IMU

What kind of board give me angle and acceleration via UASRT or USB ? May be STEVAL-MKI109V3 with ....?

Which library should I use for PDM to PCM in STM32L4?

Hello everyone, I'm trying to do the PDM-PCM transformation of MP3DT05 microphone data in a STM32L433RC nucleo board. For my understanding, the better is to use an existing library... But I don't know which one I could use, and I can't even find any...

HTS221 Temperature sensor

Hello,I have one Arduino MKR ENV board which has this sensor. The problem is that I'm reading higher temperature values than expected.The routines that I use are :For calibration: /**   * HTS221_readCalibration   *   * Reads calibration values   ...

Reading from 8 or more MEMS PDM Microphones

Any advice on which STM32 MCU you'd recommend for capturing the most amount of microphones?

Affect of acceleration on the gyro: LSM6DSL, LSM6DSO, LSM6DSR

I want to use the ST MEMs IMU in a high acceleration environment - example could be race car, drone, remote control car, etc.I'd like to know how the gyro behaves under acceleration. For example, Analog Devices calls this parameter: * Linear Accelera...

Hello, What's the difference between lsm6dsrx and lsm6dsox? which one is recommended for a new design? thank you

Sensortile decoupling capacitors

The sensortile has some decoupling capacitors which need to be connected to the VDDs on the MCU but there are two values for the capacitors 1uf and 100nf, is there a map to which pins assign to which capacitors? i have found nought on both datasheet ...

is it possible to read multiple IMUs in continuous mode (LSM6DSL)?

Hi I am trying to read multiple IMU array of 6 in FIFO continous mode using SPI. The idea is to read the data very fast till it empty and change the clock selection to the next IMU and read till it empty and so on. For one IMU, it can correctly read ...

STM32F103C8 CMSIS SPI

I'm using SMT32F103C8 and I want to comunicate with MPU9250, I do not have any other SPI devices . Only MPU9250.I set 72MHz for SMT32F103C8. here is my initialization and read/write functions.void SPI_init() { RCC->APB2ENR |= RCC_APB2ENR_AFI...

Suggested replacement for LSM303CTR?

The LSM303CTR is being discontinued. Is there a suggested replacement/substitute?
