IIS2DULPX slope filter and reference value for wake-up threshold
Hi,my company is currently evaluating usage of the IIS2DULPX accelerometer in one of the products we are developing. Our use case requires that a wake-up interrupt is generated whenever acceleration sample exceeds a set threshold value. However, we w...
LSM303AGR Magnetometer Self-Test Fails on Z-Axis
I'm using the LSM303AGR magnetometer with an STM32L4 via I2C + HAL. The built-in self-test works fine for X and Y, but Z-axis always fails — the delta (self-test vs. normal) is out of range. Set UpSTM32L4, I2C, HAL driversMagnetometer config: 50 Hz...
ISM330 SPI not working
Hi,I'm trying to get the SPI interface with the ISM330DHCX to work but it seems that the SDO pin can't reach logic high levels.The above has SCL in blue and SDO in red.CS in blue and SDO in red.SCL in blue and SDI in red.Above is my hardware setup, v...
LSM303AGR Tilt-Compensated Compass
Hello STM32 Community,I'm working with the LSM303AGR magnetometer/accelerometer sensor on an STM32L4 microcontroller. I'm trying to compute a tilt-compensated heading, based on the method described in ST's application note DT0058.However, I'm runnin...
Resolved! How to integrate driver for iis2mdc magnetometer
Hi all,I need to integrate the driver for the iis2mdc magnetometer (Github: https://github.com/STMicroelectronics/stm32-iis2mdc/tree/main) into my own project for a custom board (with STM32H7A3 and i2c3). The code from the driver requires an additio...
Resolved! Is There a Dedicated Android Library for Interfacing with STHS34PF80 Proximity Sensor?
Hi,I am currently working on a project using the STHS34PF80 proximity sensor from STMicroelectronics. The platform is running Android 14.0.0_1.0.0 (L6.1.55_2.2.0 BSP). I would like to know if there is a dedicated Android driver or SDK available to di...
Integrating MotionFX: Gives random data
We've implemented an example program based on UM2220 using an lsm6dsox IMU sensor on an STM32U575 microcontroller. We're trying to use MotionFX for orientation calculation from 6 axis measurement, configured with accelerometer and gyro. The IMU senso...
Convert I3G4250D gyro raw output to understandable values
Hello STM32 community,I'm relatively new to STM32 development and I'm currently working with the I3G4250D Gyro Sensor on the STM32F411e-Discovery board. I've been using the stm32f411e_discovery_gyroscope.c file (BSP Drivers) provided by STM32Cube to ...
