Can i reduce the sensitivity ("sensitivity": 1) for a microphone (IMP23ABSU) for it not to reach the 130dbSPL? What does the "samplesPerTs": 1000" translate to? Is the sampling frequency defined with "ODR": 192000" or "ODRMeasured": 192000" ? What is...
Recommendation for Long-Range Microphone for Voice Capture (4-6)m
Hi STMicroelectronics Community,I hope this message finds you well. I am currently working on a project that requires a microphone capable of capturing voice from a distance of approximately 4 to 6 meters. Any suggestions?Thank you
Resolved! Unable to write registers for the LSM6DSOX IMU sensor
I am currently working with the LSM6DSOX IMU sensor from ST and I am unable to write to registers of the sensor.I am addressing the sensor via 4 Wire SPI.For example if I try to set the output data rate which is located in the register CTRL1_XL (0x10...
how to improve the actual ODR of LIS2DH12 ?
In my design, when setting the ODR = 100Hz or below , I can get 100hz INT signals , and received 100 sets vibration data every Second. （Using XYZ data-ready as int1）and modify the ODR setting to 200Hz , just get 200 hz INT signals ，and received 145...
Resolved! ISM330DHCX: Gyro range in driver: calculation does not make sense
Greetings, I am trying to figure out the full chain scaling values for the gyro and accelerometer of the ISM330DHCX. I am reading the datasheet as well as the AN5398. According to the datasheet the output values of accelerometer and gyro is scaled w...
[mems] speed prediction in the tunnel
Hello,I have question about gps speed prediction in the tunnel.When gps loses signal in the tunnel, we can not get any speed info from gps.In that case, can we predict speed using mems? If yes, how to solve that?Thanks in advance for your advice.Best...
Resolved! Very noisy signal from IMP34DT05 recorded with STM32-F401RE
Hello,I'm using the IMP34DT05 available with the STEVAL-MIC003V1 kit to record audio the nucleo-f401re. I'm using the PDM2PCM library to convert the PDM stream to PCM data. The audio is recorded at 8kHz.I have tried reproducing 1kHz tone on the micro...
Resolved! STEVAL-STLKT01V1 SensorTile Dev Kit Changing Accelerometer Sample Frequency
Hello,I am using the SensorTile Dev Kit for collecting accelerometer and gyroscope data. I have managed to use the SDK in python for interfacing with the sensor and plotting acc and gyro data in real-time. However, I was wondering if there was a way ...
