Gyroscope Sensors in different iPhone models
For our project at the THM in Germany we're developing an app which should help medical staff to detect parkinson symptoms via motion sensors in an early stage (for example by examining the rotation speed of the patients' hand etc.). Is it possible t...
H3lis331dl accelerometers type? Accelerometers or Linear Accelerometers? exclude or include Gravity?
Hi all.I'm designing with H3lis331dl.I know there are 2 type of accelerometers : "Accelerometers" or "Linear Accelerometers"Linear accelerometers, which without force gravity. Imagine, in stable, output data would be (0,0,1) (g). Accelerometers, whic...
No SPI response from ICM-20948 (IMU) on STM32
I have made a simple setup with 2 ICM-20948 IMU's and an AtSAMD21 MCU, which communicated through I2C and worked fine. Now I've chosen a more powerful MCU (STM32F410R8T6), and decided that a SPI setup would be advantageous. I have made the modificati...
Resolved! SensorTile Dev Kit (STEVAL-STLKT01V1) - Not responding after a firmware update
I just started using the SensorTile Dev Kit for one of our projects. As part of testing, I was trying to update the firmware using the ST BLE Sensor app but ran into problems. The firmware file was uploaded successfully but the board stopped respondi...
Resolved! How to interface I2S MEMS microphone with STM32F4 for KWS application
Hi,I am trying to interface an I2S MEMS microphone (SPH0645) with the STM32F446RE MCU for keyword spotting application. The mic produces PCM signal. Unfortunately, I have no idea where to start on receiving and processing the data from this MEMS mic...
VL53L1_SetThresholdConfig() API not working when setting up threshold in Vl53L1x sensor
Hi,I am working on Vl53L1x sensor for designing Obstacle Detection sensor.I want to set the distance threshold for obstacle detection in particular range only.I have set threshold after following APIs: status = VL53L1_DataInit(Dev); status = VL53L1_S...
lis3dsh Wakeup
hi stm,i have studied lis3dsh app note,i didn't understand complete configuration for wakeup state machine , like after setting the registers to the specific value , interrupt will be generated , how to make it periodic interrupt , what are all the t...
Detect whether LSM6DS3 is in low-power mode or not, and enable gyro sleep accordingly.
Hi,I have an LSM6DS3 connected to an ESP32. I can see the INT1_INACT_STATE and INT1_WU interrupts attached to INT1 coming through, and I can read WU_IA and SLEEP_STATE_IA in WAKE_UP_SRC after the interrupts.However, the SLEEP_STATE_IA interrupt comes...
Resolved! LSM6DS33 WAKE_UP_SRC register not providing correct status data.
I have Pololu breakout containing a LSM6DS33 connected to a ESP32 module via I2C. INT1 is connected to GPIO15. I am driving Activity and Wake Up to INT1. The ESP32 picks up the interrupts reliably. I would like to know whether the LSM6DS33 is active ...
