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.

Is there any pad example or Eagle library for the accelerometer LIS3DHH?. I would appreciate if someone can share the layout or the library, please. Best regards.

X-CUBE-53L1A1 SimpleRangingExamples using mutex in free RTOS environement

I try to add mutex in the X-CUBE-53L1A1 SimpleRangingExamples I have defined #define VL53L1_GetI2cBus(...) CO_Mutex_get() in vl53l1_platform.c #define XNUCLEO53L1A1_GetI2cBus(...) CO_Mutex_get() inX-NUCLEO-53L1A1.cand also for PutI2cBusBut the driver...

I am about to choose the IMU (6 axis gyro + acc) for my project.

The goal is to create the precise (and as cheap as possible) inclinometer, basing on the IMUs sensors. It should measure the angle change of the rotating wheel (speed up to 250 deg/s), with accuracy of 0.01 degree. I am not rejecting the fushion of f...

LSM6DSM Interrupt Confusion

Hi Everyone, I am having issues configuring INT1. I have attached my current configuration.The init code looks like this: /* * Restore default configuration. */ lsm6dsm_reset_set(&accel_ctx, PROPERTY_ENABLE); do { lsm6d...
