CMake_STM32

using cmake to quickly organizing your cubemx stm32 project

features:

1. HAL/LL and some system library are built as static library so that each time you add your new files/library, you won't wait for a long time rebuilding HAL/LL lib
2. generate compile_commands.json which can easily used by visual studio code's auto-complete system. c_cpp_properties.json may be edit as below

{
    "configurations": [
        {
            "name": "ProjectName",
            "cStandard": "c11",
            "cppStandard": "c++11",
            "intelliSenseMode": "macos-gcc-arm",
            "compileCommands": "${workspaceFolder}/cmake_build/compile_commands.json"
        }
    ],
    "version": 4
}

3. beta feature: automatically code import and pack to library(speed up code rebuild when sources change)

tools

• STM32CubeMX(Generate with Makefile)
  
  and have settings as below
  
• STM32CubeProgramer(Flash tool)
• CMake
• arm-none-eabi-gcc toolchain(strongly suggest)

configure

1. drag CMakeLists.txt from this rep to the root path of your project(which is generate automatically by STM32CubeMX)
2. edit your project name with below

project(A_NAME_THAT_YOU_LIKE)

3. edit ${MCU_FLAGS} to your hardware platform. if you don't know how to write, find them in Makefile which generate by CubeMX

# cpu
CPU = -mcpu=cortex-m4

# fpu
FPU = -mfpu=fpv4-sp-d16

# float-abi
FLOAT-ABI = -mfloat-abi=hard

4. check defines and include dir recording to your Makefile
5. edit your file and lib settings
6. use it well

build and flash

mkdir cmake_build # anyname\anywhere
cmake ../   # ../ is the dir with CMakeLists.txt
make -j     # build with this arg to have max speed
make flash  # flash to your device
