LSM9DS1 fluctuating current draw
I have a system containing a LSM9DS1 sampling AXL and Mag at 50Hz (gyro is disabled). When the LSM9DS1 is not attached (desoldered) our system (MCU only) draws about 2mA (10mV average over a 5 ohm resistor). This is constant and stable current of 2mA...
LSM9DS1 High current usage
I am using the LSM9DS1 in our application with no problems normally. The gyro, axl and mag sensor all operating as requied. All written settings e.g. +/- range are set ok, and all registers read are giving the right outputs as device is moved around ...
LIS3MDL SPI reading Sequence
Hi,I'm trying to simply read WHO_AM_I (0Fh). OUT_Z_L (2Ch) and OUT_Z_H (2Dh) registers. But output data is only FFh. Also other registers too. What is the data sequence for simple read function? My SPI bus output is MSB first and clock idles low. Fo...
I have a X-NUCLEO-IKS01A2 board connected to a stm32 nucleo and I'm trying to read the temperature from the HTS221. However, I get really wrong values. Does something need to be set in the control registers before reading? Thanks.
I am using the code provided in the TN1218 sheet, and I've attached a screenshot of my variables.
LPS35HW hanging up
We have a design with LPS35HW where the part sometimes doesn't respond on the SPI bus at startup. A power cycle clears the issue. Any ideas on what could cause this?
LSM6DSOX+IIS2MDCTR
are LSM6DSOX+IIS2MDCTR a good match for a sensorfusion setup, where we want absolute heading as quaternions?should the ISS2 be connected to the slave port of LSM6?regards,Henrik

How to reach low current consumption in LSM6DSL low-power mode with event detection
HelloRegarding the IMU LSM6DSL, I was wandering if it available to reach the low-power consumption of the accelerometer (ODR = 1.6 Hz, Idd=4.5uA) with the D6D_SRC event interrupt.My application needs to reach the lowest power consumption and detect a...
