LIS3MDL interrupt behaviour understanding

Hi!Reading the documentation of the LIS3MDL I cannot find an answer about the behaviour of the interrupt generator.When using the device in power down, and setting the threshold values in the registers, does the device keep sampling all the time unti...

To read two sensor values with i2c

I'm trying to get the sensor value with stm32Maybe because I connected the board to one i2c and attached two sensors, the value didn't changeMost people use cereal, but I only use C, so I have to use HALThe sensor that allows you to read only one is ...

How to write multiple sensor modules with stm32 spi

I don't know how to use several sensor modules with stm32 spiThey told me to use the code I received, but I think it's wrong because even if I connect the sensor and run the code, the same value comes outDo I have to fix all the codes below? Or do I ...

I want to use some lis2hh12 chips as an acceleration sensor array，can capacitors in the circuit be shared or individually used for each chip？How to simplify the circuit connection of acceleration sensor array?

No data from IMP34DT05

Hi,I am trying to use IMP34DT05 PDM Mic with an Audio Codec.The audio codec was previously interfaced with SPM0423HD4H-WB PDM Mic and worked as expected.When I try to use the IMP34DT05 Mic, however, I see no data transmitted on the data lines. The cl...

I2C bus "discovery" in Zephyr 3.2.0 IIS2DH driver sources, how supposed to work?

Hello, in 2021 I developed a Zephyr 2.6.0 based app which interfaces with STMicro's IIS2DH accelerometer. During development stages I was able to talk more directly to this sensor through Zephyr's I2C API, by passing the following member of a valid I...

How to interface X-Nucleo-IKS02A1 with STM32L496 Disco board using LL Libraries? Tried to interface using I2C Channel using LL Libraries , but was not able to read the registers of IKS02A1.

I have hand soldered a an ASM330LHHXTR 6DOF MEMS IMU onto a breakout board and need to verify whether the IC is working or not. Can someone please suggest how can I check if it is working perfectly. Thank you!!

6D orientation detection on LIS3DH is triggered only at 1g and -1g. The threshold registers seems to have no effect on 6D orientation detection.

Facing an issue with respect to 6D orientation detections on LIS3DH. Both, 6D position and 6D movement gets triggered only at 1G. Threshold register doesn't seem to have any influence on the 6D orientation. For, 4D the detection happens exactly at t...
