Issue with DFPlayer Mini using DFPlayerMini_Fast.h on Arduino Nano Every

[Serzhs]

Hi everyone,

I'm working with an Arduino Nano Every and have properly connected all the necessary pins for my DFPlayer Mini. When I use the DFRobotDFPlayerMini.h library, everything works fine, and the player plays music as expected. However, when I switch to the DFPlayerMini_Fast.h library, nothing works anymore, and the player doesn't respond.

I’m unable to figure out the cause of this issue. Has anyone experienced something similar or have any insights on what might be causing the problem?

Any help would be greatly appreciated!
