AIS2IH Register issue

I'm working with the AIS2IH accelerometer.  I've established communication via SPI, and am able to read the WHOAMI correctly, along with requesting and receiving data as expected.  However, some of the data I'm reading doesn't make a lot of sense, so...

Resolved! IIS2DULPX one shot setup

Hello I suspect I'm about to make a dumb question but I've been strugling for the past 2 days trying to just make a simple reading of the accelerometer. Just that get those values out of X, Y and Z axis...I can get the correct responses out of the WH...

Resolved! LSM6DSV36S VDD Noise Sensitivity

Is there any noise spec on VDD of LSM6DSV36S that we need to be aware of when supplying the voltage to it? I.e. concern of specific frequency of a switching regulator, ripple spec, etc. 

Signal source for internal double-tap recognition of LIS2DW12

Hi everyone,I have set up my LIS2DW12 to recognise double taps in the Z direction, which works well with the following settings:ODR = 400 Hz (High performance mode)FS = +-2gLow Noise Mode enabledTap threshold: 0b1000 = 0.5 gLatency: 0x0F = 1200 msQui...

Resolved! FFT compare function on SensorTile.Box PRO

Good Morning,I own both a SensorTile.box and a SensorTile.Box PRO. I used the SensorTile.box to identify anomaly vibrations on a device, using the prebuilt app, with slight modifications, that performs the FFT of data coming from the accelerometer an...

LIS2DW12 BOOT Bit in CTRL2 (21h) stuck on '1'

Hi,We currently use the LIS2DW12 in our design and have encountered an issue in some units after prolonged continuous operation (approximately 5–6 days). Specifically, the accelerometer output becomes unresponsive and remains stuck at a constant valu...

LSM6DSO SPI Bug for high volume project

Using the LSM6 over SPI with the RP2040 Microcontroller for a mission-critical project (flight controller for UAVs).The SPI works well. Well in theory. In practice, 1 in every 20-100 reads returns corrupt SPI data (WHOAMI reads as 0x68/0x58). This is...
