Demonstration of a micro controller system, Computer Engineering

Assignment Help:

Within the Microelectronics centre we support the following microcontrollers 68HC11, 80C51 and the PIC16C5xx series; we have a set of software tools and emulators to help debug high and low level software /hardware designs. Within the demonstration we shall see a elementary program to chase lights on a parallel port (The knight rider car). The code is available in machine code and C as shown later. You will see the use of the compiler and assembler (IAR program) on a 68HC11 target machine.
         
C code Program
 
void main()

   Purpose : To Chase lights on port A 
   Target : 68HC11 microcontroller
   Version : 1.0
   Modifications : None

  unsigned char *Paddr,*Padr;
  unsigned char data;
  int x,i,del;
/* Declare the port a pointers */
 
  Padr = (unsigned char *)0x0;
  Paddr = (unsigned char *)0x1;
/* Port A all outputs */
 
  *Paddr =0xff;
  for(;;)
  {
    data = 0x1;
    for (i=0;i<=7;i++) /* Shift  8 times */
    {
    for (del = 0;del<=0x3fff;del++); /* Very long delay */
    *Padr = data<    }
  }  
}
