MEMS (sensors)

Looking for a detailed speck for VL53L0X, register addresses, and definitions, I see a code example but i don't want to reverse engineer it. There must be a speck available, how else can you use it on any platform. I see some specks but not able program

ThanksJohn

Can i cover Vl53L0X Time of Flight sensor with glass for protection?

Hello,I am using Vl53L0X Time of Flight sensor. The sensor is going to be used in medical field, as the sensor is an IR sensor I am facing issues in covering the surface with protective glass so as to protect the sensor from the external environment ...

VL53L1 supply voltage.

Is It safe to power VL53L1 by 3.3v for continuous operation?

Can the VL53L1X be embedded in optical grade epoxy? Will it reduce performance compared to using a cover glass?

LSM9DS1 fluctuating current draw

I have a system containing a LSM9DS1 sampling AXL and Mag at 50Hz (gyro is disabled). When the LSM9DS1 is not attached (desoldered) our system (MCU only) draws about 2mA (10mV average over a 5 ohm resistor). This is constant and stable current of 2mA...

LSM9DS1 High current usage

I am using the LSM9DS1 in our application with no problems normally. The gyro, axl and mag sensor all operating as requied. All written settings e.g. +/- range are set ok, and all registers read are giving the right outputs as device is moved around ...

LIS3MDL SPI reading Sequence

Hi,I'm trying to simply read WHO_AM_I (0Fh). OUT_Z_L (2Ch) and OUT_Z_H (2Dh) registers. But output data is only FFh. Also other registers too. What is the data sequence for simple read function? My SPI bus output is MSB first and clock idles low. Fo...

I have a X-NUCLEO-IKS01A2 board connected to a stm32 nucleo and I'm trying to read the temperature from the HTS221. However, I get really wrong values. Does something need to be set in the control registers before reading? Thanks.

I am using the code provided in the TN1218 sheet, and I've attached a screenshot of my variables.

LPS35HW hanging up

We have a design with LPS35HW where the part sometimes doesn't respond on the SPI bus at startup. A power cycle clears the issue. Any ideas on what could cause this?
