Run HS Datalog from Raspberry Pi 3B to Collect Data from STEVAL-STWINKT1B

As per the Release Notes (v2.4.0 / 5-Nov-2021) for HS DataLog CLI example, I could see executable and libs are present under directory Utilities/cli_example for Raspberry Pi 3B. I have also exported and set the shared library path using command.expor...

IIS3DWB over I2C. I know SPI is preferred but I have severe space restrictions and the extra 3 signals for SPI is a problem. So questions refer to I2C comms.

Are there any I2C communication timings available available. Trials seem to indicate device is performing clock stretching and only achieving 200kHz on returned data.FIFO usage. To reduce impact of I2C overhead, I would like use single axis mode on ...

Acquire movement data while simulataneously logging on SD card and sending via bluetooth BLE using SensorTile

Hello everyone,I'm using three Sensortiles (STEVAL-STLKT01V1, firmware FP-SNS-ALLMEMS14.2.0) to monitor a person's movements.As stated in the title, I would like to simultaneously log the data on an SD card and send them via bluetooth to a PC running...

Is there an STMicro STM32 library which uses gyroscope input for a tilt compass?

I am using STMicro's proprietary (i.e. STMicro does not publish the source code for this library) MotionMC library. This library does not result in a tilt compass as reactive as almost any other compass implemented on common off the shelf Android de...

I am seeing an undershoot voltage around 1.25v for HTS221 while data transfer going on. Can you please help me to solve this issue.

Gyro_bias is not updating

HiI am using MotionGC_manager_update(&data_in, &data_out, &bias_update); library function in my program and i can able to get the data_out output from that function but the problem is bias_update is not becoming 1 it showing always 0 even though sens...

IIS328DQTR interrupt configuration issue. Interrupt are not generated and all the axis values are reported same.

Hello ,We are trying to interface the IIS328DQTR with STM32F4 MCU. Our code configuration steps are as below.Read IIS328_WHO_AM_I (0x32) register : 0x32 is read properlyEnable block data update and set the g scale to 2. Writing 0x80 to IIS328DQ_CTRL_...
