The unstable Sampling rate for LSM6DSL

Hello all,Our company is trying to switch from BMI160 to LSM6DSL due to it low power nature.For our product, accurate time representation in the level of ms is important.However, when we were experimenting with LSM6DSL, we experienced that when we ar...

LIS2DE12 spurious interrupts

Hello.I followed AN3308 (LIS3DH witch is similar to sensor in topic) configuration of wake-up interrupt with HP filter with some modifications (CTRL_REG1=5Fh).My interrupt handler reads INT1_SRC, disables INT1 pin interrupts (CTRL_REG3 = 0) and sets ...

I'm using a VL53L0X laser distance sensor with a Pyboard 1.1, and I get always the same wrong distance value. What could the reason be?

Hi,I am using a VL53l0X sensor with a Pyboard (version 1.1), and as a value for the distance detected I get always the same (8191mm), even varying the position of the object put in front of the detector. Has anyone had the same or similar problem? An...

Why LSM303AH sensors provide different value of magnetic value

Hello,I have two LSM303AH sensors, both of them give different value of magnetic field (sqrt(x² + y² + z²) ) when they exposed on the same situation, the first one is around 100 the second one is around 200 .What is the wrong with this behavior ? one...

LSM6DSL 26hz low power mode consumes too much current.

We are using the LSM6DSL chip in SPI mode with the FIFO_CTRL5 and the CTRL1_XL registers set to 26Hz.The gyro is not used. CTRL6_C's XL_HM_MODE is set to '1' to disable high performance mode.When we are not using the LSM6DSL we set both the FIFO_CTRL...

MEMS - LSM9DS1 I2C Addressing Issue

I interfaced LSM9DS1 with TI micrcontroller TMS320F28035 with I2C protocol. The LSM9DS1 is SDO_A/G pin is pulled low, so that it can be addressed with 0x6A. But what I observe is..Whenever I power the board up, it does not respond with 0x6A and respo...
