SmartMotion® MEMS Motion Sensors

Hello every body,

Hi,

Could anybody suggest configuration for MPU9250 to achive lowest power consumption when using only pedometer.

I suppose that dmp should work to trigger steps
I don't need FIFO, I'd like steps to be accumulated in internal registers

But will it work in acceleration low-power mode(CYCLES) mode??

Thank you

Hi all,
I need help about MPU6050 INT pin.
I can not activate it. It always stays at logic 0 level. Never rises.
My config values are below.
What config is missing or wrong?
Thanks a lot in advance.

Hi,

I'm trying to configure the MPU9250 to communicate via SPI, but can't seem to find any documentation on how to get started; the datasheet/register map largely seem only to discuss i2c.

Eventually I'll be aiming to use the DMP to process the raw sensor data, and send this to the host processor via SPI. Could someone please point me in the direction of any documentation on how to configure the device to achieve this?

Thanks!

I have opened the mllite_test.c program in CCS and I am able to compile and download the hex file to my MPU-9150. Which part of the code can I alter or how can I alter the code to make the accelerometer measure up to 16g instead of 2g.

Dear developers,

We use the ICS-43432 in an embedded audio application with a Blackfin BF527 from Analog Devices. We use the I2S interface to read data from the mems. We observe unusual errors with the device.

Startup We have multiple different startup patterns in the data. The specified behavior of the microphone is that after 2000 samples the digital filter is operational and that the data is actual recorded audio data. We observe the following when we apply power and fs to the device.

I need help from a smart guy, I'm real frustrated.
Problem-I can't seem to get an MPU-6050 (DFRobot SEN0142) to talk back, or talk at all. Do I need to, somehow, initialize the 6050 first? Does the 6050 wake up at 400 kHz I2C speed?

Goal-I am just trying to read who_am_i register as a learning experience. I think I need to; S, 0x68+W,check ACK, 0x75, check ACK, S, 0x68+R, check ACK, read who_am_i, send NACK, P (per pg. 37 of PS-MPU-6000A-00).

Hi,

I designed a breakout board for the MPU6050 following the Typical Operating Circuit in the datasheet but at the end the device doesn't work. I also compared the result with the commercial one (https://www.sparkfun.com/products/11028) and the only different is the exposed pad. On the PCB, I connected the e-pad to ground. My question is: connecting the e-pad to ground could be the "fatal error"? Thanks.

Hi,
I am a end user of ICM-30630. Now , we got a problem when we developed on ICM-30630. The problem is we can communication with 30630 by I2C but can't work properly by SPI. By I2c, everything is fine, we can get data . But by SPI, we can only get ID, and then when we send command to get version , It's wrong , no correct response. So, can you just send us a project can run on spi with ICM-30630, thanks!

Hi All,

I have my mpu6050 up and running but I am struggling on some of the terminology. I have added a few questions below:

1) What do you mean by sketch, when talking about calibration?

2) MPU, I am guessing this is the mpu6050 unit?

3) DMP, im not sure on this one?
