LSM6DSL Fifo Data Set Corrupted

Hello,I am using the LSM6DSL in FIFO Continuous Mode. Fifo ODR is equal to the Accelerometer and Gyroscope ODRs (no decimation configured). Data are retrieved from fifo after the FIFO_FULL interrupt is triggered.  I have a problem that appears after ...

LIS2DW12 short second interrupt pulse during SPI readout

Dear communityI'm using the LIS2DW12 accelerometer with 800Hz ODR in continuous mode. I've set the fifo watermark threshold to 25 samples and enabled the watermark interrupt on INT1-pin. I read the data from the fifo inside an interrupt-routine on a ...

LSM6DS3 problem

Posted on July 19, 2017 at 05:24Hi, i am working with LSM6DS3 sensor, this is the first time i work with type of sensor. i am trying to read out gyro z data, but it very noise when sensor is immobile.Here is my log:-120-93-127-69-79-41-85-97-72-57-8...

Resolved! LSM6DSL does not behave as expected in FIFO continous mode

Hi Everyone,I am Using the L6MSDL chip for my application (connected to a STM32L4) in FIFO Continuous Mode and I am having some troubles understanding the FIFO pattern that we can read in FIFO_STATUS3 register. I configured the LSM6DSL The following ...

How is the INT1_THS scaled on the LIS3DH sensor?

I try to use the LIS3DH as a fall sensor in an security device for elderly people. I want to use a more elaborate detection method than just using the free fall interrupt and therefore I try to define a fall as first a free fall interrupt and then an...

Resolved! Typo in datasheet for LPS25H?

Hi.I wonder if it is possible to disable the I2c interface via CTRL REG2?in 7.7 in the datasheet it seems to be possible, but specification for bit 3 seems strange:[3] I²C enable (0: I2C enable;1: SPI disable)Is above this correct in the datasheet? i...

LIS2DE12TR: Trying to set up 4D/6D mode to trigger an interrupt

The datasheet for LIS2DE12TR is utterly confusing. It is missing any kind of flowchart for how the device operates in 4D/6D mode, or how to even set up registers correctly to enable these modes without conflict. Moreover, the registers are describ...

LIS3DE reset w/o supply reset

We're using a LIS3DE in our project wired up to the MCU as following:So we're using I2C for communication and have access to both INT pins, but not to the reset line and neither is there a mechanism to hard-reset the accelerometer.During development ...
