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 micr

Acceleration Sensor Accelerometer The Android system supports powerful management services for sensors. The steps for developing sensor applications are as follows: (1) Call the getSystemService (Context. SENSOR_SERVICE) method of Context to obtain the Sensor Manager object. The SensorManager object represents the syst

Android acceleration sensor simulated shake effect-android learning Tour (66)This article mainly introduces the simple usage of android acceleration sensors. It simulates shaking. If the acceleration speed in the three directions of x, y, and z exceeds 15, the Toast will pop up, of course, you can set more complex poli

Let's take a look at the simulation of the shaking function, we are based on the mobile phone accelerometer to achieve this function, the implementation of the method is relatively simple.Mainactivity.java:Mainactivity.java: Packagecom.location.activity;Importandroid.app.Activity;ImportAndroid.content.Context;ImportAndroid.hardware.Sensor;ImportAndroid.hardware.SensorEvent;ImportAndroid.hardware.SensorEventListener;ImportAndroid.hardware.SensorManager;ImportAndroid.os.Bundle;ImportAndroid.widget

First of all, the gyroscope sensor needs to be debugged in the real machine environment, the PC end has no effect.1. Get the SensorThe devicemotion event is monitored on the window, and the accelerationincludinggravity (built-in gravitational acceleration sensor) object is obtained through the event object. The code is as follows:function (e) { var motion

; /** (3) drawing view canvas paint ondraw The android plotting operation inherits the viewImplementation, in ondrawFunction. The invalidate and postinvalidate methods are used to refresh the interface.After the two methods are called, The ondraw event is called to re-paint the interface. The following code creates and updates the game interface. gametick () re-assigns a value to the drawing parameter based on the coordinate value obtained by the accelerometer. @ Override (4) display custom

Tilt sensor: Human Motion Description is actually a series of related angle calculation processes, there is no relative displacement and scaling between the bones, so the acquisition of human motion, only the angle is necessary. Currently, motion capturing instruments use optical recognition methods for capturing. If you can use a tilt sensor to capture data, it may be better. The following is an overvi

When using an accelerometer, pay attention to the following points: First, make sure that your IIC is correct; Second, you must first calibration the system. The calibration method is as follows: Flat 7455 to ensure that the Z axis is down. If the system is OK, the X axis output is 0, and the Y axis output is 0, the Z-axis output is about 63. If the number of workers is not above, the following adjustments should be made: When the scalar value is smaller than the actual value, a 2 * error va
