Basics
For this tutorial we will a connect a switch to PORT C0 and LED to PORT B0 of Atmega32. W will configure PORT A0 as input to read the switch status and PORT C0 as outputto display the switch status on LED. Initially LED will be ON , when we press switch the LED will be OFF.
Refer the AVR I/O Register Configuration tutorial for basics of GPIO register configuration.
