下載stm32韌體庫

建立目錄
libs目錄放stm32韌體庫，src放使用者原始碼，inc放使用者標頭檔案

# mkdir libs src inc

複製檔案
將STM32F10x_StdPeriph_Lib_V3.5.0複製到libs目錄下

建立Makefile.common
在主目錄下建立Makefile.common檔案，這個是通用Makefile檔案

#This file is included in the general Makefile, the libs Makefile and the src Makefile  
#Different optimize settings for library and source files can be realized by using arguments  
 

#Compiler optimize settings:  
# -O0 no optimize, reduce compilation time and make debugging produce the expected results (default).  
# -O1 optimize, reduce code size and execution time, without much increase of compilation time.  
# -O2 optimize, reduce code execution time compared to ‘O1’, increase of compilation time.  
 

# -O3 optimize, turns on all optimizations, further increase of compilation time.  
# -Os optimize for size, enables all ‘-O2’ optimizations that do not typically increase code size and other code size optimizations.  
#Recommended optimize settings for release version: -O3  
#Recommended optimize settings for debug version: -O0  
 

#Valid parameters :  
# OptLIB=0 --> optimize library files using the -O0 setting  
# OptLIB=1 --> optimize library files using the -O1 setting  
# OptLIB=2 --> optimize library files using the -O2 setting  
# OptLIB=3 --> optimize library files using the -O3 setting  
# OptLIB=s --> optimize library files using the -Os setting  
# OptSRC=0 --> optimize source files using the -O0 setting  
# OptSRC=1 --> optimize source files using the -O1 setting  
# OptSRC=2 --> optimize source files using the -O2 setting  
# OptSRC=3 --> optimize source files using the -O3 setting  
# OptSRC=s --> optimize source files using the -Os setting
