One of such technologies is the multiple address radio system (MAS). Leased telephone circuits, fiber, and satellites, however, have a comparatively high cost, and new radio technologies offer an attractive communications solution. Serial communications to outstation devices can be implemented through several media: copper wire (RS485/RS232), fiber, radio, leased line, and even satellite. Gabbar, in Smart Energy Grid Engineering, 2017 18.9.4 Host to Outstation Hardware Communications An example project is given where two Nucleo development boards communicate via a UART interface. This chapter presents the Nucleo-F411RE development board UART GPIO pins. In the RS232 protocol, a logic HIGH is defined to be at –12 V, and a logic 0 is at + 12 V. Data in serial asynchronous communication can either be sent using the standard RS232 protocol or two devices can simply be connected together provided they satisfy the logic gate interface rules (e.g., TTL to TTL, or TTL to CMOS, etc.). In this standard data is sent over a single line from a transmitting device to a receiving device in bit serial format at a prespecified speed, also known as the Baud rate, or the number of bits sent each second. The most commonly used serial communication method is based on the RS232 standard.

Serial communication is a simple means of sending data to long distances quickly and reliably. These enable a microcontroller to interface to other compatible devices easily.ĭogan Ibrahim, in ARM-Based microcontroller projects using MBED, 2019 Abstract Some microcontrollers (e.g., PIC18F series) incorporate a serial peripheral interface (SPI) or an integrated interconnect (I 2C) hardware bus interface.

Icc serial communication protocol series#

The PIC18F series of microcontrollers have built-in USART modules.

If serial I/O hardware is not provided, it is easy to develop software to implement the serial data communication using any I/O pin of a microcontroller. The baud rate and the data format can usually be selected by the user program. Some microcontrollers have built-in hardware called universal synchronous-asynchronous receiver-transmitter (USART) to implement a serial communication interface.

Icc serial communication protocol Pc#

For example, a microcontroller can be connected to another microcontroller or to a PC and exchange data using the serial communication protocol. Serial communication (also called RS232 communication) enables a microcontroller to communicate with other devices using the serial RS232 communication protocol. Let us begin by examining the first level of interaction with the transmission medium itself – the physical layer and its specifications.ĭogan Ibrahim, in SD Card Projects Using the PIC Microcontroller, 2010 1.3.10 Serial I/O

It is important to understand these layers in order to comprehend the various other protocols. The first layers of the OSI model include functions of the physical, data link, and network layers. The engineering department of the EIA issued the EIA-232 interface standard in the United States in 1969. EIA-232 was particularly developed for interfacing data terminals to modems. The EIA-232 interface standard was developed for interfacing data terminal equipment (DTE) and data circuit terminating equipment (DCE) (earlier called as Data Communication Equipment) employing serial binary data interchange. This book uses the common notation of “RS232.” This standard, developed by the Electronic Industry Association and the Telecommunications Industry Association (EIA/TIA), is more popularly referred to simply as “RS232” where “RS” stands for “recommended standard.” In recent years, this suffix has been replaced with “EIA/TIA” to help identify the source of the standard. EIA/TIA-232-E specification is the most popular serial communications standard. Serial communications is used extensively within the electronics industry due to its relative simplicity and low hardware overhead (as compared to parallel interfacing).
