AVR GPIO TUTORIAL

December 28, 2013September 19, 2017 Sachin Y.P. Sharma

Keywords: AVR, GPIO, Atmega32 Every micro-controller has GPIO ports. GPIO stands for general purpose input output. These GPIO ports are used to take input on a micro-controller pin or output a value on micro-controller pin. We will learn how to use AVR ports and program them to read or write from port pins. Now the port has multiple pins associated with it. For example Atmega32 has 8-bit port, i.e. it has 8 pins in a single port. Each bit represents a pin i.e. bit 0 represents pin 0 on that…
