I'm attempting to use the second UART (TX1/RX1) on the Redboard ATP with some Arduino libraries (Robertsonic's library for the WAV trigger sold by Sparkfun). I know the library is probably not compatible with the Apollo, but I was hoping to borrow the basic serial messaging code from it.

I'm getting compilation errors of:
Code: Select all
'Serial1' was not declared in this scope
Do I need to configure the UART before use and if so, how?
