Resolved! LSM6DSO Int2 on Int1although it is disabled
Hi,we are using the LSM6DSO in Fifo mode and with the double tap feature. Our firmware configures the Sensor Frontend to give an interrupt at fifo_th on INT1 and for double_tap on INT2. Therefore, we explicitly disabled the INT2_on_INT1 bit inside th...
Resolved! LPS28DFW vibration susceptibility
Hello,I am wondering if the presence of gel in the LPS28DFW makes it more susceptible to vibration than LPS22DF. These sensors will be in a vibration environment, and I'm concerned that the vibrating gel in the sensor will negatively affect the press...
LIS3DH: FIFO configuration freezes acceleration readings
Hello all,I want to use FIFO to store my acceleration data.When FIFO is not configured, the data I read from OUT_X_L, OUT_X_H, OUT_Y_L, OUT_Y_H, OUT_Z_L, OUT_Z_H are okay. By "not configured" I mean FIFO_CTRL_REG = 0x00, which is the default value th...
STHS34PF80 - cover glass
Hi,we are working on integrating this sensor to our device. We would like to make it work as human detection in front of our device. I am testing this sensor using "STEVAL-MKI231KA" board without lens connected to our development board via I2C and I ...
LIS3DH: HP Filter for Z axis not working when FIFO is configured
When I configure FIFO, for some reason Z is always around 1g even though HP filter is active.Here is my setup with FIFO:write_reg(LIS_ADD, CTRL_REG1, 0x77); // 400 Hz, enable XYZwrite_reg(LIS_ADD, CTRL_REG2, 0x3C); // HP data sent to FIFO and HP enab...
LSM6DSOTR generating random interrupt and reset microcontroler (Soldering problem... or not)
Hi,I'm developing a power meter bicycle using the LSM6DSOTR with NRF52832 microcontroler. In my project I defined that 3 minutes without moviment, the system is turned off and wake up when the LSM6DSOTR detect the movement. Below, the code to init my...
STWIN Trigger reset button via USB or Firmware
Hi!I have a STEVAL-STWINKT1B sensor running the HSDatalog firmware. I am interfacing with it using an USB cable via linux and a modified version of the "cli_example" relying on the "HSDatalog.h" interface, which I am compiling using cmake. When runni...
ISM330DHCX accelerometer resister calulation
In our project we are using ism330dhcx, we are only using accelerometer, i want know how to process x,y and z axis data to get resultant.
Resolved! LSP22HB having trouble with ONE-SHOT mode
I am using the LSP22HB on an I2C bus. I can read the "who am i" register and get the expected value. I can also read various configuration registers and see the default values. So, I believe I am communicating with the device.I don't set any register...
