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...

Temperature sensor in LIS2DH12

We read the temperature from the sensor in LIS2DH12. We tried two devices and both read 5..6degC lower than the actual temperature. The offset seems quite consistent in the range of our interest (between 0 and 50degC). The supply voltage is 3.3V.Obvi...

Is the asm330lhhx datasheet roll and pitch mapping correct?

Im getting the roll and pitch changed. The correct direction of the roll is the x-axis and the pitch is the y-axis? 

LIS2DS12TR sleep inactivity bit doesn't change correctly

Hi,Because of internal pullups on several st accs I changed it with this acc and, now I have a problem with sleep-state or sleep-state-ia bits in wake_up_src or state or state_dup regisers. This bits after the sleep duration doesn't give a response o...
