How to get the LSM9DS1 recommended power-up sequence?

Hi, I am reading the datasheet of LSM9DS1 and it says that there are two times (rise and wait) you should respectI was thinking in a sequencer IC but if we see the schematic of the LSM9DS1 evaluation board (STEVAL-MKI159V1) it does not use any kind o...

Problem in input capturing to measure the rpm

I want to measure the rpm of bldc motor, so by using hall sensor (H.S) output we can capture the frequency. With help of Hall sensor frequency and num of motor poles, we can able to measure the RPM. I captured the frequency successfully by using inpu...
