Sensortile.box keeps dying, and data is truncated

Hey,we have a bunch of sensor tile.box boards, but they keep dying and needs to be refreshed with the OTA. - even with the newest FWis usually happens when we try to "play" a new app (made in expert view of the ST app)When is works, the data gets tru...

Resolved! I'm using a LIS2DE12 for sensing the opening and closing of doors. 1) The chip is resetting randomly when I communicate with over I2C. 2) I need to trigger an interupt a deceleration (negative acceleration), but can't put in a negative thredshold.

The chip is powered by an 3v3 LDO. I have measured the output, and there are no fall-outs. I suspect my I2C adapter to be doing it. On-board the I2C is pulled up to 3v3 by 2k2 resistors. But on the adapter the I2C gets pulled up to 5V also by 2k2 res...

How to stream FIFO data?

I'm using the STEVAL-MKI109v3 demo board with the STEVAL-MKI193 IMU. I'd like to evaluate use of the FIFO. I've written a custom PC application based on the Unico Lite demo application. I can read from the FIFO registers properly, but it is really...

libiio and st_imu68 software hrtimer?

I compiled the st_imu68_i2c driver for use with a 4.14 linux kernel with the industrial IO subsystem successfully. And I could read values from the device using the files that provide the "raw" values. However, it is very slow when I just cat the raw...

ISM330DHCX: Hi, is there any known issue regarding the WHO_AM_I of ISM330DHCX, when having a number of them on one bus? Sometimes I read 0x48 instead of the expected 0x6B. There is no issue with SPI speed (10 MHz or 1 MHz tested).

I'm testing a system with a number of ISM330DHCX, generating the CE signals apart from the SPI component. Having a number of sensors on the bus (by means of CE only one of them active at any given time) I read sometimes a wrong WHO_AM_I-value. Bus cl...

I guys, I was looking at the VL53L1X to detec water level in a manhole but it says the field of view is 15°-27°. Being in a manhole, this is way to wide. Any suggestions?

The device I am developping on is on top of the manhole at 3-4 meters high and I need a 2-5 mm precision or so. I look forward for an idea. Looking at basic laser meters to take measurements, they all are capable of doing what I am looking for, but c...
