I am trying to use the steval-bluecoin application that is audio loop but my application needs to print the audio data to the console every 40 seconds can some one guide me on this with some snippet

P-NUCLEO-IKA02A1 EVK

Hi Sir/Mdm,I tested the EVK with the lowest PPM in clean air was 6ppm yesterday and today I tested again in clean air was 2.4ppm and is fluctuating. When I first got this EVK, it was 0.6ppm which < 1, after testing a few rounds with CO gas, then I wo...

The attractive sensor of STEVAL-MKI173V doesn't enter the information prepared state by I2C correspondence.

Composed 0x40 to the CTRL1_A register, composed 0x8C to the CFG_REG_A_M register. I had the option to peruse the information on the accelerometer by means of I2C correspondence, however the attractive sensor can't understand it. How would I change th...

Resolved! SensorTile.Box - How can i interface the SensorTile.Box to a python script using BLE Connectivity on Windows 10

Hi! I'm struggling to get a BLE connection to my SensorTile.Box throught a Python script. I searched on internet and i found BlueST-SDK for Python. However, this is working just for Linux (as i read on Docs). I tried several time installing "Bluepy" ...

Resolved! LSM6DSRX ODR variability @ 1666, 3332 and 6667 Hz?

I would like to determine if this is stable enough to be the timebase for a servo loop and/or doing integration when dead reckoning.Would be great to get this this across PVT (process, voltage, temperature).Thank you in advance for your help!

Resolved! Only getting 0's from LSM303AGR accelerometer.

Hi, I've got a STEVAL-MKI173V1 board hooked up to my uC. I ported over the driver from:https://github.com/STMicroelectronics/STMems_Standard_C_drivers/tree/master/lsm303agr_STdC I'm able to read valid magnetometer values but almost always get 0's ...

Resolved! Two's Complement for XL values

LSM6DSO Application Note, page 67: The value is expressed as a 16-bit word in two’s complement.Question: is this a SIGNED or UNSIGNED value?

Resolved! How can I calibrate lsm6dso imu sensor ? the sensor can be positioned in any way. And in these different positions I have to calibrate the sensor when the device is turned on. my different number of sensors will use this app.

How can I determine the offset values? After determining I will use the following example.https://github.com/STMicroelectronics/STMems_Standard_C_drivers/blob/master/lsm6dso_STdC/example/lsm6dso_offset.c

IS there any roadmap from ST on a potential AI IMU beyond current machine learning IMUs? Thanks

Sine BOSCH has release their AI IMU, is there any roadmap from ST on a potential AI IMU beyond current machine learning IMUs? Thanks

Hi, I am using ST LIH3DH ( ST accelerometer) We use Ultrasonic Welding process to enclose the PCB in plastics. Can ultrasonic welding damage the LIH3DH ?? Thanks
