Problems using the VL53L0X in a 3D printed tube

I would like to use the VL53L0X in a 3D printed tube with limited space. The diameter is 6,5mm.Since the emitter and collector have a conical characteristic, there are limitations as describes in an earlier post: https://community.st.com/s/question/0...

Resolved! Temperature sensor on LIS2HH12 accelerometer

Posted on June 19, 2017 at 20:00We're using the LIS2HH12 accelerometer and there's a temperature sensor listed in the datasheet accessible via the temp_L and temp_H registers (16 bits).However the numbers I get don't make any sense.The datasheet men...

LIS2DH12TR

I'm new to Accelerometer Sensor.I have few questions o this LIS2DH12TR.There are two Interrupt pins on this LIS2DH12TR.The interrupt pins are meant for Threshold detection and sending the LIS2DH12TR to sleep/wakeup mode? Can you briefly explain the f...

Recovery of Standby Mode in LIS3DH + STM32L072

Recovery of Standby Mode in LIS3DH + STM32L072I am developing using LIS3DH + STM32L072 now.I think that I want to restore with WKUP (PA0) of STM32L072 by INT1 when it enters Standby Mode and exceeds the threshold set to LIS3DH.However, I will not ret...

Interrupt line not being cleared

I'm using an H3LIS331DL chip, and relying on the set threshold to trigger an interrupt and go read the data.Everything is working fine, except occasionally it will freeze and stop reading anything. On investigation, I found the interrupt output line ...
