MEMS (sensors)

I see large spikes in h3lis331dl output data that are happening at rare occasions, but frequently enough to cause problems.

We are seeing something quite odd with readings.We have the device completely static on a bench, at 1kHz, as initialised below. The readings bounce around as explained elsewhere, but occassionally we get what looks like a random sample that appears ...

4-20ma or 0-10v dc to 0-3.3 analogue ip of STM32 circuit?

I want to interfacing industrial analogue sensors with STM32F030C8T6TR so I need to convert signal in to 0-3.3v signal.4-20ma to 0-3.3v0-10v to 0-3.3v​1) For converting signal which is good way using opamp or voltage divider?​​2) It is possible using...

STM32F4 Discovery kit I2C communication with LSM303DLHC.

Hi Team, I want to learn the i2c features and functions while using STM32F4 Discovery kit based on STM32F411VE and communication with LSM303DLHC.I want to know if there is any deault register selected in LSM303DLHC when no register value is mentioned...

Linux Driver for MP23DB01HP PDM Digital Microphone

I'm looking for instructions on interfacing MP23DB01HP Microphone to Cortex-A7 on STM32MP157 through I2S bus.The application note AN5027 is a good starting point but does not mention how to integrate with Linux on Cortex-A7.I've modified the devcie t...

I did not see an 'ultrasonic' forum-related category so I am posting the question here: Is it possible to do an excitation 'sweep' such as LFM or a binary encoded pattern with the STEVAL-IME011V2 (or any other ST ultrasonic driver product)?

Housing for inclinometer using MEMS, that leads to low deviation over a temperature range from -10°C to 40°C?

(1) Are there best practice examples available?(2) Can I glue the top side of the MEMS to a steel surface? I expect lower temperature deformation than when fixed with the PCB. Or does the steel surface deform the MEMS in the mentioned temperature rag...
