I am being badly confused with terms like Rs232, TTL, interface, converter, protocol between PC and MCU in serial communication. I can't understand the difference between each of them.
I understand that if we want to send/receive data from MCU to PC or send/receive data from PC to MCU, we need a hardware circuit between PC and MCU. I think we call it hardware interface like usb to ttl, usb to rs232 interface between PC and MCU.
