SSH

Accessing Raspberry Pi through SSH

SSH stands for Secure Shell. It is a secure channel created over an insecure network. The channel consists of a server and a client. This channel uses public key cryptography and can be used for secure transmission of passwords, remote log in, command execution etc.. SSH can be used when we cannot physically access the Raspberry Pi due to various reasons like the USB ports are engaged or the board is in a remote location. This method also minimizes hassle of...

UART Communication

Using UART of PIC Microcontroller – MPLAB XC8

UART stands for Universal Asynchronous Receiver / Transmitter. It is a very popular serial communication interface which provides Full Duplex communication between two devices. UART uses two data lines for sending (TX) and receiving (RX) data. Ground/Reference of both devices should be made common. As the name indicates it is an asynchronous communication interface, which means that it doesn't need to send CLOCK along with data as in synchronous communications. UART is the communication interface used by our old computer's...
