Problem with Digital input/outputs iot 2040 #166

Open soportekenai opened 3 years ago

soportekenai commented 3 years ago

Hi, I have an iot2040 with the iot2000 input/output module. I use the analog current inputs to take sensor readings, this works great.

Also I use digital inputs to read activate buttons and outputs to activate relays, with the followings problems:

We have realized that sometimes after a certain time or when we do some deploy in NodeRed, we begin to have problems with the digital in/outputs. They stop working

It also happens to us with the user led, the red led works but no the green led

Now i am activating the digital outputs by running a python from node-red but it is a problem -> time delay, digital input not work...

I use official SD image Siemens: -NodeRed 0.20.7v -node-red-node-intel-gpio 1.0.0-iot2000

Thanks

Maybe the same issue as in https://github.com/siemens/meta-iot2050/issues/57. We fixed it for the 2050, but we did not backport this pattern yet.

Can you describe the error in more details? Does node-red report anything in the log? Does restarting node-red resolve the problem? Or only rebooting the box?

soportekenai commented 3 years ago

I only use intel gpio module in node red. because node-red-contrib-iot2000 hasn't got modules to use digital outputs and analog inputs.

Node-red log doesn't show no mistake.

The problem is resolved when restarting node-red (sometimes) or rebooting the box

jan-kiszka commented 3 years ago

I do not mean node-red-contrib-iot2000. I'm always referring to the node-red-nodes-intel-gpio as they are delivered (i.e. ...1.0.0-iot2000) by meta-iot2000 and our example image.

Let me see if I can easily port the fixes we made for meta-iot2050 also to meta-io2000.

soportekenai commented 3 years ago

Thank you very much, I await your news

jan-kiszka commented 3 years ago

I've pushed https://github.com/siemens/meta-iot2000/commits/jan/mraa-node-gpio-update, but it is only build-tested so far. As patches from the IOT2050 applied rather smoothly, it should work, though.

jan-kiszka commented 3 years ago

Now also tested, and it appears to work fine.

soportekenai commented 3 years ago

Perfect, thank you very much. Let's try it and I'll tell you

soportekenai commented 3 years ago

I need your help because I am not sure how to make the changes on my device

jan-kiszka commented 3 years ago

You will need to rebuild an image from my branch - or port the commits to your version of meta-iot2000. But there is no way around (re)building an image from sources.

soportekenai commented 3 years ago

Sorry for my ignorance, but I don't know how to make these changes on my iot2040. We downloaded the OS image but I don't know how to rebuild an image from your branch or port the commits to my version of meta-iot2000. Can I modify the files directly? Thanks

jan-kiszka commented 3 years ago

You could edit the nodes, but you also need a recompiled libmraa. So, have a look at the README that comes with this repo and try to follow the build instructions, either on a supported Linux distro or inside the docker container.

soportekenai commented 3 years ago

Hi,

We are trying to follow the steps to build the image but we cannot do it.

We need a solution to this problem, we need you to explicitly attach the steps to follow or send us the image already created. Excuse me for my ignorance

First, install docker or podman on your Linux machine/VM. Make sure you can use it as the logged-in user.

Then:

git clone https://github.com/siemens/meta-iot2000
cd meta-iot2000
git checkout jan/mraa-node-gpio-update
wget https://raw.githubusercontent.com/siemens/kas/2.4/kas-container
chmod a+x kas-container
./kas-container build kas-example.yml

That said, understanding what went wrong with using kas natively (without a container) would be nice as well. How did you install it? On which distribution/version did you do that?

soportekenai commented 3 years ago

I have created a Linux 16.04 LTS VM with docker I have followed your instructions but it gave me error 1 1

I have followed the link below to try to solve https://docs.docker.com/engine/install/linux-postinstall/

But I get the following error 2 2

I have followed the link below to try to solve https://www.digitalocean.com/community/questions/how-to-fix-docker-got-permission-denied-while-trying-to-connect-to-the-docker-daemon-socket

But I get the following error 3 3

Wouldn't it be easier for you to generate the image and send me a wetransfer or similar?

jan-kiszka commented 3 years ago

Please see https://support.industry.siemens.com/tf/ww/en/posts/how-to-build-github-example-image/237116/?page=0&pageSize=10, steps 1-6, for setting up a suitable build VM (not only for the IOT2050).

Regarding a prebuilt image, please contact our support directly.
