Resolved! Can I leave INT pins unconnected for the LSM6DSO accelerometer and gyro sensor?
Can I leave INT pins (INT1 and INT2) unconnected for the LSM6DSO accelerometer and gyro sensor?In the "internal pin status" table It says that the INT2 pin is forced to connect to ground. I use neither INT1 nor INT2 in my project.Thank you,Batuhan
Resolved! No Update form lis3mdl time to time
Hello,Our board is streaming accelerometer, gyrometer(lsm6dsox) and magnetometer(lis3mdl).It sleep and wake-up depends on accelerometer threshold.Usually data is streamed out well.But time to time, data is not updated from magetometer after wake up....
MP34DT05 Sensor PDM output issue
Hello, I am trying to interface MP34DT05 - MEMS Audio sensor in mono configuration to read audio samples from sensor. Basic working of PDM Audio sensor states that, the analog signal will be sampled at PDM CLK frequency and outputted as pulse modul...
Resolved! Eleon, help, again. Latest firmware for Sensor.box...
Hello, Eleon. My app tells be that v3.47 firmware for the sensor.box is available. The Android app tries to download and install but I never could get that to work properly. Can you post the new v3.47 firmware please.Thanks,Tony
Offset cancellation procedure with LSM303AGR.
I can't figure out the right implementation of LSM303AGR offset cancellation with single measurement mode. If I set to 1 OFF_CANC an OFF_CANC_ONE_SHOT in CFG_REG_B_M, then I have to do 2 readings and apply the Offset cancellation formula? The SET / R...
Resolved! Problems Communicating with Specific Registers in the LSM6DSO while using SPI
Hi ST Community, We have been trying to test and adapt the LSM6DSO evaluation board (STEVAL-MKI196V1) for a project but have run into difficulties communicating with it using SPI. It functions and behaves as expected when placed onto a Profi-Mems boa...
What's the default state of LIS3DSH interrupt pins, and can they be configured as high-impedance?
Hello,as the title says I'm interested in understanding more about how the INT1/INT2 pins of the LIS3DSH MEMS accelerometer work. Are they push-pull or open-drain? If it's not the default, is it possible to configure the sensor to not drive them (i.e...
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...
