An important input source on a mobile device is the device direction. Most devices are equipped with an

Cardboard Talk02 Accelerometer

. Although accelerometer accelerometer is an important input device for many software applications, some developers are using the wrong way to manipulate the accelerometer's data. More importantly, these applications do not take into account the direction of the device, which leads directly to a bad user experience. Handling the correct direction of the

iOS Learning note 34-accelerometer and gyroscope

I. INTRODUCTION of COREMOTION FrameworkWe know that there are some iOS apps that have special requirements, such as:1. E-Compass Compass application: Let us know the direction.2. Sport type Software: Let us know how many kilometres we run.3. Shake and shake function in social software.4. Play in the role class in the game according to the device's shaking and so on operation.In fact, they're mostly using a

Principle and application of accelerometer-mobile phone rollover, weightlessness detection, motion detection, position recognition

This paper introduces the characteristic principle and application scenario of the-LIS3DH accelerometer sensor for wearable devices. ST's LIS3DH is widely used in smart wearable products such as smart hand loops and smart step shoes.LIS3DH has two ways of working, one of which is that it has built-in algorithms to handle common scenarios such as standstill detection, motion detection, screen flipping, weightlessness, position recognition, click and do

iOS Development-coremotion Framework (accelerometer and gyroscope)

Coremotion is a framework dedicated to motion, which contains two parts of accelerometers and gyroscopes, before iOS4 the accelerometer is the Uiaccelerometer class responsible for collecting data, Now generally use coremotion to deal with the acceleration process, but because Uiaccelerometer is relatively simple, the same people are used. Accelerometer is determined by three axes, the user's most common op

Onenet Kylin seat Application development: acquisition of accelerometer ADXL345 data

0xa6 write, 0xa7 read.Since the ALT address pin (PIN 12) is grounded in the Kylin seat, the addresses are 0x53, which is 0xa6 write, 0xa7 read. In addition, 2 terminal signals are also introduced into the MCU.3 , Software designThen we started the software design. Since the ADXL345 uses the I²c interface to communicate with the MCU and is connected to the I2C2 (PB10, PB11) port, we will implement this part

Coremotion in-frame accelerometer using a concise tutorial

ObjectiveBefore someone made a mobile phone anti-theft app through the iphone's accelerometer, and it was through this anti-theft app to get Angel investment. From then on gorgeous turn, the company develops the vivid. Although this project is not very good at the end, but it is really a nice idea.Maybe you don't know, every iphone has an accelerometer built in. This allows the built-in

Gyro, accelerometer, magnetometer and other sensors summary (turn)

Transfer from gyroscope is an internal gyroscope, whose axis is always parallel to the initial direction due to the gyro effect, so that the actual direction can be calculated by deviations from the initial direction. The gyroscope in the cell phone is actually a very sophisticated chip with ultra-tiny tops inside.Accelerometers are used to detect the size and direction of the acceleration that the phone is subjected to, while the mobile p

How does the Three-Axis Gyroscope and accelerometer help the iPhone locate

This article is from:,thank you! In June 8 last year, the Great Apple company released the latest iPhone 4G, which has many hardware upgrades. For gamers, the largest "Three-Axis Gyroscope "! The first time I heard that this "Three-Axis Gyroscope" was a time ago, I occasionally found that Apple players were testing the positioning function of the iPod Touch. For details, see "location offset problem of different mobile devices ".It seems very novel-Because iPod touc

Final:Cocos2d-x, the inheritance structure of layer layers:As you can see from the image above:several direct sub-categories of emphasis are: Control, ScrollView, Menu, Layercolorwhere Layercolor can make a layer color the subclass of control, which is all the classes that interact with the user, such as: button, slider, etc.0. Cclayer OverviewA game can have a lot of scenes, each scene may contain more than one layer,The layers here are generally cclayer objects. The cclayer itself has almost n

Principle of accelerometer in IOS

example a delegate to the accelerator, the program example for declaring an example is as follows: UIAccelerometer *accelerometer = [UIAccelerometer sharedAccelerometer]; You can set the update rate of the instance. You can use the following program to set the update rate, which indicates that the update is performed once every 30 seconds. accelerometer.delegate = self;accelerometer.updateInterval = 1.0f / 30.0f ; After setting the delegate, you m

"Arduino Official Tutorial First series" Sample program 6-3 Memsic2125 Accelerometer _arduino

Memsic2125 Acceleration Meter MEMSIC2125 is a two-axis accelerometer that can measure the acceleration of positive or negative 2g in two directions (g represents the gravitational acceleration). Its pin design is simple: Only two data output pins, one for the x axis and one for the Y axis. Its data output pins will output different pulse widths according to the size of the acceleration (do not know what the pulse width is please see this article). The
