Getting Started 

int main(void)
{
     board_init(); /* should be called very first. */

     logging_init(board_get_time_since_boot_ms);
     logging_stdout_backend_init();

     const board_reboot_reason_t reboot_reason = board_get_reboot_reason();
     info("[%s] %s %s", board_get_reboot_reason_string(reboot_reason),
                     board_get_serial_number_string(),
                     board_get_version_string());

     struct gpio *led = gpio_create(PINMAP_LED);
     gpio_enable(led);

     while (1) {
             gpio_set(led, gpio_get(led) ^ 1);
             sleep_ms(500);
     }

     return 0;
}

5. Build the project 

Make and CMake supported for building projects, so use your favorite.

Make

$ make

CMake

$ cmake -G Ninja -B build
$ cmake --build build

참고

For ESP-IDF or Zephyr, you can use idf.py or west repectively.

6. Flash onto the device 

Make

$ make flash

CMake

$ cmake --build build --target flash

참고

J-Link is used as the debugger by default. To change to a different debugger or a different target device, see Flash onto the device.

Integrating into an existing project 

The library can be intergrated in your project as a git submodule, using CMake FetchContent, or downloading manually.

1. Download Library 

Option 1. git submodule

$ cd ${YOUR_PROJECT_DIR}
$ git submodule add https://github.com/libmcu/libmcu.git ${THIRD_PARTY_DIR}/libmcu

Option 2. Downloading latest release

Download from releases on Github.
And put it somewhere in your project

2. Integrating into your project 

참고

Variable names between angle brackets(e.g. <SRC_FILES>) should be modified to suit your project.

Option 1. Make

LIBMCU_ROOT ?= <THIRD_PARTY_DIR>/libmcu
# The commented lines below are optional. All modules and interfaces included
# by default if not specified.
#LIBMCU_MODULES := actor metrics
include $(LIBMCU_ROOT)/projects/modules.mk

<SRC_FILES> += $(LIBMCU_MODULES_SRCS)
<INC_PATHS> += $(LIBMCU_MODULES_INCS)

#LIBMCU_INTERFACES := gpio pwm
include $(LIBMCU_ROOT)/projects/interfaces.mk

<SRC_FILES> += $(LIBMCU_INTERFACES_SRCS)
<INC_PATHS> += $(LIBMCU_INTERFACES_INCS)

Option 2. CMake

add_subdirectory(<THIRD_PARTY_DIR>/libmcu)

or

set(LIBMCU_ROOT <THIRD_PARTY_DIR>/libmcu)
include(${LIBMCU_ROOT}/projects/modules.cmake)
include(${LIBMCU_ROOT}/projects/interfaces.cmake)

# Add ${LIBMCU_MODULES_SRCS} to your target sources
# Add ${LIBMCU_MODULES_INCS} to your target includes

Option 3. CMake FetchContent

include(FetchContent)
FetchContent_Declare(libmcu
                  GIT_REPOSITORY https://github.com/libmcu/libmcu.git
                  GIT_TAG main
)
FetchContent_MakeAvailable(libmcu)

Option 4. Other

add the sources under $LIBMCU_ROOT/modules/[common, actor, ...]/src/**/*.c to your project
add the sources under $LIBMCU_ROOT/ports/<platform specific>/<feature specific>.c to your project
add $LIBMCU_ROOT/modules/[common, actor, ...]/include to the include paths for your project
