User calibration for LSM6DSM IMU?

I'm designing production test for a board that integrates the LSM6DSM imu. I was wondering if it was necessary to do any calibration of the IMU during the test process or if the factory calibration is sufficient?

LSM9DS1 accelerometer and gyroscope initial transient

Hi everybody, I noticed that the accelerometric and gyroscopic signals are perturbed by an initial transient, like the one in the attached figure. What could be the issue?Thanks,Daniele

The datasheet of STEVAL-MKI227KA does not include any information about dimensions of the product. How can I find that information OR 3D model, symbol footprint document?

As a complete beginner, how do I program the Sensor Tile STEVAL-STLKT01V1.

I have purchased the STEVAL-STLKT01V1 sensor tile development kit. I have plugged the sensor tile onto the Cradle Expansion board and connected the SWD cable to a Nucleo-F070RB development board. As a complete beginner I am struggling to understand h...

PDM microphone glitch at beginning of the recording

Hello,I'm using the IMP34DT05 microphone using the I2S interface. I'm sampling at 22kHz but I have a problem when I look at the recording saved on micro SD. In the first part of the audio, I see a glitch and then an exponential decay of that spike (s...

What could cause the LPS22HH boot phase to never finish?

I am evaluating the LPS22HH for a product, but the device acts a bit unreliably. After power-on, sometimes the BOOT_ON bit in INT_SOURCE (24h) is never cleared.I wait for at least 500ms before checking the BOOT_ON bit, so that should be plenty of tim...

Question about LPS22HH: about POR

I read document AN5209. This said " VDD must be lower than 0.2 V for at least 10 ms during power-off sequence for correct POR. (3.1 Figure 2)"If POR did not finish correctly, is there the possibility to be read the un-correct data?
