A Tutorial on PIC18F Based Hardwar Design Using C Programming Language+

Shant Dilanian, Yumin L and Rajan Chandra

The objective of this tutorial is to use the PIC18F2221 Microcontroller and Microchip

development tools to design and implement a simple project. Specifically we develop C-code

in order to flash the LED is connected to the least significant bits of PORT B, RB0 (See Figure
