How to configure S4S sensor synchronization in LSM6DSRX module
The iNEMO inertial module LSM6DSRX supports sensor synchronization S4S for Qualcomm. Sensor data sheet mentions following S4S registers without much detail.S4S_TPH_L (04h) Sensor synchronization time frame register - low byte (r/w)S4S_TPH_H (05h) S...
Resolved! LIS3DHTR Product Life cycle?
Hi,In the company where I work we are developing hardware and we are already evaluating the LIS3DH in order to put it in our hardware devices. However we have noticed that the LIS3DH is obsolete but there is the LIS3DHTR which is the same product but...
LIS2DH12TR- Not working on 2.9V and above voltages
Hello,I am using LIS2DH12TR through SPI but I am not able to operate it on greater than 2.8V. On greater than 2.8V I am not able to read the device ID. But according to the datasheet, it is able to operate up to 3.6 V. SO how can I use this ic greate...
Resolved! [STPM3x] Production date ?
Hi,I have a STPM33 on some of my PCB and I have issue with some of them when it gets too hot. The actual datasheet tells us that the operating temperature range is -40C to +105C but I've found an old one of October 2013, another of October 2014, anot...
Resolved! MEMS SMD device marking "SO"
Hi, can anybody tell me what partnumber this is. The chip is a LGA-14 package with the "SO" marking. It is probably an accelerometer.I aslo tried to read the 2d matrix code and it says: 781120R903QE
Selecting a motion sensor
Hi,I am looking for a motion sensor with I2C that can work in the following way:Wake up from low powerStart monitoring acceleration and rotationStop monitoring (about 500ms later)Query most significant motion while monitoringGo back to sleepBasically...
Resolved! LPS22 Device ID
HiI try to read the WHO_AM_I register using SPI but I get 0xB3 instead of 0xB1. Is this correct?Regards
LSM6DSMTR Taking more power on VDDIO Pin
I am using LSM6DSMTR with a coin cell battery. I have connected the IMU with NRF52810 using a SPI line. Attached the screenshot.When I am observing the power profiler, VDDIO is gradually taking current after the SPI communication (I have used a 100...
