。。。咨询下SYSTICK配置... |
1金钱
最佳答案SysTick_CLKSource_HCLK_Div8是对HCLK的8分频,fac_us代表额具体含义是指1us的情况下,SYSTick需要计数几次,你的系统时钟72M,并且SysTick_CLKSource_HCLK_Div1 1分频,那就是说SysTick时钟为72M,延时1us需要计数72次,如果你的系统时钟72M,并且SysTick_CLKSource_HCLK_Div8 8分频,那就是说SysTick时钟为72M/8=9M,延时1us需要计数9次。

He who fights with monsters should look to it that he himself does not become a monster, when you gaze long into the abyss, the abyss also gazes into you.
过于执着就会陷入其中,迷失自己,困住自己。 |
