I am using the DFRobotDFPlayerMini-1.0.1 library by Angelo. I am trying to use the actual RX TX pins on a Uno R3, but it doesn't connect unless I type in an alternate digital pin number. This is no good for my application as I have a major pin shortage. I have tried typing in
(0,1) but that is not being accepted.
The reason for using this library is because it provides a LOOP function that works well.
- How do I use the RX TX pins with this library?
- Is there another library that has a good LOOP function in it?
