 Although hardware timers are not subject to the limitations mentioned, they may not be as user-friendly. For instance, application components may require timer events to be triggered at specific future times, but hardware timers typically have only one "compare" value for interrupt generation. This necessitates the creation of an additional system on top of the hardware timer to keep track of pending events and ensure that callbacks are executed when the corresponding hardware interrupts occur.

 If you run the given command and see errors such as "Failed to connect", there might be several reasons for this. One of the reasons might be issues encountered by ``esptool.py``, the utility that is called by the build system to reset the chip, interact with the ROM bootloader, and flash firmware. One simple solution to try is to manually reset as described below. If it does not help, you can find more details about possible issues in the `esptool troubleshooting <https://docs.espressif.com/projects/esptool/en/latest/esp32/troubleshooting.html>`_ page.

 硬件定时器虽不受上述限制，但使用不便。例如，应用组件可能需要在特定的未来时间触发计时器事件，但硬件定时器通常只有一个“compare（比较）”值用于中断生成。为提升使用的便利性，应在硬件定时器的基础上构建某种机制来管理待处理事件列表，确保在相应的硬件中断发生时调度回调。
