STM32 Low Layer(LL) library. A seven-segment display is a form of electronic display device for displaying decimal numerals that is an alternative to the more complex dot matrix displays.
- From 1 to 8 digits handling
- printf function support
- Decimal point set function

CPMAddPackage( NAME SevenSegment GITHUB_REPOSITORY ximtech/SevenSegment GIT_TAG origin/main)
- Start project with STM32CubeMX:
- Select: Project Manager -> Advanced Settings -> GPIO -> LL
- Generate Code
- Add sources to project:
include_directories(${includes} ${SEVEN_SEGMENT_DIRECTORY}) # source directories file(GLOB_RECURSE SOURCES ${sources} ${SEVEN_SEGMENT_SOURCES}) # source files
- Then Build -> Clean -> Rebuild Project
The SevenSegment.h has default configuration defines. Override them in main.h if needed
