Not getting gyro value accurate

LSM6DOXTR , I m reading this sensor by configuring 0x10 and 0x11 modules to 0x60 and 0x60 as show in user guide by ST but  the values I get of accelerometer are correct while gyro value jump to 0 to 255 as I am only reading MSB. LSB is changing rapid...

Resolved! I2C Bus pull-up resistor for multiple slave devices

Hello,I am using multiple different sensors which require different pull-up resistors. For I2C BUS, I have to use just one pull-up resistor value for all sensors. How can I calculate or decide the resistor value? MCU is STM32WB55.Sensors are VL53L3C...

Reboot and stuck in the LSM6DSO

I am using LSM6DSO sensor to get step and two interrupts. When the sensor runs about 15 minutes, it will stop working and have no reaction. Sometimes it will reboot and the step reset to zero. This is my code for initializing the sensor, is there som...

How is temperature (shocks) affecting H3LIS100DL?

I programmed a h3LIS100DL to an interrupt threshold of 4G. Then I breathed on the chip and got an interrupt.I expect it doesn't have a hidden Rh sensor somewhere, so it has to be related to a temperature change. Is there any documentation available o...

Using multiple HTS221 sensors

I am trying to use 2 HTS221 in the same board with I2C. I have SDA pin from both sensors wired to the same pin on my PCB. When I want to use the first HTS221, I set his CS pin to HIGH and the other HTS221 CS remains LOW. However, when I try to read f...
