各位大神,小弟最近使用官方例程pcnt 编译出错,不得其解,请赐教。
环境: ESP IDE3.0.0
IDF路径和版本:D:\Espressif\frameworks\esp-idf-v5.2.2
例程路径: D:\Espressif\frameworks\esp-idf-v5.2.2\examples\peripherals\pcnt\rotary_encoder
官方代码未作改动任何,貌似在链接时报的错:

以上似乎涉及均为pcnt函数,但通过查阅代码,这些函数均有源文件实体,以及在包含的头文件有定义。
请问如何解决呢?

Re: pcnt 例程编译出错
Bug has been found since I use a target ESP32-C3, however it is not support HW PCNT.
