Help me in my CCS SourceCode

[glenjoy]

Hi,

Can someone help me verify my code, sometmes this code resets and it creates warnings when I compile it with Microchip MPLAB IDE but no warnings in CCS.

Here is the code:

#include "C:\Documents and Settings\COA\My Documents\PIC Projects\Line_PIC\Line_PIC.h"

void Start();
void Run();
void TurnRight();
void TurnLeft();
void Forward();
void Reverse(char speed);



unsigned char high,low,flag,time;

#byte A_PORT=0x05
#byte B_PORT=0x06


void main()
{

   port_b_pullups(TRUE);
   setup_timer_0(RTCC_INTERNAL|RTCC_DIV_1);
   setup_timer_1(T1_DISABLED);
   setup_timer_2(T2_DISABLED,0,1);
   setup_comparator(NC_NC_NC_NC);
   setup_vref(FALSE);

   SET_TRIS_A( 0xFF );
   SET_TRIS_B( 0x40 );

   A_PORT = 0xFF;
   B_PORT = 0x43;

   high = 80;
   low = 30;
   flag = 0;
   time = 100;
//   Start();
   while(1)
         {
         A_PORT |= 0x0F;
         Run();
         }

}

Start()
{
   char exit,key;
   exit = 1;
      while(exit)
      {
      key = B_PORT;
      if((key & 0x40) == 0)
      exit = 0;
      }
}


Run()
{
   char sensors;
   sensors = (A_PORT &= 0x0F);

   if((sensors & 0x01) == 0) // Turn Right
   {
   TurnRight();
   flag = 1;
   }

   else if((sensors & 0x08) == 0) // Turn Left
   {
   TurnLeft();
   flag = 2;
   }

   else if(sensors == 0x09) // Forward High
   {
   Forward();
   flag = 0;
   }

   else if(((sensors == 0x0B) || (sensors == 0x0D)) && (flag == 0))  // Forward Low
   {
   Forward();
   }
}

Forward()
{
   B_PORT = 0x67;

   delay_ms(time);
}

TurnRight()
{
   B_PORT = 0x6B;

   delay_ms(time);
}

TurnLeft()
{
   B_PORT = 0x57;

   delay_ms(time);
}

Reverse(char speed)
{
   B_PORT = 0x5B;

   delay_ms(time);
}

Thanks.

Hi,

What are those warnings?
What is the reset reason?
(You should check it immediately after boot up,
it can caused by stack owerflow, user, etc.)
(example: RCON Register on a 18F8x20)

regards
Zed

replace string #byte by #define

Hi glenjoy,

1)
You didn't post the full header, it is important to see how do you define some pre-processor directives.
We doesn´t know wich microcontroller, oscillator type and Configuration Word are you using.

2)
#byte A_PORT=0x05
#byte B_PORT=0x06
Are Ok. Using #byte a C variable is created and mapped to hardware registers.
