For Arduino Leonardo (ATmega32U4),
How to use pin PD3 as TX and PD2 as RX?
I can send/receive data through serial monitor but I can not get any signal(output) when I connect pin PD3 and PD2 to oscilloscope.
Tx and Rx LED pins work fine.
Seems like Tx, Rx pins are by default configured as Digital Input/Output. How can I configure them to serve as Rx and Tx pin?
Please advice
Happy guy playing with Leonardo, real 'official' Leonardo board !!
What's your IDE version ? Is Leonardo in board's menu ?
Dis you try something like Serial1.begin() or Serialsomething.begin() ?
(32u4 is multiserial , so I suggest something like multiserial exemple for Mega, no more)
