capacitive trackpad

There are many reasons for the phone screen failure, we can eliminate from all aspects, the following small series and everyone to see. Capacitance screen failure is because the surface of the local charge, popular speaking is what everyone said with static electricity, leading to the inability to determine whether there are fingers or other conductors (such as the capacitor pen) on the top. Put in the pockets of friction, often with vigorously press, screen with dust, hand sweat more or dry in

Apple released this month's 13-inch Retina MacBook Pro, in addition to upgrading the internal main configuration, but also added a new Force touch trackpad, so there is still a need to disassemble again, let everyone see the new Force touch under the hidden secrets. If you want to learn about the performance of the new 13-inch Retina MacBook Pro, you can view our review articles. But if you like to appreciate the unique beauty

）： In PE and other CD-ROM boot environment, the performance of the trackpad if there is discomfort, do not consider as a failure, please install the latest version of the touch plate driven by the pre-installed system to confirm. 5-Key trackpad in addition to the Touchpad Touch Board mode, there are TrackPoint mode, can be used with pointing rod small red Hat to implement the mouse key and screen s

Hardware environment for game music production Text/figure: Xiaoxu game music production room (www.game1234567.com) Game music design also belongs to the major category of music production. Some of the required hardware and software environments are not much different from those of professional music production rooms. Some commonly used hardware devices in the "Xiao Xu music production room" mainly include: audio interface, synthesizer, listening speaker,

Abstract: The successive approximation register type (SAR) ADC occupies most of the medium to high resolution ADC market. The sar adc has a maximum sampling rate of 5 MSPs and a resolution of 8 to 18 bits. The SAR architecture allows high-performance, low-power ADC to use small-size packages and is suitable for systems with strict size requirements. This article describes how sar adc works and converts input signals using a binary search algorithm. This article also provides the core architectur

Each device is equipped with a Capacitive Probe that inspires a pin and picks up signals from the Capacitive Probe.: 1. On

Design of I2C-based embedded multi-point touch screen driver Abstract: With Samsung's 7958 processor, the driver Management System of Embedded Linux is used to implement the design of multi-point touch screen Driver Based on I2C bus protocol, such as cypress and snaptics tm1444. Practice has proved that the qtopia Platform Based on Linux core and the andriod embedded operating system run smoothly, with a high degree of recognition and accuracy. Introduction With the development and promotion of

Trackpad is probably the coolest and most attractive part for PC users. It is no exaggeration to say that when you use the MacBook Pro for several hours and then return to the PC, you will be very depressed. The no-button design is the first feature, and the entire trackpad is a big button. You can click the button wherever you move it, instead of just making a model knock on the panel (of course, it can a

following shows how to set the lower-left corner of the screen to a screensaver. When you need to leave your seat, simply swipe the mouse (or touch trackpad) to the lower-left corner of the screen to turn on the screensaver feature.Then set the corresponding lock screen delay time in the privacy permission, ensure that the MAC needs to enter the login password to use when waking up.3. Set the right mouse buttonUsing the mouse under the MAC system, th

Apple today updated its keyboard, trackpad and mouse products to provide a better experience than previous products. So what about the new Apple mouse, keyboard, and touch version of the product? How much is the price of these three new products? The following triple small series for everyone to bring Apple released three of peripheral accessories products detailed evaluation. In addition to the battery changes, the new product has also been cha

prevent Alienware 14 from being a distinctive notebook product. The design of Alienware 14 is similar to the overall style of previous generations, but it also adds more facets and edges, and looks more sedate and sophisticated. After opening the notebook lid, whether it is the texture of the keyboard panel, the Gap, the keyboard, trackpad or the bottom of the glow bar, after the operation is really like an alien working equipment, the future is ful

Capacitive, resistive, infrared ...... Although readers may have used to draw their fingers on the screen, I was surprised to know that there was such a screen that could be operated by touch? Now, let's take a look at the characteristics of various touch screens, and what limitations exist at the same time. The Representative Models of the resistive touch screen are Samsung Messager touch and HTC Touch diamond. This screen is made up of Multilayer

 How to prevent the amplification circuit self-excitation?Personal experience, the most effective way:1. Is the resistance of the amplifying circuit too large? For example, I've seen a circuit that amplifies 10 times times, and the resistor chooses 100k,1m. (Even the textbook is written). Intrinsic circuit current is too small, anti-jamming ability is weak, the output signal is more easily coupled in.2, the output line is too long, not only easy self-excitation, and the signal is also suscepti
