Re: MCPWM
BTW, I only tested the code on the master branch. The code doesn't need to alter any default configuration from menuconfig.

Re: 串口初始化时,设置了多个时钟源,选择这些时钟源根本性的作用是什么?
不同的时钟源,精度和稳定性不同,功耗也不同,比如想要工作在light sleep场景下,就得选择一个在light sleep下不会被关闭的时钟源。

Re: ESP32-S3 GPIO翻转速度怎么这么慢呢?
另外,真不建议使用gpio去模拟任何协议,尤其是在一个RTOS环境下。你可以看看能否用RMT硬件构造出你要的时序:https://docs.espressif.com/projects/esp ... s/rmt.html
