Title: RTS & CTS support for ATSAMD based boards
Post by: madhu.wesly01 on April 27, 2018, 02:18:55 pm

Hi,

1. Does ATSAMD21G support RTS and CTS  (Full UART ) ?

2. If yes, how do I add/enable these pins in a SERCOM of the microcontroller core files (probably variant.cpp)?
Any pointers with reference to Arduino Zero core would be very helpful.

1. Yes, it does.
2. It depends on whatever library you are using. Full UART is enabled when TXPO=2 and RXPO=1. And you are accordingly limited in pins selection. Read the datasheet for details.
