PIC18f4580 Serial Communication Tutorial Basics of Serial Communication: When a microprocessor connects with the outside world, it offers the data in byte-sized chunks. In particular cases, such as printers, the information is simply taken from the 8-bit data bus and offered to the 8-bit data bus of the printer. This can work only if the cable is not too long, because long cables reduce and even distort signals. Moreover, an 8-bit data path is expensive. Keeping this in mind, serial communication is used for transmitting data between two systems situated at distances of hundreds of feet to millions of miles apart. serial versus parallel data transfers. One will simply analyze major distinction between serial and parallel communication topologies. Parallel communication within which a lot of connections and so on associative hardware as a result of in parallel communication technique it transmits every bit at he same time. In contras...
