Resolved! STEVAL NKI128V1

Hey there. I just got this 3-axis accelerometer. Can I use it with Nucleo board?Thanks!

STEAL-STWINKT1 live data reading

Hello everyone,i have STEAL-STWINKT1 board. It has some sensor on it. I want to see these data live on screen and save these values. I dont need to plot fft. How can i do that without using coding with hal libraries. Thank you

Resolved! IMP23ABSU vs MP23ABS1

Does anybody know if there is any difference between these two MEMS Microphones. The IMP23ABSU does have some Ultrasonic characteristics, but my understanding is the MEMS mics would have ultrasonic bandwidth anyway.Thanks

Resolved! STWINKT1B STREAMING USB

Hi,I bought the STEVAL-STWINKT1B hoping to be able to store and plot real-time data from my accelerometer, both in the time domain and in the frequency domain (performing FFT) for the purpose of developing my project. I bought it thinking that it wou...

Vibration sensor sleep mode

Hi,We confirmed that it is due to vibration sensor (IIS3DWBTR) only because when we removed sensor IC and tested remaining board the consumption was 7.4uA with micro controller (STM32) , memory also. But after placing vibration sensor and making it i...
