MEMS (sensors)

Can someone with internal knowledge confirm that the LIS3DSH in I2C mode never drives the SCL line low and that a standard "single master push-pull SCL" can be used in combination with the bidirectional SDA line.

The LIS3DSH datasheet contains the following text (not very clear):"If a receiver can’t receive another complete byte of data until it has performed some other function, it can hold the clock line, SCL LOW, to force the transmitter into a wait state....

What does COUNTER_BDR_REG1?

Hi,I am using LSM6DSO and I am trying to implement the FIFO feature. I am reading from here (https://www.st.com/content/ccc/resource/technical/document/application_note/group0/56/95/d6/a1/34/4c/49/6d/DM00517282/files/DM00517282.pdf/jcr:content/transl...

How to reduce the zero current offset reading from one of the channel of STPM33?

Hi, I am using STPM33 for energy monitering. I have 2 STPM33 in my design and hence there are 4 current sense channels where I use shunt resistors for sensing. The problem faced by me is that the fourth channel is showing an offset of 6 mA when zero ...

X-Nucleo expansion board for LSM6DSO?

Hi, is ST planning to release new version of the X-NUCLEO-IKS01A2 sensor expansion board with the newest recently released sensors? I would like to interface LSM6DSO with NUCLEO-L4. Tks

LSM6DSO no interrupt

I have a LSM6DSO and I want to test it with the data ready interrupt, but I don't get any. I am using a logic analyzer to monitor the interrupt.The registers that I set are:0x18 with value 0x010x0B with value 0x010x10 with value 0x400x0D with value 0...

Is the acceleration and jirescope sensors integrated in the pin compatible with the same?

How to use pdm to pcm conversion library?

I am working on a project where I need to calculate the ambient noise in a given environment in decibels, for that purpose I am using st microelectronics's MP34DT01-M microphone which has an digital PDM output. From the stm application notes I got t...

IIS2DH sensing Die Location

Where in the 2x2 package is the sensing die for the 3 axis located? Is it dead center? A technical answer as accurate as possible would be best. And if there is some known manufacturing variance ​of this location. ​T​hanks

Interrupt generation for activity event

Hello,I have configured LIS2DH12 to generate interrupt on INT2 pin on activity as well as a strong impact using the register values as follows:CTRL_REG1 - 0x37CTRL_REG2 - 0x00CTRL_REG3 - 0x40CTRL_REG4 - 0x88CTRL_REG5 - 0x0ACTRL_REG6 - 0x28INT1_THS - ...
