与'preemption priority'相关的其他术语在中文中也有相应的翻译。例如,'preemption'可以翻译为“抢占”、“先占”或“优先权”;“priority”可以翻译为“优先级”、“优先权”或“优先顺序”。此外,'subpriority'(子优先级)通常翻译为“次级优先级”或“子优先级”,用于在抢占...
NVIC_IRQChannelPreemptionPriority:先占优先级 NVIC_IRQChannelSubPriority:从优先级 高先占优先级中断可以打断低先占优先级的中断,即可中断嵌套。先占优先级号码越小优先级越高 当先占优先级号码相同时,从优先级号码起作用。同先占优先级下的中断是不能进行嵌套的,只能根据从优先级的号码进行排队,从优先级号码即为排队...
即NVIC_IRQChannelPreemptionPriority可以为0或1,NVIC_IRQChannelSubPriority可以赋值为0~7 NVIC_PriorityGroup_2 代表有4个抢占优先级,4个响应优先级。即NVIC_IRQChannelPreemptionPriority可以为0~3,NVIC_IRQChannelSubPriority可以赋值为0~3 NVIC_PriorityGroup_3 代表有8个抢占优先级和2个响应优先级。即NVIC_IRQChannelPr...

What is the meaning of Preemppriority and subpriority? If the number allocated to them is higher, does it mean that they are prioritized for the service than the others which are allocated less number or it is the opposite? Do i need to categorize Priority Groups if i have several interr...

在STM32微控制器中,抢占优先级(Preemption Priority)是一个关键的中断优先级概念,它决定了中断之间的嵌套关系和响应顺序。下面将详细解释STM32中的抢占优先级概念、作用、设置方法,并给出一个示例,同时提醒用户设置时的注意事项。 1. STM32中的抢占优先级概念 抢占优先级是STM32中断优先级系统中的一个组成部分,它...
