MEMS (sensors)

ı am having trouble about OPR_MODE while using bno055 with stm32f4

I can't read value from bno055. I am not sure but problem can be about OPR_MODE register. In datasheet p21 Config mode's value shown as xxxx0000b and in p22 config mode shown as default mode after power on. But when I go to p50 OPR_MODE register's de...

VL53L0X long range mode

I am using VL53l0x and I want to measure distances of 2 meters but I don't find the function to configure long range mode.

Set LIS2DH12 in power down mode

Hello ST Community,My application involves nRF52 series processor which interfaces with LIS2DH12 via SPI and I am trying to reduce the power consumption as much as possible when the processor is in sleep mode. I understand that, as soon as power is a...

We are using a LIS2DH12TR. In our application if we set to 2G we get a result of 400 4G = 200 8G = 100 but 16G goes to 33 and we expected 50 Are we missing something? We get same result over 20 devices Thanks Dan

Are the LSM6DSL Accelerometer axes swappable?

We have a board with a LSM6DSL chip that can be mounted horizontally or vertically.Are the X Y and Z axes symmetrical for when reading basic Accelerometer features?

I have sensor tile box. I can able to connect it to mobile app. But i am not able to see debug window in teraterm to view the details. I have tried Dfuese utility, but it is not working for me. Basically serial port is not connecting or enabled.

Algobuilder IIR Filter a10/a20 coefficient

Hi!I am using the IIR function block in Algobuilder. In the UI I can enter the coefficients manually or use a file. The implementation uses the CMSIS functions Biquad Cascade IIR Filters Using Direct Form I Structure (void arm_biquad_cascade_df1_init...

Export raw accelerometer- and FFT-values from Unicleo

Hi!I have a Nucleo board and use the FFT example that comes with Algobuilder. It shows all the data and the results from FFT in the separate window. I would like to export all the data (accelerometer values, FFT results, peaks, etc). It works with ac...

Wrong x,y and z first sample for LIS331DLH after configuration change?

I am using a LIS331DLH accelerometer chip and I have seen that when I change its configured sometimes I get double value for x, y and z but only for the first sample. Do I need to discard the first sample after configuration change like some other ch...

LSM6DSL does not respond well anymore

I was testing the LSM6DSL, at first 10 versions of my firmware, the sensor is working fine, I was able to read and write to its register. Now it does not work, reading the WHO_I_AM register gives different value than 0x6A. I hope you can help me.
