LPS22 sensor suddenly behaving weird

I've had this problem with an ILPS22QS and now I'm having it with an LPS22HH. It has me completely mystified. The issue is like this: The pressure sensor works as normal for a week or even multiple weeks and then all of a sudden it enters a mode wher...

pdm2pcm, pcm data noisy , pdm mic nucleo f413zh

hello tout le monde, im worknig on audio project im trying to get data from a pdm microphone as pcm 8 bit and transmit the data via uart  as binary but when i transfer the data from binary to audio via audacity i can hear just noise nothing else, als...

i am using lps22hh pressure sensor but when i try to read the data and compare with standard atmospheric pressure i am getting 910hpa,but is it i need to calibrate the sensor?

ism330dlc:ctrl1_xl(10h) value is overwritten every time when tring to read other registers

My board is having the accelerometer device ism330dlc. I am trying to write the value 0x4a to CTRL1_XL(10h).I am using the default  accelerometer driver :https://github.com/torvalds/linux/tree/master/drivers/iio/imu/st_lsm6dsxI set the sampling frequ...

bring up sensors on steval-mki128v6

Hi,When bring up sensors on steval-mki128v6,  for accelerometer and gyro,  read out who_am_i value is 0x6A, which means lsm6dsm. I can use user application to get samples. But I can't find any steval-mki128v6 document online.V5 is lsm6ds3, V7 is lsm6...

IMU sensor LSM6DSV FIFO Timestamp drift

We are observing that LSM6DSV FIFO Timestamp is drifting at a constant rate when Gyro sensor is enabled.Our ImplementationWe are using 6-axis IMU sensor LSM6DSV with st_lsm6dsvx driver from ST GitHub and integrated with OSD32MP157 SiP.We've modified ...

Calculating Analog reference voltage using vref macro

I am using stm32wl55 controller to Calculate Analog reference voltage using vref macro, which is defined as follows:#define __HAL_ADC_CALC_VREFANALOG_VOLTAGE(__VREFINT_ADC_DATA__,\                                          __ADC_RESOLUTION__) \__LL_AD...
