Re: FOSDEM 2017?
I had to withdraw a suggestion to show Saltstacks "proxy minion" feature to sync files with a micropython ESP8266 bringing this board effectively under config management. Maybe another year -- but too busy with real life in 2017.

Re: [SOLVED/WORKEDAROUND] Having problems with HX711 load cell sensor
Ah, disabling interrupts is what I'll do, too -- I am still new to all this. That data = "" was more for debugging, because for a few moments I wasn't sure if repeated calls to .value() might mess up with the HX711 shifting out bits :) All these print statements must go away anyways. Thanks for the ...

Re: Having problems with HX711 load cell sensor
Hi Robert, thank YOU ! I had to get up in the middle of the night and try the frequency change and indeed I now get: - with a 0.5kg weight - without a weight >>> f = HX711() <waiting finished> dataPin: 0, sckPin: 0 bitbanged: 15240832 us: , 228, 202, 216, 215, 201, 198, 212, 216, 194, 216, 212, 194,...

Re: Having problems with HX711 load cell sensor
Ahhhh, the code is too slow!!! *heureka* Now this was just plain stupid: for i in range(24): self.pdsckPin.high() time.sleep_us(2) print("<{}> dataPin: {}, sckPin: {}".format(i, self.dataPin.value(), self.pdsckPin.value())) self.pdsckPin.low() #print(i, self.dataPin.value(), self.pdsckPin.value()) t...

[SOLVED/WORKEDAROUND] Having problems with HX711 load cell sensor
Hello everybody, I am trying to read from this popular HX711 breakout board with an Adafruit Huzzah ESP8266 and a stock esp8266-20161110-v1.8.6.bin This is the component for a digital scale, sparkfun has some pictures. This chip has a non-standard protocol, the datasheet describes: Serial Interface ...

October 22 firmware self-compilation
Hi there, this is how I got it to work with the vagrant file from https://learn.adafruit.com/building-and-running-micropython-on-the-esp8266/flash-firmware . I followed it today and yesterday with _some_ success. There is a switch in pfalcons esp-open-sdk to SDK v2.0 https://github.com/pfalcon/esp-o...

Re: Capturing stdout from exec()
Funny, I came here the exact same way as the OP: I want to remote-execute code on an ESP8266 by means of pyboard.py wrappers (e.g. mpfshell). My first, randomly chosen, sample was to get the output of esp.check_fw() which not just does return True/False but also prints out 'stuff'. So over the seria...

Re: mpfshell now supports connections via websockets
Hi, I finished basic support for connecting with the "shell" to the ESP8266 via websockets (WebREPL needs to be active). Thus, all the shell operations (like put, get, full REPL, ...) are usable via a WiFi connection. Hi Stefan, What are your thoughts on this usecase: I am looking for a "glue" betw...
