1.在主界面选择File–>New Project 或者直接点击ACCEE TO MCU SELECTOR
2.出现芯片型号选择,搜索自己芯片的型号,双击型号,或者点击Start Project进入配置
在搜索栏的下面,提供的各 种查找方式,可以选择芯片内核,型号,等等,可以帮助你查找芯片。本实验选取的芯片型号为:STM32H750IBKx。
3.配置RCC,使用外部时钟源
4.时基源选择SysTick
5.将PA10,PB7,PB8设置为GPIO_Output
6.引脚模式配置
7.时钟源设置,选择外部高速时钟源,配置为最大主频
8.工程文件的设置, 这里就是工程的各种配置 我们只用到有限几个,其他的默认即可 IDE我们使用的是 MDK V5.27
9.点击Code Generator,进行进一步配置
