前面幾個(gè)小節(jié)已經(jīng)詳細(xì)介紹了標(biāo)準(zhǔn)外設(shè)庫的組成結(jié)構(gòu)以及部分主要文件的功能描述，那么如果在開發(fā)中使用標(biāo)準(zhǔn)外設(shè)庫需要哪些描述呢？下面就進(jìn)行簡要的介紹，這兒介紹的使用方法是與開發(fā)環(huán)境無關(guān)的，在不同的開發(fā)環(huán)境中可能在操作方式上略有不同，但是總體的流程都是一樣的，下一小節(jié)將介紹在MDK ARM開發(fā)環(huán)境下使用標(biāo)準(zhǔn)外設(shè)庫的詳細(xì)過程。

首先新建一個(gè)項(xiàng)目并設(shè)置工具鏈對(duì)應(yīng)的啟動(dòng)文件，可以使用標(biāo)準(zhǔn)外設(shè)庫中提供的模板，也可以自己根據(jù)自己的需求新建。標(biāo)準(zhǔn)外設(shè)庫中已經(jīng)提供了不同工具鏈對(duì)應(yīng)的文件，位于STM32F10x_StdPeriph_Lib_V3.4.0\Libraries\CMSIS\CM3\DeviceSupport\ST\STM32F10x\startup目錄下。

其次按照使用產(chǎn)品的具體型號(hào)選擇具體的啟動(dòng)文件，加入工程。文件主要按照使用產(chǎn)品的容量進(jìn)行區(qū)分，根據(jù)產(chǎn)品容量進(jìn)行選擇即可。每個(gè)文件的具體含義可以在"stm32f10x.h"文件中找到對(duì)應(yīng)的說明，摘錄如下：
