![]() There is only one communication line, thorough which bits are transmitted sequentially.ĭata can be transmitted using Parallel or Serial techniques, as the pros and cons of two methods are equal and the selection depends on application. In Serial Transmission only one bit of a byte is transmitted at a time. Serial Transmission Serial Data Transmission Thus for 8-bit data transfer we need 8 dedicated lines as shown above. In parallel communication an entire byte of data is transmitted at a time. Parallel Transmission Parallel Data Transmission We have two options to transmit data through transmission lines. PIC to PIC communication will be needed in some embedded applications. 2 USART – Universal Synchronous Asynchronous Receiver Transmitter. ![]()
