Wanted to see if anyone can explain how usermods work in the new codebase. I have been away from the code for about a year, and it seems many things have changed. I am specifically trying to get 4 line display, and rotary encoder working. I have created new overide folder, and while I get no errors, it does not give me the ability to assign pins, or show any sign of functionality at build time. What used to work, seems like it does not currently work. Perhaps you have a usermod that you use that has a good description of how to get it going, or maybe you can explain it. I have tried building wemos mini, which I was sure was working before, but now it gives error codes. I am not seeing any new explanations of how the current code works. Please help where you can. Any help would be appreciated.
Thanks, Craig
