STM32 LL(Low Layer) library. DS18B20 is 1-Wire digital temperature sensor from Maxim IC.

• Power Supply from 3V to 5.5V
• Celsius temperature measurement with 9 to 12-bit precision, from -55 to 125 (+/-0.5).
• Each sensor has a unique 64-Bit Serial number etched into it - allows for a huge number of sensors to be used on one data bus.
• Conversion Time: < 750ms

• Multiple sensor 1-Wire scan on single port
• Single sensor on port support
• Sensor auto address resolving
• CRC data validation

How to add CPM to the project, check the link

CPMAddPackage(
        NAME DS18B20
        GITHUB_REPOSITORY ximtech/DS18B20
        GIT_TAG origin/main)

1. Start project with STM32CubeMX:
   • GPIO configuration
2. Select: Project Manager -> Advanced Settings -> GPIO -> LL
3. Generate Code
4. Add sources to project:

include_directories(${includes} 
        ${DS18B20_DIRECTORY})   # source directories

file(GLOB_RECURSE SOURCES ${sources} 
        ${DS18B20_SOURCES})    # source files

add_executable(${PROJECT_NAME}.elf ${SOURCES} ${LINKER_SCRIPT}) # executable declaration should be before libraries

target_link_libraries(${PROJECT_NAME}.elf Vector)   # add library dependencies to project
target_link_libraries(${PROJECT_NAME}.elf CRC)

3. Then Build -> Clean -> Rebuild Project
