What ismaster-slave communications

Master-Slave Communications is a configuration where one side, known as the master, initiates control and transmission, while the other side, called the slave, follows the instructions provided by the master. This configuration frequently uses polling to start data transmissions. In this communication model, a single device or process, known as the master, controls one or more devices or processes, which are called slaves. The master device serves as the communication hub for the other devices or processes in the network.

I2C and SPI are widely used communication buses in modern designs for simple master-slave communications. In I2C, the master can communicate with several slaves by selecting them through their unique addresses; while in SPI, each slave has a dedicated chip select line for communication initiation.


What is polling in Master-Slave Communications?

Polling refers to the process of sending a signal from the master device to the slaves inquiring if they have any data to transmit. The slaves then respond with either a positive or negative response.

What are the advantages of Master-Slave Communications?

The advantages of Master-Slave Communications include reliable data transfers, simplified network management, and cost-effectiveness.

Final Thoughts

Master-Slave Communications is a widely-used configuration for effective data transmissions. By understanding this communication model, users can build reliable, efficient networks that are easy to manage.
