When a user taps into a textbox the on focus event calls the Input Panel and resizes the scrolling panel. The problem is that the textbox may be hidden by the Input Panel. Is there a w...
Hi all, we are planning to develop a device controller for a banking machine. This controller would be embedded directly on the machine, the idea is to use an off the shelf ARM board with Linux for this. We would like to provide the API as a RESTful Web Service. Probably we would have to separate the software on the controller in at le...
I am rather new to Linux device driver programmring, but for debugging purposes, I would like to write a stream of data directly to a file. Or maybe I should aks the question differently: I have a system-on-chip, where one module provides a data stream. The module has to be initlized with a write address. Instead of writing the data int...

I'm accessing my memory-mapped device via a device-specific physical memory on the PC. This is done using a driver that maps a specific physical address to a pointer in linear memory on my process address space. I wanted to know if there is any way I can obtain a block the specific physical address and prevent other processes or devices...
The device token that got from APNS is send to the provider. I have two questions on this device token : 1) Whether device token has the expiry time 2) Whether I will get the same device token for each time I call registerForRemoteNotificationTypes in the application launch? We are planning to go for 1:1 mapping between logged in use...
Hi, I have written a dummy (ram disk) block device driver for linux kernel. When the driver is loaded, I can see it as /dev/mybd. I can successfully transfer data onto it using dd command, compare the copied data successfully. The problem is that when I create ext2/3 filesystem on it, I have to use -o loop option with the mount command...
Hi there, I have code running in an iPhone application I am developing. Basically, the code needs to load an images and calls: size_t bitsPerPixel = CGImageGetBitsPerPixel(imageRef); I noticed that on the iPhone simulator this call returns 24 and the device itself it returns 32. Is this behavior by design? Is it somethin...
I've actually got an Windows/Java Question. I've got a plugged-in device which I want to access via Java. Normally you can access an e.g. USB-Stick via the Drive letter... but this tablet is displayed by Windows as a "Portable Device"... which means, that the Path is something like "Computer\Archos 5S" and there is no Drive letter. I ...

Hi all, I have developed my app using core data. It works fine in the simulator. When I deploy it to the device the DB is empty. It is 49k where it should be 484k. Basically it is not populated. Since I don't write to the DB when the app is running I need to provide a populated DB to the App. So I copied the populated DB from th...
Hello, I'm trying to write/read to an extern device connected to a FTDIchip FT2232 MPSSE mode using SPI. I'm using the SPI function given by FTDI for Labview. I'm doing this: Open_Device - Init_Device - Write/Read - Close_Device The problem is that I don't have a clock signal on the scope when I try to read/write. Do you have a solut...
I'd like to capture signatures of application users with a mini-tablet/little pos signature device. I welcome any first hand experiences of which ones were good and which ones to stay away from. Off the top of my head I can think of a few features I'd like to see: USB interface Not too expensive (I don't know 100-200 dollars?) Be eas...
Good Morning, I got my app to install on the Backflip and started testing it. On the emulator everything appeared ok but on the Backflip there are a few notable differences. I have edittext boxes which on the emulator automatically vary in size to accommodate the text. The text is a number, the max being two digits, i.e., 1-99. On t...

So I need a program that would open the serial port and accept multiple TCP connections like: class Program { public static void Main(string[] args...
