Modules not presents

[hargathor]

Hi and first thanks for this for of micropython that is really impressive ! I've made an update this morning from the version 2.0.8 to the versoin 3.1.0 and some of the modules I used were not present. ds18x20 or onwire for exemple. Here is the output of help('modules') for official micropython 1.9.3

Those modules are frozen modules. Boris can confirm this information.

I still have my old folder and this would be the file to add to your modules folder (components\micropython\esp32\modules onewire.py.zip

We could have them at another folder so people can drag and drop what is needed. A more detailed documentation could be done also on how to build your own firmware. I am not fully capable of changing all I want for now, but soon.

Again, Thanks Boris for all your work !

Regards, Benoit Despatis, P.Eng.

I checked again, and you can see them at components\micropython\drivers\onewire

Also at components\micropython\esp32\modules_examples\ds18x20 ds18x20.py.zip

Hi @bdespatis

Thanks for the reply and for the files !

I tried to add other module files to this folder but the version wasn't good since I was missing other dependencies that I couldn't find. But I have nothing under the path you mentionning

$ ls -1 components/micropython/esp32/modules_examples/
bme280.py
lora
main.py
mqtt_example.py
ssd1306_i2c_example.py
ssd1306_spi_example.py
tft
thread_example.py
webserver

$ ls -1 components/micropython/drivers/
cc3000
cc3100
display
memory
nrf24l01
README.md
sdcard
wiznet5k

Maybe I can try to patch the documentation by explaining the how-to add other modules to the firmware ? I can try if it's ok.

What do you want to say by frozen modules ?

Regards Romain

[bdespatis]

Try import machine. I will check tomorrow if I can compile it. I suspect that one wire is builtin machine now.

[hargathor]

Thanks for the link I wasn't aware of what "frozen modules" were. It's really interesting.

I will build the firmware and flash it. I don't have a ds18b20 or another onewire sensor to test it right now but I will try to import module by repl just to check if everything is ok. I'm a little concerned about an import inside the onewire: _onewire. I can't see it anywhere. Actually this was my previous issue when I was testing with others module files (that's what I was talking about previously)

[hargathor]

As expected the _onewire module is missing. No issue for the ds18x20 though. I will try to check into the old files I've got from this repository before the big update.

>>> import onewire
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "onewire.py", line 5, in <module>
ImportError: no module named '_onewire'
>>> import ds18x20

Hi,

No, it is not missing, but at a different place. machine.Onewire

You can import machine and create machine.Onewire OR you can : from machine import Onewire

Can you tell me how to paste the lines like you do ?

And, can you close the issue ?

Benoit

I updated the onewire file to match the correct import. I switch the import _onewire as _ow to from machine import Onewire as _ow on line 5 to try to keep compatibility. I re-build and reflash the firmware. I tried the import and everything went well. I stumble upon a new issue while scanning but it may be related to the fact that no onewire device are connected. I will try later with an actual device and open a new issue if needed since it's more related to the implementation now.

To paste the line like I do I use the backtick, 3 of them followed by the keyword bash and I close my quote using 4 backtick. Github - Quoting code

Thanks a lot for the support :+1: !

[loboris]

Sorry for not updating the new Onewire/DS18xx module documentation on time. I'll try to put the complete documentation on Wiki pages later today and tomorrow.

[hargathor]

Hi Loboris and first thanks a lot for your work!

Do you had the time to update the wiki regarding the new Onewire library ? I still have trouble importing and using it.

[loboris]

Sorry, I've been quite bussy during the last week. I expect to finish all the documentation in a next couple of days.

[hargathor]

Any updates ?

[loboris]

Wiki updated
