Implementation of 8 _ gyroscope mpu6050 and pwm control on STM32F4-Discovery Development Board

A long time ago, He transplanted the dot doctor program from stm32f103 to STM32F4-Discovery (stm32f407), battery, gyroscope and PWM motor control programs have been tested, running for a period of time, normal. The following pictures are all connected by dubang, gyroscope, serial port, and other peripherals. In addition, there is also the nrf24l01, but the program of the nrf24l01 can read and write register

The engineer shows you how the phone's accelerometer works, with video-assisted instructions

BIN CHEN May 23, 2012, Evening 10:34 12 Some mobile phone players and enthusiasts are interested in the components of some mobile phones and even want to know how they work. Now, both mobile phones and tablets are basically built-in acceleration sensors to identify the direction of the device's rotation. Bill Hammack, an engineer from Illinois University, briefed us on how this acceleration sensor works and is not a tedious sermon, but an animated film to help explain it.Bill Hammack used Andr

Cocos2d-x accelerometer instance: moving ball, cocos2d-x AccelerationNext we will use an example to describe how to access the accelerometer through layer-based accelerometer events. As shown in this example, there is a ball in the scene. When we place the mobile device horizontally, the screen is up, and then shake the mobile device left and right to change the

Principle of MEMS accelerometer for inertial navigation

One accelerometer principleThe 1.1 accelerometer consists of a MEMS sensor and a signal processing chip.1.2 MEMS Accelerometer Working principleIt is composed of upper capacitance, medium capacitance plate (movable), lower capacitance plate, etc., when the acceleration reaches a certain value, the medium capacitance plate will move, and the distance from the uppe

Onenet Kylin seat Application development: acquisition of accelerometer ADXL345 data

Because the data acquisition station is basically installed in the field or the roof, the installation location and vibration have certain influence on the accuracy of the test data. So want to have a position state data, just found Kylin made on the ADXL345, such a digital output acceleration sensor. As shown in the red box:1 , ADXL345 OverviewADXL345 is a 3-axis, digital output accelerometer based on Imems technology from Adi. The characteristics of

"Unity practical Skills" Unity3d gyroscope controls camera move rotation

Https://docs.unity3d.com/ScriptReference/Gyroscope.htmlUnity's official documentation is clear, with only one point to note:All tutorials teach you how to useinput.gyro.attitudeBut this represents the position in space, first of all you want to do like the glory of the king to shake the camera effect, you need to record the last position, each subtraction to get the offset value.The bigger problem is that the spatial value may suddenly turn negative.So it's not really good to use.Recommended for

The deviceorientationevent is the absolute value of obtaining the direction and obtaining the device at rest;Devicemotionevent is the rate at which the device moves relative to the previous timeThe device Locator API, which allows you to collect device orientation and mobile information. In addition, the API is used only on devices that have a gyroscope capability.

Use of the Android accelerometer: shake-shake function implementation

First, the principle of introduction:The function of shaking in Android phone is already very common, recently contacted this function, the principle is very simple: using accelerometer, when shaking the phone, listen to the acceleration in all directions of change, when the acceleration value exceeds the set sensitivity, then trigger shake function.Second, the use of the class:SensormanagerSensoreventlistenerThird, the function realization:1, shake a

Acceleration Sensor Accelerometer

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 system's Sensor management service. (2) Call the getdefasensensor (int type) method of SensorManager to obtain the sensor of the specified
