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...

H3LIS331: SPI read response is always 0x00

Hello, I am attempting to communicate using SPI with an H3LIS331 accelerometer. The H3LIS331 is on a custom board that originally had a LIS3DSH on it. The LIS3DSH had been working without a problem, but we were looking to expand the acceleration scal...

LIS2DS12 sampling frequency madness

I was using an ISM303DAC as an accelerometer and everything was fine. Unfortunately, the chip was discontinued, and I had to immediately replace it with LIS2DS12 because all of the accelerometer register configurations were the same. I didn't have to...

Using IIS3DHHC as Inclinometer

Hi,I am using STM32F401VE with IIS3DHHC accelerometer sensor. I wanted to use the accelerometer as inclinometer. Apparently some documents are available with the mathematical formula to convert the accelerometer into inclinometer. However, I was wond...

we're using LSM6DSOTR and communicating that with I2C and it working as expected but sometimes we suddenly see some issues and they are unpredictably happening at any moment of time. there are mainly two issues that we have seen till now.
