如图所示,符合最大50MHZ要求的配置为什么会不通过呢不懂,帮顶。。。 本帖最后由 nyszx 于 2015-7-10 13:40 编辑
刚才仔细看了F411手册,似乎没问题呀 又看了STM32F4XX中文参考手册,变成了 我看手册写的:42xx的如下
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
180 MHz. The maximum allowed frequency of the high-speed APB2 domain is 90 MHz. The
maximum allowed frequency of the low-speed APB1 domain is 45 MHz
405xx和415xx如下:
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
英文手册里面有2个对于RCC的介绍章节,不同系列不一样。 安 发表于 2015-7-10 14:35
