MPU9255-Arduino-Library

[

](LICENSE)

Arduino library for MPU9255 based modules.

Read acceleration, angular velocity and magnetic field strength on your Arduino board using MPU9255 based IMU module connected via the I2C interface.

Features

• Acceleration, angular velocity, magnetic field measurements.
• Dice temperature measurements using built-in sensor.
• Selectable scale (from +- 2g , +- 250 dps to +- 16g , +-2000 dps).
• Selectable bandwidth for gyroscope and accelerometer.
• Power reduction support.
• Reset control.
• Motion interrupt support.

Compatible IDE

Library is compatible with arduino IDE 1.6 or newer.

Support/issue

• It seems to be a software issue. Please open an issue on github.
• It seems to be a hardware issue. Please ask in the official Arduino forum, where you will get a much faster answer than on github.

Installation

1. Download library (Clone or download -> download zip).
2. Launch Arduino IDE.
3. Go to : sketch -> include library and select "add .zip library" option.
4. Select location of downloaded library and click "open".

Connecting MPU9255 to arduino

MPU9255	Function
VCC	Power supply voltage
GND	Power supply ground
SDA	I2C data line
SCL	I2C clock line
INT	Interrupt digital output
FSYNC	Frame synchronisaion digital input**

** not supported by software. Connect to ground if unused.

Minimal setup:

MPU9255	Arduino
VCC	Either 3.3V or 5v dependng on the module.**
GND	GND
SDA	SDA
SCL	SCL
INT	-
FSYNC	GND

** MPU9255 requires 3.3V but some modules have 3.3V regulator built in. Please check your module documentation for more details.
