Hi
Is there documentation how to add and interface custom blocks on SNAP?
We have Embedded Linux board which runs SNAP https://www.olimex.com/Products/OLinuXino/A13/A13-OLinuXino-WIFI/ and I would like to add GPIO, SPI, UART, I2C controls as SNAP building blocks.
I probably will do it looking at your code, but if somewhere there is documentation and description how to create and interface custom blocks would help me a lot
Thanks!

Hi,

I am writing an article on using the Snap! to program with the Raspberry Pi's GPIOs. I have borrowed heavily from your code, so I owe you some hearty thanks for that. If you would like to take a look, my stuff is at

https://github.com/pbrown66/snap-RPi

I am not a very good programmer, so if you would like to contribute or make it yours, please feel free. I will not have much time to pursue this after publishing the article. Besides, it is more a proof of concept for me.

Cheers

Paul

P.S.: I tried to contact you via your blog, but I kept getting a 404 error when I tried to post a comment.

Is there any plan for supporting the EV3 LEGO generation?

Instructions say to run python snap.py however can only find Snap-NXT.py which throws the following error (when run with python2, as Python 3 throws syntax errors):

Snap-NXT by Technoboy10 Traceback (most recent call last): File "Snap-NXT.py", line 126, in <module> import nxt.bluesock File "/usr/lib/python2.7/site-packages/nxt/bluesock.py", line 18, in <module> import lightblueglue as bluetooth File "/usr/lib/python2.7/site-packages/nxt/lightblueglue.py", line 17, in <module> import lightblue ImportError: No module named lightblue

I'm on Arch Linux, all up to date. Have both Python 2.7.18 and Python 3.8.3

I just cloned the repo, is there somewhere else I can get the snap.py file

Hi, I'm trying to play with snap-nxt, but I'm not sure if I do the correct things:
After run "python Snap-NXT.py" a message with a URI is shown. Then I open my browser, paste the URI and Snap is ready. I go to "Variables" category and I can see new blocks.
Then I drag and drop a head "When green flag clicked" and a "move motor a 360 degrees" block. And finally I click the green flag. But nothing happends.
The output in the terminal is this:

Exception happened during processing of request from ('127.0.0.1', 51595)

What might be the problem?

Thanks in advance.

Chrome have Serial API now, this would make it easier SNAP to talk to hardware instead of these slow python web servers http://olimex.wordpress.com/2013/06/06/chrome-serial-api-yahoooo/
