Developing STM32 in ubuntu environment

Create directory
libs directory puts stm32 firmware library, src puts user source code, inc puts user header file

# mkdir libs src inc

Copy file
Copy stm32f10x? Stdperiph? Lib? V3.5.0 to the libs directory

Create Makefile.common
Create the Makefile.common file in the home directory. This is a general Makefile file file

#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

Compile firmware library
First, compile the firmware library, compile the firmware library into a static library, and the application program can directly use the

include ../../../../../Makefile.common
