Resolved! I am trying to use the IIS3DWB sensor in a new project. I am unable to find the correct footprint of the sensor for PCB design. I have been unable to find a properly dimensioned drawing of the solder pads which could enable me to create my own footprint.

Assembly of the device is extremely tricky since the terminals are all hidden from view and one can never be sure of the correct alignment. Also the terminal 1 is marked only through a notch on the terminal 1 and the dot on the top surface isnt visib...

Resolved! Hello ST Experts , I am new to STM32 development environment i had a query regarding how to interface MEMS microphone ics43432 with STM32F4xx nucleo 64 board , their clocking configurations in STM32cubeMX and the usage of PDM2PCM middleware.

The 1 bit PDM data output should be converted to a 16 bit PCM data format using this and what peripherals should be used in STM32cubeMX and the obtained PCM should be converted into .wav file and display it on UART/USARTWhat is the process could anyo...

Read acceleration values at the time of interrupt generation

Hello ST Community,I am using LIS2DH12 sensor for the following purpose: Generate an interrupt when the acceleration exceeds 1.7 g in any axes and read the x, y and z-axis values after the interrupt is generated. Generate an interrupt when the accele...

Resolved! IIS2DH Anti-Aliasing Low Pass Filter by Design in comparison to IIS3DWB and what are the resonance frequencies of each axis of the IIS2DH?

Hi,so far we want to compare several MEMS accelerometers and their specifications. From ST, two sensors are on our list, the IIS3DWB and the IIS2DH.For the IIS3DWB, the data sheet offers a frequency response curve at page 19 and regarding aliasing th...
