DHT11 package can not be import in project
floitsch 11/24/2022 09:45 AM
Which package are you using?
Shadi 11/24/2022 09:45 AM
DHT11
floitsch 11/24/2022 09:46 AM
ok.
floitsch 11/24/2022 09:46 AM
Try to:
import DHT11.dht11Shadi 11/24/2022 09:46 AM
ok
floitsch 11/24/2022 09:46 AM
That said: it should actually be
import dht11Shadi 11/24/2022 09:47 AM
But again it does not work
floitsch 11/24/2022 09:48 AM
Can you show me the content of your
package.lockShadi 11/24/2022 09:48 AM
Yes, But I think the problem is related to path where the package has been installed
floitsch 11/24/2022 09:49 AM
We will have a look at that in the next step.

Shadi 11/24/2022 09:51 AM
one question, "package.lock" I created manually
Shadi 11/24/2022 09:51 AM
Is it correct?
floitsch 11/24/2022 09:51 AM
This won't work.
floitsch 11/24/2022 09:51 AM
It's saying that it should find the package dht11 at location ..
floitsch 11/24/2022 09:51 AM
Unless that's where you put it, it won't find it.
floitsch 11/24/2022 09:52 AM
I would remove (or rename) the package.lock file.
floitsch 11/24/2022 09:52 AM
And start over.
floitsch 11/24/2022 09:52 AM
Similarly, if you have a package.yaml file, I would remove/rename it.
floitsch 11/24/2022 09:52 AM
(unless you have important information in it).
Shadi 11/24/2022 09:53 AM
i can remove them, because these files do not contain important information, So, I removed them
floitsch 11/24/2022 09:53 AM
Then start again by writing:
toit pkg init
toit pkg install github.com/nilwes/DHT11floitsch 11/24/2022 09:54 AM
Write these commands in your project folder.

You can also tell

Generally it's easier to just locate yourself into the directory from which you want to work from.

Even easier is to

It works perfectly; thanks a lot. I just have to find what is the problem with my sensor that I get "read error."
floitsch 11/24/2022 09:58 AM
The nilwes package is using polling to read the data.
floitsch 11/24/2022 09:58 AM
Unfortunately that's not super reliable.
floitsch 11/24/2022 09:59 AM
(On v2 we use the RMT hardware peripheral which is more reliable. That would be a different package, though).
floitsch 11/24/2022 09:59 AM
I have used the nilwes package before, and my DHT11 sensors worked with it.
floitsch 11/24/2022 10:00 AM
But if you get read-errors, if might be that the naive approach that is used in the nilwes package isn't good enough.
floitsch 11/24/2022 10:00 AM
That said: obviously start by verifying that the cables are connected correctly.

Shadi 11/24/2022 10:00 AM
can I install new version ?
floitsch 11/24/2022 10:00 AM
(different modules put the vcc/do/gnd onto different pins).
OPShadican I install new version ?
floitsch 11/24/2022 10:01 AM
We recommend to use Jaguar (v2) for all new users.
floitsch 11/24/2022 10:01 AM
It's significantly more up to date.
floitsch 11/24/2022 10:01 AM
It doesn't come with the cloud, though.

floitsch 11/24/2022 10:03 AM
