Library for using LSM303DLHC (GY-511) sensor by STM32
Tested on LSM303DLHC connected via I2C3 to ESP32 Nucleo L432KC
- Configure linear accelerometer and magnetic field sensors
- Read data from linear accelerometer and magnetic field sensors (raw data and convertion to sensor units)
- Configure interrupts
- Motion detection by linear accelerometer
- Detection of magnetic field distortion
- Orientation: pitch, roll and yaw
- Compute incline angle

- Configure the project in STM32CubeMX and generate the source code.
- Then create a project in Visual Studio Code + PlatformIO extension:
- Board: ST Nucleo L324 KC
- Framework: STM32Cube
- In platformio.ini add:
[platformio]
src_dir = Core/
include_dir = Core/Inc
- For using on-chip floating point unit. The stm32flags.py file contains additional framework build flags. Include it in Your platformio.ini and add build flags:
extra_scripts = pre:stm32flags.py
build_flags =
-Wall
-mfpu=fpv4-sp-d16 -mfloat-abi=hard
-Wl,-u,_printf_float
- For using code of this library add to platformio.ini
lib_deps = lsm303
Directory example/ cantain subdirectories: direction, interrupt, orientation Copy main.c from this subdirectories to Your Core folder instead of the existing main.c
