LSM6DSR self test
I saw there are self test related code in the driver.What's the purpose of self test and when do we need to do self test? Thanks,
Resolved! Multiple STHS34PF80 IR sensors nearby each other.
Can several STHS34PF80 IR sensors be used simultaneously, when placed not far from each other, say on the same PCB? If STHS34PF80 infrared sensors are completely passive devices, there should not be any limitations of the distance between them, even ...
Unit of measure for the MEMS IMP23ABSU microphone
Hello, i have searched for this information, but couldnt find it anywhere. Whats the unit of the measured of the MEMS IMP23ABSU mic? I have used the STEVAL-STWINKT1B with the FP-SNS-DATALOG1 from which i created several .csv files that i now need to ...
Resolved! How to switch AMICAM1\Microphones_Streaming based on NUCLEO-STM32L476RG to 24 bit resolution?
Hello!I've working with AMICAM1 module together with STM32L476RG. By default in example 16 bit resolution is used. AD1974 that used in AMICAM1 has possibility to measure with 24 bit resolution. I tried to extend the buffers and config 24 or even 32 b...
RMS velocity calculation from accelerometer data
Hello everyone. I'm working on a vibration sensor with RMS velocity output based on measurements from an accelerometer with +-16g maximum acceleration range. There is a simple equation for calculation RMS velocity range and that is : VRMS=Apeak/2*pi*...
LIS2DH12 in molded application
Does anyone know if the LIS2DH12 is ok in a molded application? We have one where we are putting it in a device completely encased in low-pressure molded rubber. The issue we are seeing is that at power up, sometimes the sensor doesn't power up prope...
Horizontal jump measure
I am currently working with a STEVAL-MKI109v3 evaluation card and a STEVAL-MKI217v1 module. I am using UNICO-GUI to collect data from the module, and then processing the data in Python using various filters such as Madgwick, Kalman, and Mahony to enh...
Resolved! How to know chip marking in MEMS sensors?
Dear Sir or Madam,I'd like to know the part number of MEMS sensors in STmicro from the marking on the chip.How to know the marking "8209/C3H/?BW JZ" ?
Resolved! how it was used as an Accelerometer with FSM
I am using lsm6dso32x.An5629 Datasheet Section 8 FSM Configuration Example implemented only Accelerometer.I don't understand.It seems that you did not set what data(gyro or accel) you use with FSM, but I don't understand how it was used as an Acceler...
