gyroscope for android

Bought a mpu9250 began to toss, find a lot of information, read a lot of articles ah, mpu9250 information is not many.Use the I²c link to the SCL of the Raspberry Pi, the SDA interface VCC to the 3v pin, gnd on the Raspberry Pi gnd is ok.Start tossing:To operate the MPU must use the MPU register to implement the parameters of the set and read, take the official download to see a bit, on GitHub to find a Python code, can not run too many bugs, and then streamlined a bit.Finally can read the data,

1. Cell phone's coordinate chart The Core Motion Motion Manager lets you specify how often (in seconds) to receive updates from the accelerometer and gyroscope, and lets you specify a handler block directly (handle block), which executes the handler block whenever the update is ready. The actual acceleration is broken down into two parts in core motion: Gravity and Useracceleration. Gravity represents gravity 1g in the distribution of equipment, us

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

Before because the need to test the three-axis accelerometer ADXL362 original value, so that the original value with the appropriate filtering method, but unfortunately found that no software can be very good to display the captured data, and with the waveform display, I understand some C # knowledge, and then find the relevant information to achieve the relevant interface. I call itFirst the display controls refer to xf_z1988, address http://www.baidu.com/link?url=ySKMsPCeoQvpdNsvKat_kLtG4D_ Bj

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.
