在上面工作方式下,Linux 2.6.16 之前,内核软件定时器采用timer wheel多级时间轮的实现机制,维护操作系统的所有定时事件。timer wheel的触发是基于系统tick周期性中断。 所以说这之前,linux只能支持ms级别的时钟,随着时钟源硬件设备的精度提高和软件高精度计时的需求,有了高精度时钟的内核设计。 Linux 2.6.16 ,内核支持...
关于Linux的 High-Resolution Timer 若是禁用High-Resolution Timer,那么内核是在毫秒级别处理内部时间分片。 禁用掉High-Resolution Timer不会有问题,除非你的应用程序需要在纳秒级别处理时间分片。 如下摘自:Oracle Linux: How to Disable High-Resolution Timer (文档 ID 2207818.1) High-resolution timer is implemented...

The esp_timer example is found in the ESP-IDF extension examples under system. Through this example, we will show you how to create two different types of timers, one-shot and periodic and manage them both by using the ESP Timer APIs. So let us begin!
In this guide, we will show you how to use FreeRTOS timers and delays using ESP32 and ESP-IDF. This guide also includes a comparison of vTaskDelay() function provided by FreeRTOS with different delay values in milliseconds. The High Resolution Timer (ESP Timer) provided by FreeRTOS uses ...
