在实际项目中SW协议使用使用的比较多,速度更快,占用的引脚更少,推荐配置成SW协议,即Serial Wire模式; System Wake-Up : 设置低功耗模式下的自动唤醒功能,通过引脚PA0。 Timebase Source : 一般指HAL的时基,即HAL库中的uwTick,用于实现HAL_Delay()以及作为各种timeout时钟的基准。一般情况下直接选择默认的Sys Tic...

这里要讲一下为什么要屏蔽SystemInit(),因为demo只运行虚拟串口功能,在USB未插入的情况下,是进入低功耗状态,插入时从低功耗状态退出后会调用此函数。当然我们在项目中一般不会这样,系统是否运行和插USB接口没有联系。所以我在下文中把进入低功耗代码屏蔽了,自然也就不用唤醒代码了。 图7 关于USB口使能控制引脚,需...
