SmartMotion® MEMS Motion Sensors

Hi, I am struggling to get the I2C communication going with the ICM-20789. The datasheet tells that you can select the address via the AD0 pin. Grounded means 0x68 and connected to VDD means 0x69. Still on page 51, chapter 10 it says that the device address is 0x63...
How to understand this?
I try to establish contact by sending a command addressing the device and the "WHOAMI"-register and then a read command but I don´t get any response.
Do I miss something, like a start-up command to activate the circuit or...

All good ideas (or working codes) are welcome!

Hi all,
I using ICM-20601 IC for GYRO & Accelerometer data.I am configuring and reading data through SPI communication in FPGA,wheh i configured SPI clk as 2.5 Mhz from device i am unable to read correct data, then i clanged the SPI clk speed to 1 Mhz.I am able to read data, but it was not according to my device configuration.I configured device to +/-32g and tested by keeping the device is in stable Z-poisson so, i am expecting output of +/-1g data, but i am getting +/-4g as output.my configured registers are
regsister-6B data 09
6A data 11

Dear Invensense team,

looking at the datasheet for the ICM20602 there is only possibility for WHO_AM_I register identification.
DS-000176-ICM-20602-v1.0.pdf
And the first register starts with address 04h.

looking at the given ICM20602_eMD_nucleo_1.7 code, I see access to more identification possibilities not mentioned in datasheet.

Hello,

I am programming a microcontroller in order to use an MPU9250 to analyze the motion of an object.
My code and the design of the electronic board seem to be correct as I have been able to read the values of the accelerometer, gyroscope and magnetometer successfully.

Hi
I have an ICM-20948 on my PCB and I am collecting raw data from the accelerometer absolutely fine over the SPI.

However when using the in built I2C master to read the magnetometer I don't get any data back.

I am configuring the I2C_MST_CTRL register with the recommended value of 7 in the clock config bits.

I am configuring the USR_CTRL register to take a value of 0x20 to enable the I2C master.

Then when I want to write using the slave 4 (I thought this would be easier to debug as it has the transaction complete flag) I follow the following sequence:

Currently I am trying to get an Invensense MPU-9250 working with Android (Codeaurora Oreo release) on a SOM using the Snapdragon (msm8996). I found and set up a driver and that looks to be working just fine (cat /sys/bus/iio/iio:device0/regdump gives non-zero values when the device is connected, otherwise all zeros)). Now the next step is getting it connected to the OS through the Android Sensors HAL. I found some code under $ANDROID_ROOT/hardware/invensense/65xx, which is pretty much the same IC without the magnetometer, so that should be fine (right?).

Hello!
Please help me to find download of the Universal Datalogger software in order to evaluate an EV_INVARM_G + MPU-9250EVB combination. It does not appear anywhere in the ‘Downloads’ section of the website.

Thanks in advance

I'd like to use the embedded motionDriver library (eMD) with an ARM A8 processor. All of the libraries listed here:
https://www.invensense.com/developers/software-downloads/
appear to be for ARM cortex M series parts. Will a library for an M series processor work with an A series ARM processor? Which library should I use?

Hi there,

Am I the only one that has tried to interface to an ICM-20789 (or any other chip to be used with the eMD) from a 64-bit host? (and failed!)

The eMD source (eMD-SmartMotion_ICM20789_20689_1.0.0) is a mess with respect to use of primitive type.
Somewhere they use "long" directly, other places they typedef "unsigned long" to their own "u32" type, and finally, other places they use the "correct" C99 types "uint32_t".

BR,
Martin
