In this series of PIC Microcontroller Communication, after learning on how PIC Microcontroller Communication with I2C, SPI, RS232 and USB can be achieved, in this article we are going to discuss the concepts of Ethernet Communication with PIC Microcontroller. When it comes to communication involving wires, Ethernet is the leading wired standard for networking as it enables to connect a very large number of computers, microcontrollers and other computer-based equipment to each other.
With just a switch, many different devices can easily communicate with one another with Ethernet, allowing devices and equipment to be accessed remotely and provides a cost-effective and reliable means of monitoring or controlling such equipment, for example a person could monitor several vending machines located in different places which can be several kilometers apart from the PC at the conform of your desk. A simple online interface to the vending machines can allow you to monitor everything from the internet.
