accelerometer g sensor

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

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

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
