone clarify the correct approach/best approach to interact with a microSD card with a ESP8266. My use case is to save sensor data as files to a microSD card. Periodically, connecting to wifi and sending the data files back to a remote MQTT broker. I am using a Wemos D1Mini and have a ...
