STM32单片机经典例程 此目录下包含的资料是初学者/刚接触我们开发板的朋友,需要重点阅读的.里面包含了入门教程,安装手册等资料.尤其是<<ALIENTEK 战舰STM32开发板入门教程&FAQ.pdf>>,该文档所有刚接触我们开发板的朋友,都应该认真阅读一遍(STM32 microcontroller classic routines This directory contains information is a friend of a beginner/just contact our development board, it is important to read. It contains introductory tutorial, installation manual and other information. Especially the < < ALIENTEK warships STM32 development board introductory tutorial & FAQ. PDF > >, this document all the friends just contact our development board, should read it again)

说明：  ALIENTEK STM32开发板SYSTEM文件夹，采用V3.5库的头文件，使得代码可以完美移植到库函数里面使用，不过注意，在新建工程的时候，请在：Options for Target-->C/C++ 选项卡里面 Preprocessor Symbols 栏定义你的STM32芯片容量。比如:ALIENTEK 战舰STM32开发板用户，使用的是大容量的STM32芯片，则在Define栏输入：STM32F10X_HD 对于STM32F103系列芯片，设置原则如下： 16KB≤FLASH≤32KB 选择：STM32F10X_LD 64KB≤FLASH≤128KB 选择：STM32F10X_MD 256KB≤FLASH≤512KB 选择：STM32F10X_HD(ALIENTEK STM32 development board SYSTEM folder, using V3.5 library header file, so that code can be perfectly transplanted to the library function to use, but note that in the new project, please: Options for Target - > C/C++ tab in the Preprocessor Symbols column to define your STM32 chip capacity. For example: ALIENTEK warship STM32 development board users, using a large capacity STM32 chip, in the Define column input: STM32F10X_HD For STM32F103 series chips, the setting principles are as follows: 16KB < FLASH < 32KB Selection: STM32F10X_LD 64KB < FLASH < 128KB Selection: STM32F10X_MD 256KB < FLASH < 512KB Selection: STM32F10X_HD)
