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 ...

Hi everyone, I wanted to know if STEVAL-MKI184v1 is compatible with X-NUCLEO-IKS01A1?

LIS3DH Startup Sequence

Hi,This is my first question to the community so hello! :)I've recently started working with the LIS3DH accelerometer and I am experiencing some difficulty in interpreting the startup sequence for the device. Using the datasheet and AN3308 the startu...

LIS2DH not functional on cold boot on our DRA726 arm boards.

When I first boot the board the accelerometer is not recognized in IIO. After a reboot it does or if I do a rmmod and then modprobe on the kernel modules.My kernel is based on the TI 4.4 kernel from the 3.02 automotive SDK. The accelerometer kernel m...

Problem with Lsm6dsl via i2c.

Hi! I have a custom pcb with Lsm6dsl connect to mcu (nrf52832) via i2c. I can write and read regs of Lsm6dsl well (who I am also return 0x6a). But when I try to write ODR bits in CTRL1_XL (10h) reg (for example 0x10) then I can not work,because it a...

I am busy with the selftest LSM6DSL and trying to implement it, but I see your equation on page 115.... but is it not wrong? Or I do not get it offcourse.

MotionPM seems to crash after 4 iterations

Posted on February 02, 2018 at 07:06My setup is very similar to my setup in previous question: https://community.st.com/message/182613-re-motionar-initialize-function-gets-stuck?commentID=182613&et=watches.email.thread#comment-182613 SensorTile + Da...

What is the time required by the STLM20 between the application of supply voltage and valid Vout? My test results suggest 2ms but was hoping to see a published value in the datasheet.
