The example in this section is a tilt angle measurement application that accurately measures the tilt angle of your phone and the horizontal plane, using the acceleration sensor inside the Android sensor. The physical meaning represented by the various values of the accelerometer, coupled with a very simple algorithm, can be used to measure the tilt angle.The angle value is displayed exactly as the phone tilts and the effectNot much nonsense to say di

Recently engaged in a project related to the accelerometer, so contact with more sensors, now write a summary, to prevent the later and I like to walk so many detours.The first thing to see is the pin graph, if the driver should not first troubleshoot the hardware problem:SPI Connection methodIIc Connection method We then focus on a few registers: sensor Name (read/write) Register number function Chipid (R) 0x0

The coordinate system of the Android sensor is not the same as its 2D design, with coordinate systems such as:Once the sensor listener is registered with the Sensormanager object, an object of sensorevent can be obtained within the Onsensorchanged method.The Sensorevent object has an important member variable public final float[] values, which are defined as follows:Public final float[] valuesThe length and contents of the values array depends on which sensor type is being monitoredIf the regist

messy pages quickly change to simple text As the content of the Web page is formatted according to a certain format, and we do text conversion only need plain text files, so first of all, we need to collate the information on the Web page. First,

The number above one thousand can be formatted as 1 K. For example, 1320 is converted to 13200 K or to. This plug-in has not been found for a long time on the Internet, which of the following experts can tell me where to find the plug-in or what the

"Java in a nutshell:a Desktop Quick Reference, 2nd edition"Author: David FlanaganPublisher: O ' Reilly & ASSOCPublication date: 1997Introduction: A brief summary of the Java 1.1 online documentation. Personally, I prefer to read documents online,

Python books have begun to steadily occupy a larger share of bookstore bookshelf space. Since I began to publish these reviews, the number of books on Python that can now be called "scrap" may already be four times times the size of the original.

Before you start Since the publication of my recent book Digest nine months ago, there have been some new Python books published, and other books that I didn't have a chance to comment on were sent to my desk. I don't have a chance to comment on

Since Andorid does not recommend the use of conventional directional sensors, it is recommended to use accelerometers and geomagnetic sensors to construct the data of the direction sensor, in fact the rotation angle of the z axis is the code example

This post is translated from the IMU (accelerometer and Gyroscope devices) guide used in embedded applications.This article mainly introduces the mathematical models and basic algorithms of accelerometers and gyroscopes, and how to fuse the two, focusing on the discussion of algorithms and ideas.IntroducedThe purpose of this guide is to introduce inertial MEMS sensors, especially accelerometers and gyroscopes, and other integrated IMU (inertial measur
