I have a question regarding using more than 1 USART on the ATXmega128a4u.
I have a board that incorporates an ESP8266 wifi module connected to USARTC0 that is sent through a USB port using CDC.
The board has all pins broken out except for pins PC2 & PC3 which are connected to Tx and Rx of the ESP board.
I would like to know how I would go about accessing another USART to have information passed to it from the ESP8266.
I know the ATXMEGA128a4u has 5 USARTS but am not sure how I would go about setting up another USART.
Could anyone please help me with this?
The schematic for the board is in the attachment.
