SmartMotion® MEMS Motion Sensors

In my test，the MPU6500 held stationary, the temperature was gradually raised to 50 ° C, when the temperature is 40 to 43 degrees Celsius, the gyro's deviation gradually increases to a maximum of 5 degrees per second.When the temperature is between 43 and 45 degrees Celsius, the gyroscope's deviation is gradually reduced.However, the temperature rise has little effect on the accelerometer. I probably test 30, there are 15 such a phenomenon.

Hi,

I am trying to write a driver for MPU6050 on i2c for a custom university board (SJOne). I am getting correct value for Who Am I register but when I am trying to get X, Y and Z values for GYRO and ACC. it is always reading 0 from their register.

I'm writing 0x00 to 0x6B (PWR_MGMT_1), 0x1B (GYRO_CONFIG) and 0x1C (ACCEL_CONFIG) registers in initialization and then reading X,Y and Z values and WhoAmI register values. And I'm getting WhoAmI register values right but X,Y and Z values as 0.

Can anyone help what I'm doing wrong here?

Hi to all,
I taked EV_ICM-20602, can I use with little board for example Arduino or Teensy?
Are there a library for it?

Hello,

I am trying to capture raw unclaibrated data from accelerometers of iOS and Android mobile phone devices. Is that possible at all? If it is possible, how do I do that? Any pointers would also be helpful.

If the answer is available for any specific device and OS version, that would be good for a start.

Kind regards

HI all,

I'm using MPU 6050 for my project. When I try to read 14 registers from register 0x3B I'm getting 7F 02 CF E3 14 EC B4 F6... Constinuously...
I'm writing 0x80 to the register 0x6B before reading from register 0x3B for device reset.

Note: I'm using TI-RTOS in my project
Please help me in this issue.

Hi All,

I am working on the project using mpu6050. (Without "A" on the package)
On the reg map, it shows it can set to low power mode with 40hz sampling rate on accelerometer.
But when I
(i) Set CYCLE bit to 1
(ii) Set SLEEP bit to 0
(iii) Set TEMP_DIS bit to 1
(iv) Set STBY_XG, STBY_YG, STBY_ZG bits to 1
Finally, I set the LP_WAKE_CTRL to 3.
The frequency I got is 10hz.

Does anyone face the same problem?
Thanks

Hello, please give me some advise how to learn this Math and Physics. Perhaps some books which I can read. Where to being?

Thanks in advance.

Hi, I am using the ICM-20602 and have seen a couple of issues where the output wraps under high rate/acceleration. Is this a known issue and is there a workaround?

With the rate wrapping, increasing the rate range from +/-500°/s to +/-2000°/s fixed the issue (at the expense of resolution) as our application never sees rates this high.

Hi there,

In Table 17 of the ICM-20649 datasheet, it specifies 3dB BW and NBW as 12106Hz and 12316Hz when GYRO_FCHOICE is 0. But sample rate is 9000Hz. Is it an error in the datasheet that the sensor bandwidth is higher than the sample rate?
