linux 搭建stm32的makefile 怎么写

一 STM 32 GCC 安装

stm32 属于arm cortex-m系列thumb指令集,所以给arm用的arm-none-eabi就可以了,首先是下载

下载地址:

https://launchpad.net/gcc-arm-embedded/+download

下载其中的gcc-arm-none-eabi-version-linux.tar.bz2

解压到你知道的目录会产生

gcc-arm-none-eabi的文件夹

把该编译器添加到你的环境中:

sudo gedit ~/.bashrc

在最后一行添加:

export PATH=$PATH:/your_stm_gcc_dir/gcc-arm-none-eabi-4_8-2013q4/bin

因为我之前有添加过树莓派的编译器了,所以实际上是这样的:

export PATH=$PATH:/your_pi_gcc_dir/tools-master/arm-bcm2708/arm-bcm2708hardfp-linux-gnueabi/bin/:/your_stm_gcc_dir/gcc-arm-none-eabi-4_8-2013q4/bin

两个编译器环境中间用冒号隔开

注销后测试:

arm-none-eabi-gcc -v

可以查看到该编译器的版本,就表示可以了.

二 工程环境的建立

新建个工程文件夹,及其目录

mkdir stm_project

cd stm_project

mkdir libs

mkdir src

mkdir inc

下载,安装官方库:

stm32的寄存器不像51 avr等单片机,那么少,自己写写库,背背寄存器就可以了,所以ST公司提供了他们官方的库,为了避免重复造轮子,就直接采用他们的库,库版本为STM32_USB-FS-Device_Lib_V4.0.0,这个库多了usb支持,下载的话到st官网搜索stm32f10x就有了.

stsw-stm32121.zip

解压,把解压好的文件夹复制到刚才新建的libs里面.

在工程根目录下新建Makefile.common文件,这个为通用makefile

# include Makefile

#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

# all -->build all

# libs -->build libs only

# src -->build src only

# clean -->clean project

# tshow -->show optimize settings

#Example:

# make OptLIB=3 OptSRC=0 all tshow

TOP=$(shell readlink -f "$(dir $(lastword $(MAKEFILE_LIST)))")

PROGRAM=main

LIBDIR=$(TOP)/libs

#Adust the following line to the library in use

stm32单片机可以用Keil5、C语言或者汇编语言等语言进行编程。

在STM32F105和STM32F107互连型系列微控制器之前，意法半导体已经推出STM32基本型系列、增强型系列、USB基本型系列、互补型系列；新系列产品沿用增强型系列的72MHz处理频率。内存包括64KB到256KB闪存和20KB到64KB嵌入式SRAM。新系列采用LQFP64、LQFP100和LFBGA100三种封装，不同的封装保持引脚排列一致性，结合STM32平台的设计理念，开发人员通过选择产品可重新优化功能、存储器、性能和引脚数量，以最小的硬件变化来满足个性化的应用需求。意法半导体(STMicroelectronics)整个集团共有员工近50000名，拥有16个先进的研发机构、39个设计和应用中心、15主要制造厂，并在36个国家设有78个销售办事处。

RTC_clearflag():清除RTC标志，(参数可以多个，用“|”相加)。

rtc_flag_sec:秒中断标志。

rtc_clearflag(rtc_flag_sec) //清除RTC中秒中断标志

RTC_GetFlagStatus(): 检查指定RTC标志是否置位

while(RTC_GetFlagStatus(RTC_FLAG_SEC) == RESET) //当RTC秒中断标志没有被置位则一直循环，也就是说等待秒针跳变（这种处理方式比较不安全，一旦RTC不正常机器就死机了）。
