I have a question on UART.
Why is UART limited to certain pins on the AVR?
Back in my PIC days ( like 3 months ago , lol ) I was able to achieve TTL serial communication on any pin . It seems that with the AVR UART is only on certain pins. Well serial is just a combination of 1 and 0 , so shouldn't serial be possible on any output pin?
Can someone clear this up for me ?
