Question

I need code for the HCS12 Dragon trainer plus 2 that allows me to read values from its built in temperature sensor and displays those values on the seven segment displays .

Answer 1

a) After deleting everything in the main.c,
b) Then you have to copy and paste the program into the main.c,
c) to make F7 to download F5 and to run F5 and then execute it

#include <hidef.h>   //--com. define, macros 
#include "derivative.h"      // --derivative-specific-definitions 
void MSdelay(unsigned int);
void main(void) {
    DDRB = 0xFF;    //--PORTB as o/p
    DDRJ = 0xFF;    //--PTJ as o/p for Dragon12+ LEDs
    PTJ=0x0;        //--Allow these LEDs. to. dsiplay. data. on. PORTB. pins.
    ATD0CTL2 = 0x80;     //--Turn on ADC,..No... ..Intr
    MSdelay(5);
    ATD0CTL3 = 0x08;  //--one. conversion., there. is. no. FIFO.
    ATD0CTL4 = 0xEB;  //--8-bit resolution, 16-clock. for. 2 phase.,

                      //--prescaler of 24 for the Conversion of Frequency=1MHz  
    for(;;)
    {
    ATD0CTL5 = 0x85;  //--Channel-5 (right-justified, unsigned&single-conver,one-chan only)
   while(!(ATD0STAT0 & 0x80));
    PORTB = ATD0DR0L;  //--dump it on the LEDs
   MSdelay(2);   //--optional
   }

  }

 void MSdelay(unsigned int itime)

  {

    unsigned int k; unsigned int l;

    for(k=0;k<itime;k++)

      for(l=0;l<4000;l++);

  }
