Hi
I try to build a sketch to do a clock with LED rings. Here is code below that I used and after the error while compiling. Any ideas what’s wrong there ? If code is validated it should compile no ? Just for infos I have already compiled few esp sketches before so I know my ESPHome setup is good (running 1.14.3).
Thanks for your ideas
