The UART only deals with the serial data. It knows nothing about the actual voltages used to transmit the data.The UART generates a serial stream of data bits.
RS232, RS422, RS485 etc. describe the voltages to be used and the wiring arrangement between the transmitter and receiver.
See and that is what i dont understand. Just looking at some pages on the interest, a UART is defined by a single tX and single RX? isnt it? that is what i have seen.That's just two different methods of sending the same signal.
Differential or single-ended has nothing to do with the UART protocol.
No.So if that is the case, then a UART does define the physical or electrical interface
UART does not define the method of transmission and data format etc.See and that is what i dont understand. Just looking at some pages on the interest, a UART is defined by a single tX and single RX? isnt it? that is what i have seen.
