Detailed Description

ESP32 时间基准实现 / ESP32 timebase implementation.

基于 esp_timer 提供微秒和毫秒时间戳。 在支持的平台上使用 systimer HAL 快速路径。 Provides microsecond and millisecond timestamps based on esp_timer. Uses optional systimer HAL fast path when available.

构造函数 / Constructor

初始化 ESP 时间基，并在支持的芯片上启用 systimer 快速路径。 Initializes the ESP timebase and enables the systimer fast path when the target supports it.
