这些事件很多时候是通过硬件中断产生,怎么处理中断呢? 假设当前系统正在运行Task1时,用户按下了按键,触发了按键中断。这个中断的处理流程如下: CPU跳到固定地址去执行代码,这个固定地址通常被称为中断向量,这个跳转时硬件实现的 执行代码做什么? 保存现场:Task1被打断,需要先保存Task1的运行环境,比如各类寄存器的值 分...
在任务函数中,我们可以调用各类API函数,比如队列操作函数:xQueueSendToBack。但是在ISR中使用这个函数会导致问题,应该使用另一个函数:xQueueSendToBackFromISR,它的函数名含有后缀"FromISR",表示"从ISR中给队列发送数据"。 FreeRTOS中很多API函数都有两套:一套在任务中使用,另一套在ISR中使用。后者的函数名含有"FromISR...
