LSM303 register interface compatibility ...

I recently began working on an driver software for a magnetometer application, which is intended to support both the LSM303 (the LSM303DLHC, to be exact), and the HMC5883L from Honeywell.And I didn't fail to notice that both devices have identical I2...

Resolved! Working on ISM330dlc

I am working on ism330dlc to find gyroscope x, y, and z values. I am getting x, y, and z values. I am also getting variable x, y, and z values when the board is maintained constant. I wrote registers are 0x1204,0x1160,0x1060,0X22,0X23,0X24,0X25,0X26,...

LSM6DSO32 device id 0x00 after few hours

Hi all,We got odd issue with LSM6DSO32 IMU on our device. After like 6-10 hours of working it begins to not response correctly and it stays until completely power replug. Our code tries do reinitiate IMU when it happens, but within that "frezze" stat...

LSM6dSOX_MLC

Hi All,I am currently working on a health tracker/monitor project that utilizes the LSM6DSOX sensor, interfaced with the nRF5340 platform and running Zephyr. So far, I have successfully implemented tilt and tap detection features.As the next step in ...

Continuously varying output from MEMS Gyroscope

We are using the X-STM32MP-GNSS2 (with the STM32 discovery board DK2), which has ISM330DHCX IMU. The accelerometer readings seem fine from the IMU, but the gyroscope gives enormously high and varying readings even when we are stationary. See below th...
