Simple LSM303DLHC Library for STM32

Library for using LSM303DLHC (GY-511) sensor by STM32
Tested on LSM303DLHC connected via I2C3 to ESP32 Nucleo L432KC

Features:

• 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

Project migration from STM32CubeMX to Visual Studio Code

1. Configure the project in STM32CubeMX and generate the source code.
2. Then create a project in Visual Studio Code + PlatformIO extension:
   • Board: ST Nucleo L324 KC
   • Framework: STM32Cube
3. Copy/move the generated source files from the STM32CubeMX project to the src subdirectory of Your VS Code project.
4. 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
