SevenSegment

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.

Features

• From 1 to 8 digits handling
• printf function support
• Decimal point set function

Project configuration

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

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

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

3. Then Build -> Clean -> Rebuild Project

Usage

The SevenSegment.h has default configuration defines. Override them in main.h if needed

#define SEGMENT_PERIPHERAL  LL_AHB1_GRP1_PERIPH_GPIOA
#define SEGMENT_PORT GPIOA
#define SEGMENT_A  LL_GPIO_PIN_0
#define SEGMENT_B  LL_GPIO_PIN_1
#define SEGMENT_C  LL_GPIO_PIN_2
#define SEGMENT_D  LL_GPIO_PIN_3
#define SEGMENT_E  LL_GPIO_PIN_4
#define SEGMENT_F  LL_GPIO_PIN_5
#define SEGMENT_G  LL_GPIO_PIN_6
#define SEGMENT_DP LL_GPIO_PIN_7

#define DIGIT_PERIPHERAL  LL_AHB1_GRP1_PERIPH_GPIOB
