how to access the magnetometer #8

hello kriswiner, actually i have used mpu9250 library and i have got reading of the accelerometer and gyrometer data,but when i tried to communicate with mpu9250,i could not. Means that after reading data of accel. and gyro ,i have enable the bypass_i2c.then when try to something write/read with magnetometer_address(0x0C) and send start_condition of i2c ,it could not get acknowledgement.

If you perfrom an I2C scan, which devices show on the I2C bus after enabling bypass?

PatelKishanJ commented 7 years ago

thank you. actually because of some hardware issue,it cause communication problem with the magnetometer. now,i can get all data,see below. are all right?

ax ay az (meter/second square) -0.02 -0.01 -0.32

gx gy gz (degrees/second) -0.33 29.65 -0.00

mx my mz (milliGauss) -461.03 -275.13 5563.25

temperature=23.19 degrees centigrade

The mag values seem about 10x too large, and the gyro values are very large indeed if the device is at rest.

okay.so,what should i change?.. any specific setting or anything.. and i have 1 question that how can i sure that raw data is right?..any hint?..
