I am currently trying to control a dot-matrix display using my arduino. The problem is that I don't quite know how to send the right instructions to the display, for example to just show the upper left pixel.
The display has the model name: PS12032LRS-DGB-K01
Link to the datasheet
Maybe someone has already dealt with the display or a type of this display.
I would be very happy about a small code snipped or a detailed explanation. Thanks a lot!

I am building a leaderboard screen in the flutter application, whenever the user comes to the leaderboard screen, I want to show the animation of his old position to a new position in the leaderboard, so I need an animation of this row to go up or down based on his standings, please someone help me which widget to use to get this functionality working. Thanks
AnimatedList is the widget you are looking for. It automatically generates entrance and exit animation when items are added/deleted. Combined that with SizeTransition, and you will get a nice "growing/shrinking" effect.
There are some really good examples (and even a video tutorial) on the official docs as well.
You can also look at this answer for a more complex example of using 2 of them.
I want to be able to determine the size AND rotation of touch contacts for a finger painting app. Right now laying down a long finger diagonally gives me a giant square, which is not what I want at all, I want a long rectangle at an angle.
I figured this would be provided by the system, but even the Surface Pro 4 hardware doesn't have this. But I could extract the info if I had a bitmap of the contact area.
So far googling WM_INPUT related things hasn't helped. Is this even possible?
Edit: a way to get POINTER_TOUCH_INFO::orientation is what I'm looking for, to be precise. My touch screen doesn't put any value into this field.
Edit 2: There's some useful research on this (http://hci.cs.umanitoba.ca/assets/publication_files/2009-UIST-wang-DirectTouchSurface.pdf), all I need now is access to the contact shape.
Edit 3: I got an answer from #msdev, they also suggest motion tracking. The only thing lacking now is continuous tracking, and I guess there's no way to reliably solve that without a contact bitmap. Maybe teaching a neural net could work.
Since Windows 8 there are new messages:
- WM_POINTERUP
- WM_POINTERDOWN
- WM_POINTERUPDATE
I am looking for a way to display the output from a C++ program in a separate window. I am just hoping someone could point me in the right direction. Just running a simple count statement and displaying that on a separate pop up screen would be awesome and I could run with it from there.
To hopefully help clarify a little.. Something similar to this would work http://wwww.youtube.com/watch?v=IXtm7cI21vM
I would like to create a city of top view. For example, something similiar as these images:

I work in adobe Illustrator. Please, how can I do a building of top view? Can I make a building in the perspective view and then rotate to the top view? Or how? Please, if you know about a good tutorial where it is describes, could you send me the link? Thanks.
For the first image, I would go to 3d programs like 3ds Max / sketchup for that effect.
For the second image,
You could use:
- draw some squares
- go to "effect" at the top menu, "3D" - "extrude and bevel"
Hope that helps
Please check that only first image opens.
Its way too easy to do like this. Just hit "M" in illustrator and start making squares and rectangles.
Cheers!
I am working on a game which would take touch gestures as inputs. Now, i would like to display the path/gesture as the user draws it. Can someone please tell me how to do this in cocos2d?
I tried to override the draw method and used ccDrawPoint(). But the point just keeps following the touch. I guess this is because the previous drawing is getting overwritten.
Can you tell me where i am going wrong here or suggest a better way to implement this?
i found a solution with CCRenderTexture sample test in cocos2d. Though i could not find enough documentation on it, but the sample code is enough for a start.
