Resolved! Ultra-low power IMU for step counting

I need to develop a low-power embedded device with pedometer functionality. I'm looking at the LIS3DH because of it's low power, but there's no built-in pedometer application. I've also looked at the LSM6DSL, as it has built-in pedometer support, but...

Resolved! Which INEMO has the best performance?

Hello everyone,I am looking for the best IMU to use for a robotics project and I cannot decide which iNEMO is better.If I compare ASM330LHH, ISM330DHCX, ISM330DLC, LSM6DSRX it's hard to tell which one will perform better.I am looking for the one that...

LIS3MDL always output magnetic data 0 wrongly

Hello, support team.​In my design, I use 4-wire spi to transfer data between STM32F407 and LIS3MDL.Here is my configuration to LIS3MDL.CTRL_REG2 0x40 //Full-scale selection ±12 GaussCTRL_REG1 0x02 //XY low-power mode ODR 1000HzCTRL_REG4 0x00 //Z l...

Resolved! LIS2DW12 axis orientation (sign)

Hi,I have a very simple (read: stupid) question in regards to the LIS2DW12 asix alignment (sign).I have implemented my own driver, but it is heavily based on this code: https://github.com/STMicroelectronics/STMems_Standard_C_drivers/blob/master/lis2d...

Resolved! IIS2DH Z-axis not changing - stuck in mid value

I trying to find a solution as to why the Z-axis on the accelerometer is not responding. It is "stuck" at 0x80 for both high and low value. X- and Y-axis both work as they should. I can disable the Z-axis and it goes to 0x0. I set block update, the 3...

Velocity calculation in IIS3DWB vibration sensor

I am trying to compute velocity from the acceleration values by configuring the my IIS3DWB vibration sensor at +-4g. The formula I am using to calculate the instantaneous velocity is V(t) = V0 + ʃa*dt.What I am experiencing right now is a drift in my...

Resolved! LSM6DSR ODR not accuracy

Hi.i am using LMS6DSR ,and use ODR is 208Hz,but,i found that i can't get 208 samples at 1 secend.and,i had confirmed that it only about 203 Hz from Interrupt signal.so,i want to know is that normal? i can't find information about error of ODR in d...
