Arduino is reading the needle encoders fine. It's sending all values to Processing, but Processing is missing some of those values. I think it's due to this:

https://github.com/mcanet/knitic/blob/master/protoAppKnitic_p5/serial_comunication.pde#L61-63

This can spend a lot of time inside the while loop and miss some values. Or maybe it's because of some other delay.

Either way, if you can take a look at this code and suggest some changes. Don't worry about implementing them, we'll do it here on my branch. I just wanted to start a discussion here : )

I'm using a MacBookPro 2.7GHz Intel Core i7 8Gb 1333 MHz DDR3 RAM using OS X 10.9.5. with an Arduino compatible OSEPP Uno R3 Plus.

I've downloaded the Arduino Application and am able to connect and power the board.

I've downloaded the latest Knitic software version from Github, yet every time I've attempted to open/install the software it gives the following error message . . . Please help.

It is kind internal bug from processing, describe here:
https://code.google.com/p/processing/issues/detail?can=2&start=0&num=100&q=&colspec=Stars%20ID%20Type%20Status%20Priority%20Owner%20Summary&groupby=&sort=&id=541

It will be nice to solve some how.

Thanks for your new Arduino testing sketcheses and last releases of the Processing & Arduino soft. We did tests on solenoids and sensors and it looks good. But still having problems with pixels. Not all the needles that should knit are knitting.

The Processing sketch works well without knitting pattern.
Right and left sensors are ok.
Stitches position is looking good.
But when I load a picture (PNG or JPG) the soft jumps many rows at any carriage action.
Any idea?

It is strange it is working in processing and not in Openframeworks.

http://www.knitic.com/ seems broken

I only get a blank page (tested both on firefox and safari)

I was looking for info on how to use and attach this, why you need the PCB's provided here, some examples on what it can do, the supported hardware (I only see KH930 and KH940) etc. All this info seems not available here.

I'm very interested building a knitting machine by my own and searching for some open source projects which I can use as a starting point or to find a community.

Can someone lead me to active projects for (open source) knitting machines? Im spacially interested in knitting motif socks.

Add code to remember when the last Arduino communication was received. If it was more than N milliseconds ago, change connection status.
