Spare serial ports ??
Posted: Thu Feb 06, 2020 9:33 pm
I have a Pro C with a GT2560 A+.
I want to attach a second serial port to use with a Ethernet to serial gateway.
I intend to leave the USB port for software upgrades/debugging.
The Mega2560 has 4 serial ports, but some of their pins are reused for other purposes.
Dose anyone know if any of the serial port TXx/RXx pins are definitely unused ??
Thanks in advance,
Dave
