MPU9250 9-axis sensors is obsolet

Post by stefan.erni »

Hi Ben

Unfortunately, the MCU 9250 is no longer available.

The new product( ICM-20948 ) is not compatible with powersupply 3.3 Volt !!

Is there a new Nine-Axis (Gyro + Accelerometer + Compass) MEMS MotionTracking™ Device

in your do to list for FC8?

regards
Stefan

Hi Stefan,

No sensors are currently on the to do list, However we do always want to broaden our component support.

If you see a good one that you think would be useful then let us know :D

Of course with these things you could instead just use the I2C master or SPI master components to communicate with the sensor while we develop a higher level component.

Hi Ben

What about the STM Sensors?
LSM6DSOX (6axis)
LSM9DSO(9axis)
and some more….
There is a lot of C code available…and they are on a 24pin socket .

What about the STM Sensors eval board include in FC8 as board?
For tests...

What about the STM Box include in FC8 as board?

Compact board with the following high precision sensors:
– Digital temperature sensor (STTS751)
– 6-axis inertial measurement unit (LSM6DSOX)
– 3-axis accelerometers (LIS2DW12 and LIS3DHH)
– 3-axis magnetometer (LIS2MDL)
– Altimeter / pressure sensor (LPS22HH)
– Microphone / audio sensor (MP23ABS1)
– Humidity sensor (HTS221)
• Ultra-low-power ARM Cortex-M4 microcontroller with DSP and FPU
(STM32L4R9)
• Bluetooth Smart connectivity v4.2 (SPBTLE-1S)

Hi Stefan,

Just had a quick look and don't seem to be able to buy either of those sensors locally. The LSM6DSOX is available but only from China which is slightly suspect.

Looking at the demo code and the datasheet there are an insane number of functions and registers on these devices so without one handy to test I'm not even going to bother :wink:

The first dev board looks like it should be possible, the second board has a STM32L which we don't currently support, only the F versions.

Hi Ben

For me is the STEVAL-MKI109V3 is the better solution.


I think the type from the 6axis is LSM6DSOXTR
