Lis2de12 always returning 255 value using SPI communication
I am interfacing lis2de12 sensor with TI-CC2650 via SPI. When am trying to read the WO_AM_I register, it is returning 255 value when 0X33 is the expected value according to the datasheet. I have analyzed the protocol using analyzer and things seem to...
LSM9DS1 Same value for magnetometer axis X Y Z
Hello,I'm using a LSM9DS1 for a project, accelerometer and gyroscope works well, but the magnetometer have some problems.Every measure I get the same value for axis X-Y-Z , and it seems to change randomly, see the log :12:59:38 : ACC : x: 0.142378 y...
Problem With Mpu6050 I2C.
Hi.I am trying to communicate with MPU6050 through I2C protocol. I am using STM32f103VE.The problem I have, is that after I start condition and transmitting slave address and slave internal register address, and then starting again,this time with sla...
Resolved! LSM9DS1: Get no Interrupt without polling
Hi there,I'm tring to use the lsm9ds1 with all three sensors. Because polling is too comutational expensive I want to use interrupts. But they only work for me in combination with polling.I have defind the pins PB5-7 for the interrupts on my Nucelo-F...
LIS2DH12 support for X-CUBE-MEMS
Will support be added to X-CUBE-MEMS (1.6.2.0) for the LIS2DH12?
Resolved! IIS328DQ WHO_AM_I return not 0x32
Hi, I am using IIS328DQ with SPI communication. When I Check register WHO_AM_I, it was return 0x64. It is wrong because in datasheet it mention must be 0x32. So what is the solution?Thanks

Chip select operation on MEMS sensor ISM330DLC and others.
Hello,I'm just looking at the CS pin operation of ISM330DLC and other ST mems sensors. It seems the when (CS=1) its in I2C mode. When (CS=0) its in SPI mode.Where I'm using multiple devices on an SPI channel with a sepearate CS for each device, what ...
