Interface 4 wire spi with ILPS22QS

Hello,I am developing an application that uses 8 ILPS22QS in 3-wire mode and a microcontroller that does not support this mode natively. A shift register is used to control the CS lines and it is working as expected.I tried to go around this problem ...

LSM6DSV32X ODR Accuracy

Good Afternoon,I've been working on migrating from the LSM6DSO32 to the LSM6DSV32X and I notice that neither part specifies ODR Accuracy for normal or low power modes.  Is this information available? Thank you

Looking for Accelerometer

Hi, I am looking for an accelerometer. I wonder if there is any ST MEMS chip that meets my requirements:I don't need very high max G force: 4/8G should be enoughLow power consumptionAble to send trigger, like a GPIO rising or falling signal, when acc...

LSM6DSL big gyroscope fluctuations on acceleration

Hello, I am using a LSM6DSL sensor and when applying a 2G acceleration without rotating the board, I get very important spikes on the gyroscopes of about -90°/s to +90°/s amplitude.This is very strange. Is this a normal behaviour from this sensor ? A...

lsm9ds1-gyroscope

Hi,I have an application with LSM9DS1 sensor and I expected that when I change LSM9DS1 sensor position from horizontal to vertical value will change but changed only when sensor was moving but after that valus comes almost same for horizontal or vert...
