Re: Micropython as Arduino killer

... As for libraries, I think we all know that this is an area Micropython could improve. They tend to be scattered across github and the best option to find what you need is usually to search, then if needed post, in this forum! Perhaps this interest is a trigger to pull together the libraries in ...

Adafruit tinyLoRa LoRaWAN library

Adafruit has just released a new TinyLoRa library that allows access to TheThingsNetwork using LoRaWAN. The library, of course, uses their Circuitpython fork, however this is relatively easy to map to Micropython. The RFM95 radio transceiver is used. For those with an interest in TheThingsNetwork , ...

Re: Problems connecting to ESP8266 with picocom

like so many things related to Micropython, you can find amazing things by digging in this forum! post https://forum.micropython.org/viewtopic.php?t=3860 covers a few variants of ESP boards, including yours. I recall seeing a similar thread covering lots of ESP32 variants but I cannot find it now!

Re: Micropython as Arduino killer

Matt, I think a key area that could do with some focus is use of the Micropython REPL. In Andreas' inital video he skips over this, but I think this is the the massive initial advantage for those arriving to Micropython from Arduino. The ability to directly interface with the bare metal and through ...

Micropython as Arduino killer

I know i am not supposed to just post links on the forum. However Andreas Spiess is a legend in the Maker world. His latest video, despite being a bit frustrating for Micropython users, is still excellent publicity.
I hope this video brings more people into the community.

Re: New Lolin D32 Pro with 4MB PSRAM

Has anyone had problems with the LiPo connection on D32Pro? I have been running along fine with USB serial power. I get a decent reading at the battery terminals on the board, but nothing further in. Even VBAT has nothing ?!? I have a Lolin32 Pro V1.0.0 (with apparently the same battery circuit) whi...

Re: best way to store datestamps in upython

thanks @jickster and @pythoncoder for responding. The use case at present is simply recording a timestamp on an uSD card. At some point this uSD will be retrieved and data extraction and manipulation will outside the system. So I suppose I meant that 'optimising' means simple, efficient in time and ...

best way to store datestamps in upython

This is a general question from a novice. What is the optimal approach (in Micropython) to store a series of timestamps? My use case is a bike counter. A radar sensor triggers a Pin on the rising edge of a ESP32 dev board, waking it from DeepSleep. I am recording the time of the external Pin interru...

Re: TinyRTC I2C Module DS1307 + AT24C32N

continuity appeared fine. With a more detailed search around I found others complaining of similar problems . In common with the author of the link, the D1 diode was defective on both my shields. I removed the diode and resistor R5 completely and the RTC module now works. As the IC appears to be ok ...
