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...

Lis2MDL - Magnetometer

When exposing sensor to a piece of metal, the values reported go up. After removing the metal object, the values reported go down, but not to the original set of values for some reason. We want the system to gi back to original values. How do we do t...

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...

Integrate Gravity VL53L0X to STM 32 LoRa Discovery Kit, B-L072Z-LRWAN1

I would like to integrate Gravity VL53L0X to the STM 32 LoRa Discovery Kit, B-L072Z-LRWAN1. Is it possible that I can port part of the code from X-CUBE-53L0A1 into I-CUBE-LRWAN?Or what code or setting I need to include in I-CUBE-LRWAN?Basically, I wa...
