#Benefits of serial communication protocol software

Serial data and address, Bus connection with software addressing Serial data, Bus connection with hardware selection Disks are also connected via special parallel ports (e.g., SCSI or IDE). The most common type of parallel port is a printer port (e.g., a Centronics port that transfers 8 bits at a time). There will usually be some control signals on the port that indicate when data are ready to be sent or received. A parallel port carries 1 bit on each wire, thus multiplying the transfer rate obtainable over a single wire. Data are transferred in or out in parallel, that is, on more than one wire. The serial port is usually connected to an integrated circuit called a UART that handles the conversion between serial and parallel data.ДЄ parallel port is an interface for a computer to communicate peripherals in parallel manner. Smaller connectors (e.g., 9-pin D-type) carrying a subset of RS-232 are often used on personal computers.

The most common type of serial port is a 25-pin D-type connector carrying RS-232 signals. Usually, a serial mouse is connected to COMI (communication port 1). A serial port is an interface through which peripherals can be connected as a communication channel using a serial (bit-stream) protocol. In general, there are two types of communication ports in a computer: serial ports and parallel ports. Morris Chang, in The Electrical Engineering Handbook, 2005 Serial Port and Parallel Port Compare the cost of each system and suggest an advantage of the masterвЂ“slave system over the single controller solution proposed in Activity 2. Select suitable chips for the master and slave controllers, and list the connections required. Sketch a block diagram for an alternative implementation of the robot controller in Activity 2 above, using a separate controller for each axis connected to a master SPI controller. Outline how the controller will move the robot between programmed positions.

Download the data sheet and draw a block diagram for the system, identifying the pins that should be connected to the motors and encoders. Select the most suitable chip from the Microchip website that could be used as a controller for the robot positioning system.

A block of EEPROM is needed to store up to 128 programmed positions, requiring a 16-bit code for each axis for each position.

Each has a PWM speed controlled motor and an incremental encoder with three digital outputs providing the position feedback. 2.ДЄ robot has four axes to be controlled by a PIC MCU. Summarize the features of each, and suggest a typical application for each device. In addition, serial communication is one of the cheapest modes of communication that can be implemented, and over long-haul communication, it can provide numerous benefits.Download the data sheet and study the summary page for the PIC 12F675, 16F690 and 18F8720. Nevertheless, the clock skew problem that often happens between different channels of communication is not an issue with serial communication.Д¬ompared to parallel communication, serial communication has better signal integrity. The data transfer rate, however, may be low in comparison to parallel communication. Interconnecting cables are fewer, and there is no need for a serializer/deserializer in any case. As there are fewer conductors in contrast to parallel communication, the cross-talk issue is significantly less. There are several advantages with serial communication. It is also popular in computer devices, peripheral devices and integrated circuits, which are provided with one or more serial ports, resulting in no additional hardware requirements for serial communication. It is the most popular mode of communication protocol for most instrumentation devices.

In contrast to parallel communication, which is half duplex, serial communication is full duplex, i.e., transmission and receipt of signals can occur simultaneously.
