Redboard ATP serial ports

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:

'Serial1' was not declared in this scope

Do I need to configure the UART before use and if so, how?

Check out this pull request, which includes some sample code using TX1/RX1. It works, at least in the v1.2.0 version of the core.

Sorry I didn’t get a notification of your reply - much appreciated! I’ll check that out!
