This document describes how to develop an I2C interface touch screen driver mounted on the friendly mini-2440 platform. Kernel edition linux-2.6.32.2,The platform is a touch screen with the arm9-s3c2440 + I2C interface. For exampleLinux I2C driver architectureDescriptionHttp://www.lupaworld.com/273398/viewspace-204237.html To mount a new I2C device, you need to implement three parts: 1) adapter hardware driver:The kernel has implemented the mini2440, I2C Adapter Driver, you can see the r

If your computer is not only a screen, but also has a screen or a projector, then with the help of the Win8.1 system, your computer can use dual-screen operation, can also be used for projection, you can use this technology to share your computer operation, show slide show, Even play your favorite game on a bigger screen. So how do you connect an extra projector or monitor for Win8.1? Let's take a look. Win8.1 How to connect an extra projector or monitor You can use DVI, VGA, or HDMI cables to

Having a second screen can help you view multiple open applications at the same time. You can also connect the projector so that everyone in the room can see your screen. You can use a DVI, VGA, or HDMI cable to connect most monitors and projectors. (Some devices can even connect wirelessly.) For information, see projecting to a wireless monitor using Miracast. Your computer may have one or more of the following ports. DVI, VGA, and HDMI ports After you connect a monitor or projector to your

JS touch events, generally used to move the end of the touchscreen slide Copy Code code as follows: $ (function () {Document.addeventlistener ("Touchmove", _touch, False);}) function _touch (event) {alert (1);} Touchstart: Triggers when the finger touches the screen, even if a finger is already on the screen.Touchmove: A continuous trigger when the finger slides on the screen. During this event, calling Preventdefault () prevent

mobile PC industry, which seems to be related to the first laptop manufacturer, such as the glasses-free 3D, ultra-thin, and 21:9-a revolutionary vocabulary that comes from Toshiba. The same is true in the ultra-thin camp, although the retina display's Apple MacBook Pro and Google's Chromebook pixel seem louder, despite the name tolerance, but these two products are not actually affiliated with the Windows camp. In this case, Toshiba has surprisingly released the new ultra-polar product--kirab

Android provides support for two gesture behaviors:1, for the first gesture behavior, Android provides gesture detection, and for gesture detection provides a corresponding listener.2, for the second gesture behavior, Android allows developers to add gestures, and provide the appropriate API to identify user gestures.Gesturedetector.ongesturelistener is a listener that is responsible for providing the user with the gesture behavior.Boolean Ondown (Motionevent e): Triggers the method when the tou

Throw (onfling): The finger moves quickly on the touchscreen and releases the action. Long Press (onlongpress): The finger is pressed for a period of time and is not loosened.

I2C pin. the I2C of the development board itself has a K pull-up resistor, so no external pull-up resistor is needed. 3) connect the gpio_9 of the development board to the int port of the chip to control interruption. 4) A gpio is required to control the reset of the chip, but the gpio foot of the touch screen interface of the Development Board has only one gpio_9. Therefore, find another gpio foot to control the reset. The connection method is as follows: 1 vcc33 => 3.3 V 2 Gnd => ground 3 S
