My STM32F4 discovery has an accelerometer lis302dl on top. In the demonstration project, ST's engineers used the sensor to do a very admirable thing: to solve the development Board posture. When the development Board is tilted, the top led is lit and the other LEDs are not lit. At the same time, the Development Board will be virtual into a mouse when the board is connected to the computer with a microUSB cable. When you tilt the Development Board, the

Two, listen to whether the current test item is a accelerometer measurement test itemIn the first way, we can get the currently active activity similar to listening to the CTS test current test item. But because it is listening to all the activity in the Android system, it greatly reduces the performance of the system, so there is a more efficient way to pinpoint the test items currently being tested by the CTS without significant impact on the system

Required device capabilities Key Use Telephony Applications require the phone app or use Tel://url Wifi Applications require local 802.11-based network access. If iOS must maintain the Wi-Fi connection while the application is running, you can add Uirequirespersistentwifi as the top-level property list key Sms Applications need to messages applications or use Sms://url Stil-camera The application requ

. When Idletimerdisabled=yes, the "Idle Time Forbidden" State is not turned on and the screen is not locked. You need to be cautious about turning on this setting, which will make your app consume less power.· -OpenURL: Method. You can open some of the built-in iOS apps, including opening your browser, opening Google Maps, making calls, sending text messages, and sending e-mails.2.UIAccelerometerThe Singleton class, Uiaccelerometer, is also mentioned earlier, which accesses the gravity

the following code: [cpp]-(void) Viewwillappear: (BOOL) animated {[super Viewwillappear:yes]; } -( void) Viewwillappear: (BOOL) Animated{[super viewwillappear:yes]; ... ...} The Viewdidload method is called only once when the application is running, and the above 4 methods can be repeatedly called several times, they are widely used but also have a strong skill. For example, some applications use a gravity accelerometer, which constantly polls the

In iOS, the event Uievent class indicates that when an event occurs, the system collects related event information, creates an Uievent object, and finally forwards the event to the Application object (uiapplication). In daily life, there are three main types of events: Touch events, accelerometer events, and remote control events. Here is an official picture:When a user triggers an event by doing so, the corresponding event object is added to the UIAp

differently from the sensors available on basic sensors or devices. For example, the getresolution and getmaximumrange () methods can be used to obtain the sensor's recognition rate and maximum measurement range, and the getpower method can also be used to obtain the power requirements of the sensor. Two public methods are particularly useful if you want to optimize your applications for sensors of different manufacturers or for sensors of different versions. For example, if your application ne

Design of the dual-axis accelerometer ADXL202 IntroductionADXL202 is a dual-axis acceleration measurement system developed by ADI. It simulates input and can measure dynamic and static acceleration. The measurement range is ± (2 ~ 10) g, the output is the cycle adjustable Pulse WidthModulated signals can be directly connected to single-chip microcomputer or counter. The LPC2103 is a phillips family of microcontroller. It is mainly used for industrial
