Simplex communication is a one-direction type of communication where the signal moves from one UART to another. Serial transmission of data through a single wire is actually more cost-effective than parallel transmission through multiple wires.Ĭommunication between two UART devices may be simplex, full-duplex or half-duplex. The second transmitter which is the receiver reassembles the bits into a complete byte. The transmitting UART takes bytes of data and transmits the bits in a sequential form. However, a predefined bit rate that is referred to as baud rate usually set in the flash memory of both microcontrollers for the instruction to be understood by both the devices. For example, two microcontrollers operating at different clock frequencies can communicate with each other easily via serial communication. The main advantage of this communication protocol is that its not necessary for both the devices to have the same operating frequency. The data transfers bit by bit digitally in form of bits from one device to another. It transfers data between devices by connecting two wires between the devices, one is the transmission line while the other is the receiving line. Universal Asynchronous Receive Transmit (UART) or Serial communication is one of the most simple communication protocols between two devices.
