That was my plan. The project has to do simple things like scan a 4x4
keyboard, light assorted LEDs and send strings over the UART at 38k4 to
control something. I'd already decided that I would run all the UART
send/receive on one core and run the control on the other core. That way
the control core remains non-blocking and the UART core can block if needed.
