Printf debug issue - X-CUBE-BLE1&X-CUBE-MEMS1 packages

Hi, I am following the guide "Getting started with the STMicroelectronics X-CUBE-BLE1 software package for STM32CubeMX" and recreate the example named "SensorDemo" just to know how to work with this library in CubeMX.I am using a Nucleo-L4R5ZI and th...

Are there any internal pull-ups on SPI line (as on SDO PIN) on LIS2DH?

Dear all,My name is Darko Jordanoski. I am responsible for hardware development at Kessler group.I am currently working on a project: data logger, and using LIS2DH as an accelerometer. The device is used in two modes: Normal and Sleep mode.On sleep m...

What is causing corrupted data when communicating with MPU6050 with DMA?

Hi,I am using STM32F101VD to communicate via I2C with MPU6050 IMU device. Data transfer (reading and writing) is done using DMA. Additionally I connected one of my ST32's GPIO (configured as EXTI - Rising IT) to MPU's INT pin. I am using HAL librarie...

adxl sends garbage via I2c2 to blue pill

hello, i connect a stm32f103 and adxl345 and now I see a something without utf8 - range, and those changes when i movie a sensor.whats's wrong with code?

Choice of cost-sensitive microcontroller(possibly STM8L) to control 868MHz wireless sensor module with battery power - "home safety".

Types of sensors: "water leak", "temperature / fire", "gas leak", "PIR" and "AC leakage". The sensor module will connect to the LoRa transceiver (+ MCU): ATSAMR34/R35 (Atmel).

VL53L1´S API implementation for Microchip devices: Doubts.

Hi friends,I´m trying to include a Vl53l1 in my project. I am working with a PIC32MX440 microntroller.I have filled with correct functions in the files vl53l1_platfom.h and .c to use the APIs with my hardware.The commication with the sensor is right...

In ISM330DLC, is odr equals to smaling frequency? if not how to calculate the sampling frequency to calculate the FFT

What should we consider as sampling frequency to perform vibration analysis using ISM330DLC?

Hi, we are using ST ISM330DLC for measuring vibration. Our main aim is to capture accelerometer data and perform frequency analysis by computing FFT (1K and 2K points). However, we are not able to identify the sampling frequency. What should we consi...
