Could I send an image or video from Arduino IDE to Touch Designer software?
Could I use the pictures saved with the CMOS camera for example?
Thanks,
Giuseppe
You can send images via bluetooth, wifi or serial, but the speed of taking the picture and sending over wont be that fast.
You are better of with a gopro connected via wifi or Canon via usb cable. Forget Arduino if you need a live feed.

I am trying to take photos while the camera is connected to the computer. As soon as the camera is connected to to PC the camera changes it's mode to busy. I would like trigger the camera to take picture while it is connected to the computer.
You can use the EdsSendStatusCommand function with kEdsCameraStatusCommand _UIUnLock to use the camera manually while plugged in. Note that some commands issued with the Canon SDK may lock the camera UI again.
A. I have a general understanding question about the "still pin" or "snapshot" functionality on some web cameras: how does this work ? It must be one of the following possibilities:
The camera is on and video is streaming to the host. When the snap button is pressed, a signal is sent to the host's camera driver (/dev/input/event0 on linux), the driver extracts a frame from the stream, and sends it up in the stack.
The camera is on and video is streaming (or not) to the host. When the snap button is pressed, the on board firmware puts aside the current frame, and tells the host a new "still" is available.
B. I have 4 usb cameras attached on a R-Pi (single usb host). All cameras have a still pin. I don't care about the video, no need for streaming, I want to take 4 simultaneous photos. My idea is to trigger all 4 cams to capture a frame using the still pin. How can I capture those 4 images without streaming video (bandwidth issues) ?
Note: I have already experimented a lot and I am capable of capturing a frame from a video stream. My cameras are unknown brands but exposes "video capture" as device caps. When using AMCap on windows, the snap button triggers a snapshot.
Thanks for any help.
I am developing app for iPad and i want to send text message(not iMessage) from my app. Is it possible through iPad which has WiFi with Cellular?
No this is not possible, since the iPad does not have any support for SMS. Even Apples own Messages.app does not support SMS on iPad.
You would need to setup an external server that handles sending the actual texts. As for making the app send texts using the iPad's GSM signal it is impossible
I'm working with a Sony DSC-QX100 camera via Sony's Remote Camera api, specifically for use on a Windows 8 tablet (basically replacing the built-in camera of the tablet with this unit). I'm able to consume the camera's LiveView (streaming) and LiveShot (take a picture and retrieve the image from url) features triggered from my application.
My question is whether or not the Remote Camera api exposes any functionality to access pictures stored on the camera's SD card (when it is available). Bottom line, my user may choose to take the picture directly with the camera unit (manually, instead of remotely via my application on the tablet) and I've not yet found the method by which to retrieve this picture from the camera (other than transferring the SD card from camera to pc). Anyone tried this or seen something in the API documentation that I'm missing?
Current Camera Remote API does not provide direct access to SD card.
All available APIs are documented.
What is the best method to transfer file via wifi from one ipad to another?I know how to handle the wifi network connection.But i need to know the most efficient way to transfer imajges , video etc from one ipad to another
You may want to look at https://github.com/robbiehanson/CocoaAsyncSocket - you can use it as a TCP server/client to transfer files between ipads.
I've used it between a laptop and iPad, but it will work iPad to iPad also.
