@davef, thanks for sharing that code. I'll add Peter Hinch's fix to settime. In my application, NTP is only correcting the DS3231 RTC, which is pretty accurate for long periods, but battery life is limiting. So having time resets work only some of the time is less problematic than long delays during...

Has anyone made progress on this issue? I've encountered similar flakiness with ntptime.py (borrowed as above from the ESP8266 port) using MicroPython v1.18 on a PYBD-SF2W. However, a hard reboot to reset the wifi seems at this point unnecessary. I've set s.settimeout(10) #s.settimeout(1) in ntptime...

A driver for SI1132 sensors, minimally modified from https://github.com/ControlEverythingCommunity/SI1132 to work in micropython on an ESP8266. It uses SMBus emulation from https://github.com/gkluoe/micropython-smbus . Example: from machine import Pin from usmbus import SMBus from si1132 import SI11...

Has anyone made progress on this issue? I'm working on an Adafruit STM32F405 Feather Express, with the firmware Adafruit provides at https://cdn-learn.adafruit.com/assets/assets/000/083/671/original/micropython_1.9.4_Feather_STM32F405.zip?1573009976 I'm able to access the filesystem (and, simultaneo...

I've been using mpfshell on my ubuntu machines for serial communications with ESP8266 HUZZAH Breakout boards, which has been working very well (many thanks, @wendlers!). I'm now trying to help some students who use OS X machines. mpfshell installs via setup.py and appears to launch without errors th...

Thanks for these suggestions! I have an analog IR distance sensor -- I can work out the the power issues temporarily while I wait for one of the I2C sensors. I'll give it a try. I'm still interested in the acoustic sensor, if it is workable. Using sound as a sensing mechanism has some intrinsic valu...

Hello all, I've been using teensies and the like for teaching a mixture of technology and environmental science at the University level and also in middle and high school classes. My goals are to entrain the many students for whom hands on learning works better than listening to lectures. This inclu...

Hi! I'm very interested in the potential of using inexpensive acoustic sensors for tide and wave measurements. Thanks for posting your work in progress. Are there any updates on your results and advice?

Some more specifics for an array of six DS18B20 sensors. With DS18X20 from frozen bytecode: from machine import Pin from onewire import OneWire from time import sleep_ms from ds18x20 import DS18X20 p12 = Pin(12, Pin.OUT) p12.high() p14 = Pin(14, Pin.OUT) p14.low() ow = OneWire(Pin(13)) print(ow.scan...

As far as I can tell there is an issue reading DS18B20 sensors with recent firmware, where the normal usage fails during the DS18X20.scan() call. That seems to be because the filter for DS18X20 types onewire devices rejects ROMs that it should accept (or else the ROMs are being read incorrectly). Re...
