CPMAddPackage(
        NAME SSD1306
        GITHUB_REPOSITORY ximtech/SSD1306
        GIT_TAG origin/main)

1. Start project with STM32CubeMX:
   • I2C configuration
2. Select: Project Manager -> Advanced Settings -> I2C -> LL
3. Generate Code
4. Add sources to project:

add_subdirectory(${STM32_CORE_SOURCE_DIR}/I2C/Polling)  # add I2C dependency

include_directories(${includes}
        ${SSD1306_DIRECTORY})   # matrix display source directories

file(GLOB_RECURSE SOURCES ${sources}
        ${SSD1306_SOURCES})    # matrix display source files

3. Then Build -> Clean -> Rebuild Project

In SSD1306.h default defines. Override them in main.h if needed

// Display resolution
#define SSD1306_RESOLUTION_WIDTH 128
#define SSD1306_RESOLUTION_HEIGHT 32

#define SSD1306_I2C_TIMEOUT_MS 100
#define SD1306_DEVICE_ADDRESS 0x78 // Notice: SSD1306 128x32 can only have one I2C address

// Font define section. Uncomment/comment for font enable or disable
#define SSD1306_FONT_DEFAULT  1
