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?

Why can't I send an app to my SensorTile using ST BLE Sensor and Create Apps on iOS?

For my SensorTile, when I open the ST BLE Sensor app then create/use an app in Create Apps and tap Play, I get a "Board scanning has timed out" error message. Everything under "Connect to a device" interacts happily with the SensorTile. What's the pr...
