STM32 Low Layer(LL) library. TM1637 is a kind of LED (light-emitting diode display) drive control special circuit.

How to add CPM to the project, check the link

CPMAddPackage(
        NAME TM1637
        GITHUB_REPOSITORY ximtech/TM1637
        GIT_TAG origin/main)

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

include_directories(${includes}
        ${TM1637_DIRECTORY})   # source directories

file(GLOB_RECURSE SOURCES ${sources}
        ${TM1637_SOURCES})    # source files

3. Then Build -> Clean -> Rebuild Project

In TM1637.h default defines. Override them in main.h if needed

#define TM1637_DIGITS 4

#define TM_PERIPHERAL  LL_AHB1_GRP1_PERIPH_GPIOB
#define TM_PORT        GPIOB
#define TM_CLK_PIN     LL_GPIO_PIN_0
#define TM_DAT_PIN     LL_GPIO_PIN_1
