LIS3MDL SPI BUS Problem

Posted on April 11, 2017 at 12:31Hi, I have designed a circuit which has 8 LIS3mdl sensor slot on 1 spi bus.The problem when I connect only one ls3mdl sensor (other 7 are empty) to the board it works well. but most of the when I connect another one ...

LIS2DHTR Reflow Issue

Posted on March 30, 2017 at 21:02Hello,     We are working with the LIS2DHTR and have had significant yield issues after running the board through the reflow oven.  For the next run we plan to lower the temperature.  But for now we are replacing the...

LSM6DSL Min/Max specifications for ODR (Output Data Rate)

Posted on March 21, 2017 at 15:35I'm using the LSD6DSL in an application where the sampling rate (ODR for the MEMs) is important. The ODR in the datasheet is only given as 'Typical'. Could I get a more precise specification for the ODR, e.g. min/max...

LIS3DH Interrupt INT1 Mode Not Firing

Posted on April 07, 2017 at 08:14I'm using the LIS3DH set at 1 Hz ODR.  My SPI hardware seems to be working since DATA_RDY interrupts come in fine at a steady 1 second interval and the accelerometer data looks good.  In fact I get good data at all s...

Programming (setup) of LSM6DSL IMU via 4-wire SPI

Posted on April 06, 2017 at 21:58Couple of questions regarding the LSM6DSL (iNEMO intertial module) setup via the SPI interface.1. Should it possible to program the IMU at 10 MHz SPI interface or does the programming need to be done a slower speed?2...

Resolved! LSM9DS1 input-high voltage for CS inputs?

Posted on April 05, 2017 at 00:02Although powering an LSM9DS1 with 2.8V to VDDIO and VDD, I would like to use a 1.8V-logic line for one of the chip selects for ease of retrofitting an existing design with minimum upheaval.  The line is push-pull, no...

VL53L0X X-NUCLEO-53L0A1 Cover Glass

Posted on September 02, 2016 at 18:04We are developing a product using the VL53L0X IR Time-Of-Flight sensor. The sensor must be inside a plastic case looking through a IR transmissible window material. To test such an arrangement the X-NUCLEO-53L0A1...
