Cannot compile ESP32 Modbus - unconnected pin
Posted: Wed Jul 27, 2022 12:35 pm
Hi,
I had this working but now when I go to compile I get a warning that there is an unconnected pin. Originally I used the pin but changed the MAX485 to a module that did not need it so changed it to unconnected and compiled and everything worked.
I then made a modification and saved it with a new name, when I went to compile I got an error and going back to the original file does the same now.
The issue is with the DDRP pin
