手册上写了:
Several prescalers are used to configure the AHB frequency, the high-speed APB (APB2)
and the low-speed APB (APB1) domains. The maximum frequency of the AHB domain is
168 MHz. The maximum allowed frequency of the high-speed APB2 domain is 84 MHz. The
maximum allowed frequency of the low-speed APB1 domain is 42 MHz

这是最大值吧,F411的时钟是100MHZ,不知道怎样分频成这个值,
好的,谢谢,不过没用过Hal库熟悉起来大概要多久?
你试试就知道,很快!几乎算是傻瓜式的。不过要是想研究底层就有点复杂了,因为架构太复杂。不过最近几次用cube作简单工作,代码工作量都大大减少了。
