LIS3DE substitute
Hi, what is the natural replacement for the obsolete LIS3DE?Is there a model pin to pin compatible and software compatible?Thanks.
PDM MEMS microphone using I2S interface... unexpected PDM clock rate messing up converted frequency
Hello,I have a PDM MEMS microphone that I am reading in via I2S. The following parameters are set.I2S config-----------------Master Mode ReceiverMSB First24 Bits Data on 32 Bits Frame48KHz Sample rateThe PDM 2 PCM settings are as followsPDM2PCM-----...
Resolved! L3GD20H fake IC issue
It is flight controller board for drone.In the schematic is written it is L3GD20H. Is it correct?I think it is fake chip.Also output data was not good in changing temperature environment.
How do you get an interrupt if there is no target in the measuring range? (ULD API 3.4.0, VL53L1X)
The function VL53L1X_SetDistanceThreshold has as a comment that the parameter IntOnNoTarget should no longer be used. I also found in my tests that the configuration has no effect. Can someone provide more information on this?// @param IntOnNoTarge...
Resolved! Hello all, 1)How to calculate the dB SPL for a MEMS mic captured PCM values in a log file .?? What are the in particular parameters of the mic ics43432 ? 2)How do we add the acoustic_dB library to a STM32f4xx ?
My second question continues to be the how can this PCM value be converted to .wav format?i still need a deeper understanding into this domain , anybody over here can post suggestions ,links technical articles and can share their experiences for my l...
LSM9DS1 not responding to 4-wire SPI.
Hello,I have been trying for some time to get this to work. It is my understanding from the datasheet that the default values for the IC are suitable to where the acceleration and angular rates can be measured by shifting in the appropriate register ...
LIS2DW12 Unexpected interrupt event
Hi,I am using LIS2DW12 accelerometer for tilt angle detection.I expect an interrupt event when the tilt angle is crossing the threshold and is working fine.But an interrupt event is unnecessarily occurring during physical shocks/knocks which is not e...
LIS3MDLTR and STM32L431CCT6 out of store?
Recently, it became very difficult to buy some ST chips from market. The prices of these chips had rised by several times in market. When will this situation become better?:worried_face:
