Incorrect LSM303AGR Accelerometer Data

I'm trying to interface with the LSM303AGR using the 3-wire SPI protocol. I'm polling the registers 0x28 - 0x2D in high-accuracy mode, and what I've noticed is that the least-significant nibble of each axis is occasionally 0x1 instead of 0x0 as expec...

Unable to communicate with LSM6DSL via SPI

I have a custom setup which contains a microcontroller (non-ST) and a LSM6DSL (actually this is mounted on a STEVAL-MKI178V2) for evaluation purposes. I tried to communicate with the LSM6DSL via SPI (4-wire, tried both 1MHz and 100kHz) using the comm...

SensorTile.box programming

I have the Nucleo-L476RG board. How I can program the Sensor Tile.box?Can I program the Sensor Tile.box with Nucleo-L476RG or only I can program it with STLinkV3? STLinkV3 is very expensive...do you know any alternative?Kind regards

Hi, I am working on ASM330LHHTR gyroscope module and I able to get the Raw value . can you please provide me guidance or calculation so that I can convert raw value in actual value. And can get slope or displacement angle from ASM330LHHTR gyroscope .

Please provide the code for calculating the slope angle using ASM330LHHTR gyroscope. My code is attached here.Note:- Switch case is used to cancel the noise.

How I do I2C Connect for the ISM330DHCX sensor

* Initialize the LSM6DSL sensor */ LSM6DSL_Init(&MotionSensor); /* Configure the LSM6DSL accelerometer (ODR, scale and interrupt) */ LSM6DSL_ACC_SetOutputDataRate(&MotionSensor, 26.0f); /* 26 Hz */ LSM6DSL_ACC_SetFullScale(&MotionSensor, 4); ...

my questions relate to lis2dw12 accelerometer I am trying to understand how the device specifications.

1. In wake-up what is the relation between the threshold (WAKE_UP_THS 34h) and the angle an axis rotates ?2. What is the angle relates to when a relative reference is used ?

Hi i need your help please How to measure RPM with hall effect secsor ? i will use this task to measure the speed of a bike
