I'm in real trouble in terms of jitter-avr serial communication at the moment.

(I'm new for the jitter.... everything comes to me as a whole new world...)

in short. I'm gonna get the video data from web cam and will pixelize that and send the data(of each of pixels)

to servo motors via serial communication and avr.

But have no idea about how to read the each pixel's data and how can I send that value to avr via serial commuication. (I mean what should i do for coding? I'm gonna use max/msp/jitter)

For better understanding about my prob, I attached jpg file with screen shot.

Every single quick answer will be my great life saver!!!

no idea about serial communication, but to read matrix values have a look at jit.spill or jit.iter. I made a quick little example that shows you how to retrieve the coordinates of each ON pixel.

edit: just noticed in your pic that you are on a windows machine. you will need to change the jit.qt.grab to jit.dx.grab. rest should work fine.

If I want to separate each of pixel value per pixel coordinate (x,y), then what should I do?

I mean I'm gonna install around 200 units of motor and will install like matrix (which is matched with pixel matrix of camera)

And if cam get the ON pixel data, then I will activate motors which is located at ON pixel coordinate point.

To do that, I might need to separate the values per each coordinates of pixel.

but jitter is still bit vague for me... so please kindly let me know about it~~~!

Can I add one more quick question? ;0

In this case... what should I do..?

Somehow this is quite obvious question..

have a closer look at the jit.iter object. it gives a pixel by pixel list of values AND reports its location. I just put all the ON pixels in a list to make a point. If you get rid of everything below the jit.iter object you should be good to go. the middle outlet reports the location in the matrix and the left outlet reports the value of that location. should be easy enough to get logic going you described above. if you need help post a patch with an attempt and I will have a look.

Please help me to jitter(web cam data in-pixelized data) to avr serial communica
