DS18B20 temperature sensor

[duzymaju]

I'd like to read temperature from DS18B20 OneWire temperature sensor. I haven't found any Kaluma library to support it. If there is really nothing which can be used to support it (I'm new here), is there maybe OneWire library then or it also needs to be prepared from scratch?

There are proper MicroPython libraries:

• https://github.com/micropython/micropython/blob/master/extmod/modonewire.c
• https://github.com/micropython/micropython/blob/master/drivers/onewire/onewire.py
• https://github.com/micropython/micropython/blob/master/drivers/onewire/ds18x20.py

@duzymaju Currently onewire protocol is not supported, so we open an issue (#484) for onewire protocol.

Alternatively you can use pulseRead() and pulseWrite() to read and write signal in microseconds-level. DHT11 is an example for reading digital signals from an single wire.

Thanks for the answer. I will try to use pulseRead() then or wait for #484. :)

Hello @duzymaju.
Did you manage to figure out the temperature reading?

Hi @sergeychernov. Unfortunately I haven't done it (I tried without success) with very limited time for start supporting onewire protocol and I decided to use MicroPython instead. But I'm still interested in using of Kaluma in my future projects hoping that someone is going to implement #484 one day. :)
