Question

Question 2 Write a C language program for the EVBPIus2 evaluation board that uses an interrupt service routine to read the analog value on pin PEO every 0.3ms. Write this value to the PORTB LED?s. Your program should be sufficiently complete to compile and run on the EVB Plus 2 evaluation board. Use good programming practice (comments, self-documenting variable names, functions etc.) to make your code more ?readable?. As in the laboratory, you can assume that register and interrupt service routine definitions are provided for you in header files named 106811 .h and 1NT68 11 .h respectively. Your C code should be as simple as possible. [30]

Explanation / Answer

CONCEPT:

C program to use Routine Interrupt Service

CODE:

#include<stdio.h>

#include<stdlib.h>

#include<conio.h>

#include<iostream>

#include<math.h>

    //Chip Settings

    __CONFIG(1,0x0200);

    __CONFIG(2,0X1E1F);

    __CONFIG(3,0X8100);

  __CONFIG(4,0X00C1);

    __CONFIG(5,0XC00F);

   unsigned char counter=0;

    void main()

  {

      //Setup Timer0

      tyop=1; // is divide by 256

      tyop1=1;

     tyop2=1;

       psd=0;      //Timer Clock Source

    ticf=0;     

      t689f=1;   //8 BIT MODE

       t6rye=1;   

     poiju=1;     //Enable Peripheral Interrupt

       GIE=1;      //Enable INTs globally

     trmeio=1;      

       //Set RB1 as output because we have LED on it

       TRISB&=0B11111101;

       while(1);   

interrupt ISR();

printf(
