SmartMotion® MEMS Motion Sensors

Hi. I'm using the ICM20689 and I'm trying to go into a low power savings mode by using the Wake on Motion interrupt on the interrupt pin. I've followed the Wake on Motion steps presented in the datasheet. My problem is that right after I enable the interrupt, the pin goes high (active), although there is no motion. I read the interrupt status register, and the value is 0xE1 (Wake on Motion interrupt + data ready). When I read the interrupt status register, the pin goes low (cleared) and then after about 50-100usec, it goes back high.

Hi I got ahold of one of your ICM-20689 EVB's and an INVARM Ver-G, installed the latest data logger program and plugged it in. It can see the board but it does not log any data, and there is no user guide that I can see so far.

Any pointers? Do you have to manually configure every register?

currently, i am working in a university project that is related to air mouse technology. now my question is this how invensens smart remote works? how it improves accuracy and stability of cursor by reducing body jitter?

MPU 9250 sensor interfaced with NRF51822 for 6 axis data.Now i am getting constant data of all 6 axis.I checked with another two MPU 9250 sensor with the same code it is working fine. What will be the reason for getting same value in that sensor??Kindly help me on this. Thanks in advance.

I have an I2C bus with 6 devices on it: four banks of EEPROM, one MPU-9250, and one Analog to Digital Comparator. My software writes values to the EEPROM and reads them back to check the validity of the EEPROM. I've noticed that when my software does _not_ power on the MPU-9250 then the I2C reads/writes fail quite regularly. But, if I explicitly power _on_ the the MPU-9250, then all is well.

The addresses for the devices are:
EEPROM = 0xA0, 0xA4, 0xA8, 0xAC
MPU-9250 = 0xD0
Analog to Digital Comparator = 0x90

Hello !
I am trying to use the auto calibration for the compass on the ICM-20948.
I saw here the two kinds of motions expected to calibrate the accelerometer and gyroscope at point 4.1 (https://invensense.tdk.com/developers/wp-content/uploads/sites/2/2015/11/eMD_Software_Guide_ICM30630.pdf)
But nothing on the compass.
Could you help me with that ?

Thanks !

Good afternoon!

I have been reviewing many setups in Arduino for the 9250. I have yet to find a guide on how to properly set up the 9250, including biasing properly to get accurate readings.

As I am new to using an accelerometer, I believe it is necessary to understand exactly how to do this. If anyone knows of a tutorial, guide, or information directly related to the concept of setting up the 9250 up, I would greatly appreciate it.

Hello everyone!
In my project I use MPU-60x0 giro and accel signals with strict synchronization with other sensors. To achieve that I am using external clock for MPU-60x0.
Now a mpu-60x0 have a NRND status and I want to substitute it by a new integrated circuit but cannot find any other ICs with external reference clock capability. And not only Invensense has no such ICs, but ST and Bosch too.
So, why Invensense remove this feature from new products? Does Invensense plan to discontinue to manufacture a MPU-60x0?
Thanks.

Hi,

I'm experimenting with a now out of date IMU3000 EVB.

Basically I've hooked it up to an Arduino Nano and reading off the data over i2c. Which is working and whlist I'm on the bottom of the learning curve I'm getting solid data.

However I'm wondering about the values of registers 0x1b and 0x1c, the temp out values MSB and LSB.
