Uart serial communication protocol
For example, a 32-bit parallel communications medium such as conventional PCI (Peripheral Component Interconnect) would send 32-bits of data per clock cycle. Parallel communication, on the other hand, is sending multiple bits of data at the same time over a given communications bus. One of the advantages of serial communication is that data can be transmitted at higher frequencies, therefore increasing the amount of data that can be sent despite the fact that less data is sent at once when compared to parallel communication. While RS-232 (note that UART is commonly used for RS-232) and RS-485 are the two protocols we most commonly associate with the term “serial communication”, many other modern technologies such as USB (Universal Serial Bus), SATA (Serial ATA), and Firewire/IEEE 1394 are also serial protocols. Serial communication in simple terms is sending data a single bit at a time over a given communications bus. We will provide a crash course on those two topics here. To understand what a UART does in more detail, it is useful to understand serial communication and parallel communication. At a high-level, a UART is simply a microchip that enables communications between a computing device (PC, embedded system, etc) and other equipment. UART stands for Universal Asynchronous Receiver Transmitter. In this piece, we will explain what UART and SPI are, explain the differences between UART vs SPI, discuss some common applications that use UART and SPI, and provide you with information to help you get started with debugging and programming embedded systems that use UART or SPI. UART and SPI are important aspects of embedded systems design and development, and understanding the differences between them will help you better understand how the systems that use them work. If you work with embedded systems, understanding the differences between the various technologies and protocols these systems use is important.
