How to connect more LSM303AH on one SPI BUS?

We are affraid when one device has CS signal down, other devices will be set to I2C there can be conflict on the SPI BUS. Is it possible connect more devices as eclosed schematic?

Using X-CUBE-MEMS1 for lsm9ds1

Hi, I want to use -CUBE-MEMS1 for lsm9ds1. By default the applications code uses LSM303AGR . Could any one give me some hints what changes I need to do for porting ECompas application for lsm9ds1. I have already ported the driver accelerometer, gyro...

Resolved! LIS2DH false positives in detection of clicks

Hello all,I am having an issue with single-click detection. I am getting false click detections at certain threshold values. I found this out yesterday when I had an MCU register lots of clicks repeatedly, but the device was not being shaken.To test,...

(LSM6DSL) how to get total G-Force

(Because I am not good at English, I used Google Translator.)​I'm using the LSM6DSL sensor now. I think that with this sensor still, the total gravity acceleration should be 1G, or 9.8.( Total - G - Force = SQRT(x^2 + y^2 + z^2 ) ) ​However, as the s...

LIS2DH taking more than 100 uA

We are using LIS2DH in our board for production. Among 1000 boards, about 50 boards were drawing much more power because of LIS2DH (the IC is functional - we are getting the accelerometer data). Once we remove the IC from the board, current dropped f...
