lmsdso32 fifo read rounding does not operate according to the data sheet application notes as it did for us the lms6dsl. Any ideas on why not would be appreciated

to make a successful read via the spi bus of the fifo in rouding mode should return 7 bytes, the 3 tag byte plus 3 words does not return correct data or count as a successful fifo (and update the fifo size). What data is returned is rubbish data. we...

Use BDU on LSM6DS3(3) FIFO registers?

The LSM6DS3's datasheet recommends setting BDU=0 for the FIFO's status and data registers, which makes sense in my opinion.The LSM6DS33's datasheet recommends setting BDU=1 for the same register block, however. I can't find any recommendations for s...

Resolved! Is it possible to measure sound intensity level from PCM samples?

I am using two PDM microphones(mems transducer) with STM32 to measure the intensity and if the intensity of the left microphone is higher than the right one then an LED should turn on and vice versa.We measure the intensity of analog signals like whe...

Doubts about the reconfiguration procedure of the LIS2DUXS12's FSM

Hi support,I'm using the LIS2DUXS12. I make you a short recap about the use of the LIS2DUXS12 with our prototype:We use 3 FSM:FSM_1: To detect the significant motion;FSM_2: To detetct the no motion;FSM_3: To detect the situation where the acceleratio...

Incorrect LSM303AGR Accelerometer Data

I'm trying to interface with the LSM303AGR using the 3-wire SPI protocol. I'm polling the registers 0x28 - 0x2D in high-accuracy mode, and what I've noticed is that the least-significant nibble of each axis is occasionally 0x1 instead of 0x0 as expec...

Unable to communicate with LSM6DSL via SPI

I have a custom setup which contains a microcontroller (non-ST) and a LSM6DSL (actually this is mounted on a STEVAL-MKI178V2) for evaluation purposes. I tried to communicate with the LSM6DSL via SPI (4-wire, tried both 1MHz and 100kHz) using the comm...
