Asynchronous communication, there will be no clock signal required to send and receive data.Two types of serial communications are used one is synchronous and other one Asynchronous. ![]() Pin number three is transmission pin and pin number 4 is a receiver pin.UART communication pins of MSP430G2 launchPad are shown in figure.Transmitter wire is used to send data sequentially to other UART microcontroller or device.Receiver wire is used to receive data sequentially from other UART device.Serial communication consists of only two wires, transmission wire and receive wire.But speed come with cost, it required as many wires as many bits user want to transfer at a time. By parallel communication data can be transferred with high speed.There are other parallel communication protocols exists which are used to transfer data in parallel mode like 8 bit at time.UART can transfer data bit by bit serially. UART stand for Universal Asynchronous Receiver and Transmitter.How to receive data on UART of MSP430 microcontroller What is UART communication ?.How to transmit data through UART using MSP430 microcontroller.How to use UART communication of MSP430 microcontroller.
