The objective of this practical assignment is to familiarize the learner with some of the PIC microcontroller commands and to learn how fixed time delay routines are generated. Fixed time delay routines are used quite often in a variety of I/O interfacing tasks such as switch contact debouncing, periodic pulse width generation, slowing down of micro-controller for human interfacing etc... PROGRAM DESCRIPTION: 1. Making use of MPLAB IDE, write firmware code to switch all LED's connected to port pins RD0-RD7 continuously on for one second and then off for one second. 2. First use a flowchart to determine the program structure and then generate your commented firmware source code.
