SmartMotion® MEMS Motion Sensors

Hello everyone,

I would need to know bias and noise density for the unit as part of developing an app, where can I find them?

Thanks.

HI,
As mentioned in the datasheet of MPU6050 here (http://store.invensense.com/ProductDetail/MPU6050-InvenSense-Inc/422200/)

"Click here for FREE ACCESS to InvenSense SensorFusion and calibration software for this device."

I registered my self and then when I tried to download above items, it shows me "you dont have access to do this".

So please solve my problem and let me know how can I donwload it.

Regards,

Hello,

I am using the Motion Driver 5.1.3 with the MPU-6500, thus restricting to the DMP-based routines only. The run_self_test() function converts the returned gyro bias value returned into +-1000dps, and the returned accel bias values to +-16G. Are there (potentially two) errors with this?

Hello every one,

I want to use the MPL of MD6 with Intel Edison.
However, it seems only for ARM MCUs.
Is there solution for me?

Regards,

Hi,

What are the Input Impedance of the ICS-43432 for the SCLK and WS pins ?

We need these for digital simulation.

Hello all,
We are starting to develop a small project containing and MPU-6050 and MCU in the same board.
The datasheet mentions some precautions about the MPU-6050 placement, mostly about avoiding mechanical stress.

Will the MPU-6050 be affected if we pot (epoxy) the whole board?

If we place the MPU6050 in the upperside of the board, and the MCU directly below it, in the underside of the board, would have adverse effect on the MPU?

Is there any pcb placement and routing advice not mentioned in the datasheet?

Thanks!

i translated the code to a microchip microprocessor . im calibrating the bias for the acc the giro and the mag . every initialization i get results just a little bit different. when i run it through the mahoney function i get a slow drift on the pitch and the yaw.
in order to try and compensate the drift i try to manually add/subtract small values from the calculated sensors acc and gyro. that doesnt help.
i can see that deltat in mahoney algorithm has an effect on the frequency of the drift.
has anyone encounter this phenomenon and can suggest a solution ?

Hello,
There is a bug in the mpu_read_fifo function of the Embedded Motion Driver 5.1.3:
If it's called when there is less than one complete packet in the FIFO, it returns immediately without setting the 'more' flag to 0. The mpu_read_fifo_stream function does set the more flag correctly in this case.

I've write the code as the datasheet 5.1 section: Wake-on-Motion Interrupt, but when I flip the z axis, then read out using i2c bus, the z axis sign bit is not changed.
void MPU6500_StartMotionDetection(void)
{
data = MPU6500_CONFIG_LPFILTER_184Hz;
MPU6500_WriteRegister(MPU6500_CONFIG_ADR, data);
