The output from the inertial sensor should be the angular position in quaternion. WriteRegByte MPU6050SlaveAddress, MPU6050_REG_CONFIG, & h01 ' bandwith 5Hz (delay 19msec) Fs 1Kz I2C scanner Code and Video Guide to interfacing MPU9250 Gyroscope, Magnetometer and Accelerometer with a Raspberry Pi Arduino Nano: Accelerometer Gyroscope Compass MPU9250 I2C Sensor With Visuino For capturing I used the M5Stack MPU9250 4MB which as the name suggest has a MPU-9250 9DOF sensor inside. In this illustration we will going to wire 2 or more Arduino board using i2c. For the MPU-9250 sensor, the default I2C address is {'0x68','0x0C'}. The testing unit takes the roll and pitch to maintain a X/Y platform on level. Code: Select all MPU9250 I AM 0x71 I should be 0x71 MPU9250 is online MPU9250 9-axis sensor. ax); Someone did the hard work of looking up I2C Address in and Commands in . Example: sensor = mpu9250(mypi,'I2CAddress',{'0x69','0x0C'}), where '0x69' is the I2C address of the accelerometer and gyroscope of the MPU-9250 sensor and '0x0C' is the I2C address of the magnetometer of the MPU-9250 sensor. mpu9250 i2c example
