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...

Re: microSD card - clarification
sadly os.unmount(True) returns the old OSError: [Errno 22] EINVAL ...invalid argument! I have also tried following the Adafruit tutorial and that also fails on >>> vfs=os.VfsFat(sd, "") Traceback (most recent call last): File "<stdin>", line 1, in <module> TypeError: function takes 1 positional argu...

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 ...

Re: Newb Teacher Needs Help
AMPY is good. Rshell https://github.com/dhylands/rshell is developed by one of our own, and in my opinion is better! ;) Just a short word of encouragement, I did not know one word of any computer language 12 months ago. I started learning Python from scratch and then came across Micropython. I am re...

Re: ESP32 and LoRa
It looks like someone implemented or imported a driver for the sx1276 LoRa module in a fork of PyCom's Micropython? All written in C of course. https://github.com/aizukanne/ESP32-micropython-lora/tree/master/esp32/lora Also I am seeing what looks like some LoRaWAN-related code in the PyCom reposito...

Re: ESP32 and LoRa
I wonder if I can drag this thread back to the original question.
Has anyone actually connected using LoRaWAN (to The Things Network most probably) using Micropython-programmed:
-RAK811?
-Heltec board?
-hand-made RFM95W connected to a ESP32?
What libraries did you use? any problems along the way?

Re: RFM95W lorawan stack ?
thanks for the links @on4aa, I will try and dive into aizukanne's fork of Pycom. But as a beginner, I really don't have the expertise to take, understand and use a module in this early stage of development. It seems I may be stuck using Arduino for a while, or perhaps stick with my trusty LoPy inste...

Re: SSD1306 I2C
sorry @pythoncoder, I forgot I wrote some notes at the top of the SSD1306.py module to remind me why I used an older version! So that is what threw the line numbering (poor coding mistake!) :oops: I really don't know how you put up with such poor mistakes! Thanks. Now with the OLED object correctly ...
