Instead of filtering out all the available/connected devices every time it would be good to have a method that returns all the devices of a specific type and get the first available device from a type.

Something like:

// List all available motion sensors
DeviceManager.listMotionSensors()
.then((devices) => {
  console.log(devices.lenght, 'motion sensors were found')
});
// Get first available motion sensor
DeviceManager.getMotionSensor()
.then((msk) => {
  console.log('motion sensor found');
});

# List all available motion sensors
devices = list_motion_sensors()
#  Get first available motion sensor
msk = get_motion_sensor()

Trying to connect to the Pixel kit and use the example_list_connected_devices.py script. The script is functioning properly, but is unable to detect the Pixel kit itself.

Found 0 devices Found 0 Motion Sensor Kits Found 0 Pixel Kits

I'm assuming that there's some physical settings on the device that must be set to expose it for control from the serial port properly but I've been unable to find them.

If anyone's got the cheat sheet please post.

• Yes - I've forked the WIKI and will document and submit PR when I figure this out. :)

Hey team. How's it going?
Just wondering it was a while ago - Hardware SDK (coming soon).
Do you happen to know when?
Cheers.

Both MotionSensorKit and RetailPixelKit have a connect() method but no close() or disconnect() which makes the applications hang until keyboard interrupt.

Keyboard interrupt (and similar program exits, eg. sys.exit()) don't close the port connection, so leave terminals (windows) in limbo.
(Currently working round by changing approach to make serialdevice compatible with 'with' command (Can submit a pull request) but it then requires an explict while loop)

hi,

I create a pypi repo(mirror from community-sdk) : https://pypi.org/project/kano-community-sdk/

It is easier to install it: pip install kano-commnity-sdk rather than git clone

and the same usage:

from communitysdk import list_connected_devices, MotionSensorKit

Hello,

I'm loving the Harry Potter wand but I was wondering whether you could tell me if there is a way to write the wand's x and y position to a csv file so that I can keep a record of the wand's movements?

Many thanks!

Is there anyway to export our Python code to the Pixel Kit instead of having to run it from our computer every time? If this is not possible with Python, can this be accomplished with the Javascript version? I saw #13 but didn't find it super clear.

Thanks in advance.

Trying to connect Pixel kit to Window 10 machine. Device Manager shows the Pixel kit as FT231X USB UART for which there are no drivers available. Doing a little digging, it appears I should be installign drivers for the Ftdi chip from here.
https://www.ftdichip.com/Drivers/VCP.htm

Can anyone confirm if this is accurate or if there's another method I should be using for loading the drivers?
[update] I was able to successfully install the drivers above and Windows 10 now sees the device as a "USB Serial Converter"

thanks!

Having issues with pixel python code status methods on pixel class object. In the example below you can see that I have an object of <class 'communitysdk.retailpixelkit.RetailPixelKitSerial'> that is in a connected state. I used the connect_to_wifi method to ensure that it was connected and response suggests that it worked as I'm getting a valid IP address for this network.

When I run the .get_wifi_status method on this object. I get the error below. This is consistent with the get_battery function as well.

my_pixel.connect()
my_pixel.is_connected
True

@murilopolese - looking at your other 2 issues here and there.
You're running into the complication of programming specific issues -- like dealing with Python thread
out of main function, and direct port of NodeJS / Python websocket implementation on language level.

Here's my suggestion to use a platform-neutral and programming language-neutral solution:

• gRPC is a platform-neutral and programming language-neutral mechanism;
• gRPC communication, using definition file, we can generate both server/client language specific library;
• it can be much faster than http/2 with JSON, some benchmark from etcd;
• you're already using RPC;

Rather than giving you a solution on your issues, I have created a simple Proof of Concept to demonstrate how this can work and potentially eliminate a lot of similar issues you might have in future.

Let's dicuss :-)

Can't get event loop from inside a coroutine, apparently. I have no idea how to fix this and it's probably because I should be doing this in a different way.

This code:

from communitysdk import list_connected_devices, MotionSensorKit
msk = None
devices = list_connected_devices()
if len(devices):
    if isinstance(devices[0], MotionSensorKit):
        msk = devices[0]
        def on_proximity(p):
            if p > 200:
                try:
                    msk.set_mode('proximity')
                except Exception as e:
                    print(e)
            else:
                print('proximity', p)
        def on_gesture(g):
            if g == 'up':
                try:
                    msk.set_mode('proximity')
                except Exception as e:
                    print(e)
            else:
                print('gesture', g)
        msk.on_proximity = on_proximity
        msk.on_gesture = on_gesture
else:
    print('there is no device connected')

Prints There is no current event loop in thread 'ThreadPoolExecutor-0_0'. when I swipe up on Motion Sensor.

I am fairly fluent in unity C#, and i'd like to see what i could make with the motion sensor.

(edit: i hope this is the right place to put this? sorry if it isnt)

It's tripped me up before so I knew what to do:

xcode-select --install

This probably happens to lots of people, I think it'd be worth mentioning in the installation guide.
https://github.com/KanoComputing/community-sdk/wiki/Installation-Guides

RIght now only a RetailPixelKitSerial is implemented but the Pixel Kit offers the same RPC protocol over websocket. The Nodejs SDK has it implemented already but the Python SDK still lacks it.

Hi,
I'm trying to send some javascript code to the kickstarter pixel kit.
Ideally I'd like to send code like this:

global.when('start', function () {
  devices.get('lightboard').turnOn({
    type: 'single',
    x: 1 - 1,
    y: 1 - 1
  }, '#4CAF50');
}); 

When I export the "app" from the desktop application I get a .kcode file which is a json file. In this file I can see ".code.snapshot.javascript". If I change that content and import again nothing works... Is there a way I can auto generate the block part from the javascript I just generated? Or simply just push the javascript code?

Thanks,
Daniel

Hi,

I would like to know you you have any code available to exploit the wand.
The idea is to use the wand as main interface to interact with different object controlled by a Raspberry like light or motors for exemple.

Did you have any code available or did you plan to give some access ?

Best regards,
Florian Meyer

I'm using the mu editor, trying to run a one of the routines in the sdk. I keep getting a "no module communitysdk" message. Where should I put the sdk relative to the mu editor's directories?

Hi, are the specs or any of the code for the original Kickstarter "Powerup Kit" available?

I'm happy I can still download the OS, but I'm curious about hacking on the board. I took my old Pi 1 and made it into a Pi-Hole, and it'd be neat if I could plugin in the LED board and have it light up as ads get blocked.

Thanks!

Currently the Python SDK isn't packaged in a way that allows it to be imported as a module. I am very happy to help with this but there are a few issues, most important (at the moment) the name!

As I know already, @malminhas was excited to see a library with an import kano or from kano import motionsensorkit) etc. I think that's exciting and it would make sense from a user perspective.

To achieve this, it would mean that the base folder name communitysdk should be renamed to kano. I don't believe that would interefere in any way with the KANO OS (in my knowledge the only place where a similar Python KANO library exists) as:

• The target group is completely different. No user of the KANO OS, would experiment with our libraries as they are very closed and specific
• The current libraries don't support Python 3 (Only <= Python 2.7)

If people agree on that, I can offer the PR fixing the issue, by creating a Python Package following the Packaging Guide (which can easily be converted in a future Native Debian Package that would be able to be included in the main Debian OS as well, and so to reach literally everybody who owns a Debian (and Debian-based including Ubuntu, Kali, PureOS, Raspbian).

What people think? @murilopolese @malminhas @russormes

I got "example_pixel_kit_stream_frame.py" running. It would be helpful to know what the six digit hex codes are for the possible colors of the leds.

In both implementations for "streaming frame" (python and nodejs), what the communitysdk does is to encode and send a list of 128 color values: One for each LED.

This list is a one dimensional representation of a two dimensional matrix of LEDs so to set the color of an LED by the x and y coordinate we need to convert a pair of coordinates (x, y) into an index in the unidimensional list.

The math is not complicated, for example if you want to set this color to red (#ff0000) all you have to do is to set a value in the frame array:

index = (x * 16) + y
frame[index] = '#ff0000'
# stream frame here

It would be great to have a method inside the communitysdk to solve this issue and/or an example on how to do this calculation.

Hey.
Does someone help with methods?
While Kanno motion sensor desktop app, you have an access to methods that manipulate DOM, or at least have an access to events (for example setting canvas background, etc.).
Are those available with community-sdk?
At The moment we can print in node.js console proximity status and gesture. I was not able to access any of methods available while running Kano desktop app for proximity sensor through local development using provided example code. Could you please help.
Thank you in advance.
