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...

STEVAL-PROTEUS: Serial Monitor over Micro USB

Hi all!I've recently started working on a fault classification model utilizing the proteus1 board and the NEAI studio suite. I'd ideally like to set up a serial datalogger via the onboard micro USB to both obtain and display readings, alongside bench...

Resolved! ST notifies termination of the following product: LIS3MDLTR

We embed LIS3MDLTR on our board that we produce, because this has high sensitivity: 6842 LSB/gauss. This corresponds to 0.146 mgauss/LSB, if I convert correctly. The other products has significanltly lower sensitivity: 1.5 mgauss/LSB. What are you pr...
