MEMS (sensors)

I'm using the ST iis3dwb mems accelerometer and I'm trying to configure it to use the internal FIFO and generate the interrupt lines INT1 or INT2, but they aren't firing. What am I doing wrong?

I'm using the STM32-F446RE Nucleo board. I am using PB1 and PB2 to trigger on the iis3dwb interrupts; PB1 and PB2 are setup as GPIO_EXTI1 and GPIO_EXTI2 respectively. These interrupts work as I have a breakpoint in the interrupt handler's and can tri...

Reading stale data from LIS2DE12

We are currently implementing a LIS2DE12 accelerometer into a project, but we have issues where they sometimes get "stuck" and continue reporting back the exact same values from when it was in motion.Current implementation uses 1hz refresh-rate, usin...

Very strange power profile on LSM6DSL

Good morning.We are testing several motion sensors for a commercial medical wristband. We have selected the LSM6DSL to evaluate its suitability. However, we have detected a very strange power consumption pattern. The VCC pin consumes as expected an a...

Qvar sensing - questions

I am very interested in this Qvar sensing. What i understand is this Qvar depends on the electrode discharge and the Qvar wants to take advantage of ESD, is it correct? Also does the Electrode sensing pad size affect sensing ability?How could we prot...

How to interface STEVAL-MKI197V1 with Raspberry pi to fetch accelerometer values?

Hello,I am facing a problem while using STEVAL-MKI197V1(https://www.st.com/en/evaluation-tools/steval-mki197v1.html) with Raspberry pi 2 and try to fetch the accelerometer values.I am not able to interface this with Raspberry pi 2. I am using python ...

High power consumption of the MLC in the LSM6DSOX (~500µA)

At the stage of creating a proof concept, a LSM6DSOX sensor for a wearable device was chosen. In the datasheet, its power consumption looks fine (~15µA per MLC tree), but in practice there are problems and I want to understand what the problem is. I ...

Using LIV3F with F303RE - Configuratoin/Advise needed.

Hey :)Im trying to use LIV3F with F303RE board. I have trouble to configure the LIV3F. Can it be setup like LSM6DSO for example? Here is how I did this:Can the same method be applied to LIV3F? If so, what is ClearOREF, Receive_IT, Reset and Transmit_...

LIS2DW12 in STEVAL-Smartag1 showing only 1024mg value when it is steady, What it means?

I cannot find the MEMS configuration for STM32f412G.

I want to make a accelerometer on the Stm32f412g but I cannot find the pin configurations and MEMS schematic. Does this card have a motion or accelerometer sensor ? Could u inform me about this problem ?
