MEMS (sensors)

ultrasonic sensor interfacing with stm32f4 board along with cubemx settings?

can someone help me in this.

I am using LIS3DH for my project. Spike in X,Y or Z axis observed in idle position.

I have prepared an application in which I am reading accelerometer x,y,z axis data from its registers @every 2 sec. Now what i observed is that if I keep my board at stable position without disturbing board or any surroundings still I see some spike ...

Is there an internal pullup resistor on the LIS2DE12 SDO line?

I can't find it in the datasheet but it is behaving this way in my application.

Is there an internal pullup of SPI data out?

I have a 10k pulldown on SPI SDO. I am seeing this pin sit at 1V when the device is not driving SDO, as if there is a pullup inside the device. There is nothing mentioned in the datasheet. When the device is transmitting on SDO the signals look fine....

X-NUCLEO-53L0A1 and VL53L1X problem

Hello, I have X-NUCLEO-53L0A1 kit and now I want to work with VL53L1X sensors using this kit. As I understand, the only differences between X-NUCLEO-53L0A1 and X-NUCLEO-53L1A1 are:1. Different top sensor component2. Absence of 4 digit display on X-NU...

It appears that the LIS3MDL SDO/SA1 pin is Internally pulled up. Is this correct, if so, is it controllable (Like the LIS3DH is) and why is it not mentioned in the datasheet?

Based on some other forum posts I can see with reasonable certainty that this pin is indeed held internally high. This is not mentioned anywhere in the current data-sheet, which advises that this pin can be held high or low to set different addresses...

LPS33HW I2C mode with STEVAL-MKI109V3

Hello,I would like to ask you a question. I would like to use the LPS33HW in my application with I2C bus, before I move with the software development I would like to check if the sensor works with given ambient conditions. I thought that it will be g...

FSM#1 - Why a Finite State Machine (FSM) on a sensor device? LSM6DSO: beyond the standard 6-axis module

The LSM6DSO is the first smart sensor (accelerometer + gyro) with an embedded 16 Finite State Machine.But why is (and will be) a FSM so important? Unlike a traditional computer, FSMs hold a finite number of states or outputs in response to a particul...

LIS2DW12 Orientation (Tilt) implementation

I have followed the DT097 (design tip for 6d orientation detection). When I moved from vertical position (face up) and rotated the board around X (or Y) axis the interrupt that I got ia when it is angle-complement of what I have selected e.g. 20 de...
