说明

这份Makefile是由CubeMX生成的Makefile，原始版本中有些路径和目录设置并不十分合理，这里做了一些修改

源文件列表设置

原本的Makefile中的源文件列表是通过换行逐一添加的，这里简化配置的过程，用wildcard函数代替实现

C_SOURCES = 
C_SOURCES += $(wildcard *.c ./Src/*.c) 
C_SOURCES += $(wildcard *.c ./ProjectDrivers/Src/*.c) 

更换文件路径

stm32中常用的HAL库和CMSIS放在同一路径下，但是一个项目中并不需要全部的HAL库源文件，因此，因此将HAL库文件摘出至ProjectDrivers文件夹下，只编译需要的HAL库文件，同时将编译过程中产生的中间文件(.o .d .lst)搬移至其他目录，不与hex文件混合

调整make过程中的打印信息

由于Makefile的包含路径较多，将编译指令全部打出的话会影响查看编译过程中的错误信息，这里修改如下：

$(BUILD_DIR)/%.o: %.c Makefile | $(BUILD_DIR) 
    @$(CC) -c $(CFLAGS) -Wa,-a,-ad,-alms=$(BUILD_DIR)/$(notdir $(<:.c=.lst)) $< -o $@
    @echo $(notdir $(<:.c=.o))
$(BUILD_DIR)/%.o: %.s Makefile | $(BUILD_DIR)
    @$(AS) -c $(CFLAGS) $< -o $@
    @echo $(notdir $(<:.s=.o))
$(BUILD_DIR)/$(TARGET).elf: $(OBJECTS) Makefile
    @$(CC) $(OBJECTS) $(LDFLAGS) -o $@
    @echo linking...
    $(SZ) $@
    rm -fR $(BUILD_DIR)/$(OBJ_DIR)
    mkdir $(BUILD_DIR)/$(OBJ_DIR)
$(BUILD_DIR)/%.hex: $(BUILD_DIR)/%.elf | $(BUILD_DIR)
    $(HEX) $< $@
    
$(BUILD_DIR)/%.bin: $(BUILD_DIR)/%.elf | $(BUILD_DIR)
    $(BIN) $< $@    
    mv -f $(BUILD_DIR)/*.o $(BUILD_DIR)/$(OBJ_DIR)/
    mv -f $(BUILD_DIR)/*.d $(BUILD_DIR)/$(OBJ_DIR)/
    mv -f $(BUILD_DIR)/*.lst $(BUILD_DIR)/$(OBJ_DIR)/
$(BUILD_DIR):
    mkdir $@        

.s文件和.c文件生成.o文件的过程中只打印当前正在编译的文件名，链接的过程中只打印link...语句表示正在链接，不显示链接全部过程，修改后的shell的编译结果如下：

$ make
main.o
stm32f4xx_hal_msp.o
stm32f4xx_it.o
system_stm32f4xx.o
stm32f4xx_hal.o
stm32f4xx_hal_cortex.o
stm32f4xx_hal_dma.o
stm32f4xx_hal_dma_ex.o
stm32f4xx_hal_exti.o
stm32f4xx_hal_flash.o
stm32f4xx_hal_flash_ex.o
stm32f4xx_hal_flash_ramfunc.o
stm32f4xx_hal_gpio.o
stm32f4xx_hal_pwr.o
stm32f4xx_hal_pwr_ex.o
stm32f4xx_hal_rcc.o
stm32f4xx_hal_rcc_ex.o
stm32f4xx_hal_tim.o
stm32f4xx_hal_tim_ex.o
startup_stm32f407xx.o
linking...
arm-none-eabi-size Output/demo_project.elf
   text    data     bss     dec     hex filename
   4348      20    1572    5940    1734 Output/demo_project.elf
rm -fR Output/obj
mkdir Output/obj
arm-none-eabi-objcopy -O ihex Output/demo_project.elf Output/demo_project.hex
arm-none-eabi-objcopy -O binary -S Output/demo_project.elf Output/demo_project.bin
mv -f Output/*.o Output/obj/
mv -f Output/*.d Output/obj/
mv -f Output/*.lst Output/obj/

可以看出编译过程已经很简洁，同时warning和error信息可以很快定位，工程也更易于扩展。
