I just followed the video to learn the operation examples of sensors in Android, and made a very simple compass application using the direction sensor... Sensor functions are rarely used in work projects, so many of them don't know. Now I want to learn more about it as a step-by-step approach... First paste the software for final operation The image material used in it is a temporary PPT. It is very simple and can be used. This is not the point. The

Steps:(1) first, mem3280 is an I2C device, so the first step is to check the chip spec and determine its I2C address (0x30)(2) After the address is determined, add I2C device information in the kernel/ARCH/ARM/mach-vc0882/board-vortex.c file:1212 static struct i2c_board_info i2c_devs1 [] = {1213 # ifdef config_sensor_ssz03041214 {i2c_board_info ("ssz0304-sensor", 0x55 ),},1215 # endif1216 # ifdef config_sensor_mmc32801217 {i2c_board_info ("mmc3280-sensor", 0x30 ),},1218 # endif..................

measurement mode, single measurement I used a bit, not very good, so the following main introduction of continuous measurement. Configuration as a continuous measurement is simple, is the above mode register, address 0x02 As you can see, configuring a continuous measurement mode requires only writing the mode register to 0x00. Configuration to continuous, configured as sequential read mode there is a very important place to remember: read XYZ, must read 6 bytes at a time, that is, all r

In the project using real-time positioning, followed by the need to obtain various positions of information, coordinates, speed, direction, address ....But when I get direction information, I'm stuck in a tangle ... Originally wanted to use the course value to determine the direction, but used to find, not accurate, and then think of another method, call magnetometer, with hardware to get directions, here I refer to other people's articlesReference: http://blog.csdn.net/sunnyboy9/article/details

How to deal with the color of the photo, from there, why start from here. I don't know what other people are based on, but I am based on the histogram, (I said the histogram is the picture of the compass is my own argument) Let's introduce the histogram first, and then give a few examples 1. What is a histogram? Histogram is a graphical parameter to show the accuracy of the image exposure means, which describes the image display range of images in

Tutorial description: Tool used: Corona SDK Execution difficulty: normal Operation Time: one hour Step 1: Application Overview Using the prepared image materials, we will compile our own compass Application Based on Lua and Corona SDK APIs. Basically, the final product is similar to Apple's own official compass app in iOS.Step 2: Target Development Platform First, we need to select the operating pl

The following are all converted from the android game programming entry-level classic. For more information, see the source. An interesting input method in the game is the accelerator. All Android devices require a 3D accelerator. Also, the compass function can sense the magnetic field direction and the mobile phone pitch angle. To obtain the accelerometer information, we register a listener. The interface to be implemented is sensoreventlistener, whi

Some time ago has written an article about Compass, I believe that we have a certain understanding of the compass Since the most recent project involves site search and is based on the JPA annotation form and has been on the web for a long time, there are few examples of JPA integration compass, some of which are xml-based, and very few based on annotations, The

Step 1:Create a new project Compass and import a Compass image to the res/drawable-hdpi directory. Step 2:Design the application UI, main. xml Copy codeThe Code is as follows: Android: orientation = "vertical" Android: layout_width = "fill_parent" Android: layout_height = "fill_parent" Android: gravity = "center" > Android: layout_width = "wrap_content" Android: layout_height = "wrap_content" Android: src

In this post we will show how to get the sensor informatió N of the device to do a simple compass application. Getting the magnetic orientation with the type_orientation sensor is deprecated, And now you must subscribe to type_accelerometer and type_magnetic_field to get the correct orientation. this way is a little tricky, but with this sample you will get it veryEasy. This is the code for an activity that shows in a canvas a simple

For the users of Photoshop to share a detailed tutorial on the creation of a refreshing stereo compass icon. Tutorial Sharing: First, create a new document, here I use the 800*600 pixel, draw a rounded rectangle, color #e8e8e8. Second, add a layer style for this rounded rectangle. Third, copy a rounded rectangle, change the layer's fill to 0, and add a projection style. Next, we draw the shape
