SmartMotion® MEMS Motion Sensors

Hello,

Hi,
we are using the MPU6500 in an industrial device that gets fully molded with resin in order to prevent from humidity and to make the product shock and vibration sturdy. We figured out that after the moulding process in our production the MPU6500, both, accelerometer and gyroscope show changed values in comparison to the pre-moulded status. Obviously the MPU6500 gets affected by the moulding. Maybe the resin applies some pressure to the MPU6500 housing which leads to changed MEMS behaviour.

Is tilt compensation implemented in DMP library. I am using ICM20948 and not getting correct heading when device is tilted on y and x axis. Found that tilt compensation needs to be done. Was hoping tilt compensation is default function in sensor fusion.

Hi,
We used to use GY-521 Board(consisting of MPU 6050 acclereometer) in our product.
I understand that it gives readings in terms of LSB/g. The product requirements are a bit changed now, and we were wondering if there was some way to get the conversion into mV/g (milivolt per g) ? If not, then isn't their any estimate mV/g ?

Thanks,
P

Hello together,

has someone figured out how to enable the motion wakeup of the ICM-20649 with the driver provided by Invensense? I already got the IMU working on my embedded system to return correct accelerometer and gyro values while measurement is running, so it should be initialized correctly. Unfortunately I wasn't able to set up the motion wakeup correctly to get an interrupt on PIN1 of the ICM-20649 till now.
I already tried to make the motion wakeup working with the following functions (in different combinations) without luck:

When the ICM20789 will be added to the data logger SW?

Hi everybody,
I am using ICM20649 on SPI and MAG3110, which is connected on Auxiliary master I2C bus of ICM20649.
Communication with ICM20649 on SPI is working.
At first I can communicate with magnetometer too, for example, I can read WHO AM I register.
This problem occurs shortly after configuring:
1) communication with magnetometer is stopped (no activity more on auxiliary i2c master)

Hi,
I am using yourMPU library for developing a motion application using MPU9250 with nRF52 SDK 14.2 on my custom_board.And in inv_mpu.c file, in int mpu_init(),in setup_compass(),mpu_set_bypass(1) is being called,as shown below,
int mpu_set_bypass(unsigned char bypass_on)
{
unsigned char tmp;

Hello,

We are trying to get raw data from MPU9250, using Motion Drive 6.12, but not using the DMP.

I porting the code to a BGM11S from Silicon Labs.
I'm able to read and write from I2C interface, set registers and get data from the axes.
But the behaivor and values from the sensor are very strange.
