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?

Could not read and write the ISM330DLC each 10ms period

Dear ST Hello,I am trying to use the ISM330DLC 3D accelerometer and gyroscope with the stm32F329Discovery board and I am facing some problems when I want to read and write all the registers every 10 ms ISR period.I want to try to change the registers...
