iphone Programming Glossary: driver

http://stackoverflow.com/questions/10921395/using-accelerometer-to-calculate-speeds

data collection device. What we are trying to accomplish is how much acceleration and more importantly deceleration a driver exerts when exposed to certain prompts. I found this paper that has allot of useful information Accelerometer physics The.. The problem is that we most likely will not have a calibration time to start at zero.. however it is assumed that the driver is starting at 0. We will use GPS positioning to locate the vehicle tracking the time stamped location data we should calculate..

ARM vs Thumb performance on iPhone 3GS, non floating point code

http://stackoverflow.com/questions/1198176/arm-vs-thumb-performance-on-iphone-3gs-non-floating-point-code

the iPhone I hear those folks are using LLVM I like the llvm concept in many ways and am eager to use it as my daily driver when it matures but found it to produce code that was 10 20 or much more slower for the particular task I was doing. I was..

Skybox OpenGL ES iPhone and iPad

http://stackoverflow.com/questions/4110893/skybox-opengl-es-iphone-and-ipad

quite annoying when you're starting making an error generally means your program crashes deep inside the OpenGL driver without giving you a hint as to what you did wrong. It's probably best to build up a bit at a time. In terms of a UIView..

Determining Image Luminance/Brightness

http://stackoverflow.com/questions/4876315/determining-image-luminance-brightness

case you may have to go beyond the image and query the camera. In theory you can do this either directly through a driver unlikely or perhaps by looking at the image metadata e.g. with JPEG there's EXIF . Lastly you haven't said what it is exactly..

ES 1.1's fixed function pipeline. This is backed by Apple's documentation on the PowerVR SGX which says The graphics driver for the PowerVR SGX also implements OpenGL ES 1.1 by efficiently implementing the fixed function pipeline using shaders...

http://stackoverflow.com/questions/6076734/using-iphone-as-control-device-game-controller-type-in-windows

in Windows Is there a way to use the iPhone as an interface device for a computer without actually having to code a driver Being the owner of a sub par game controller and realizing that it would be cheap and a good experience to try to roll my.. and sending them over a network but where would I begin on the Windows side I'd prefer to not get as low level as a driver but I want to be able to use the accelerometer as an analog input device and buttons on the screen as regular buttons. How.. an analog input device and buttons on the screen as regular buttons. How should I go about this If I have to write a driver what would be a good reference code sample to start with iphone windows input driver share improve this question You..
