TV Out Library, 644p and two Serial Ports

I am using a atmega 644p with a modded mighty 1284 core and no bootloader. I have TV out working fine with one serial port using the pollserial library that comes with the TV out library.


I would like to use both serial ports on the chip, and at first glanced, totally stumped how to do it without messing up TV output.

Any advice?


Have you just tried adding Serial1.begin(speed); into setup? Am not familiar with 'pollserial' library.

if you use normal serial with tv out it will glitch the display when a byte comes in cause of interrupts, least on a 328p, I have not tried it with the 644p but I imagine the results would be the same



Disable the serial port interrupt, poll it instead?
