Q1. Interpolationv (MATLAB PROGRAM ) :

Suppose that x = 0:10;?

y = [1.5, 1.0, 0.9, 2.6, 2.2, 0.03];?

a)Use both linear interpolation and cubic spline interpolation function to determine the value of y when x= 3.5

b) Plot both functions y and the interpolated version of y.

To develop a program for the PIC 16F84A using either MPLAB X IDE simulator software. T

he PIC 16F84A has 8 LEDs connected to Port B. The program is to convert your student number (10 ASCII characters), taken in reverse order, one character at a time, to Gray code.

Each converted character is to be displayed on 4 of the LEDs connected to Port B (B0 to B3) of the microcontroller.

Further, each converted character will be displayed for 3 seconds, with the LEDs turned OFF for 1 second between each character. Once all characters have been displayed the program will continue to run with all of the Port B LEDs flashing in a pattern of Odd Numbered LEDs On and Even Numbered LEDS Off for 1 second, and then Odd Numbered LEDs Off and Even Numbered LEDS On for 1 second. This pattern will repeat indefinitely.
