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()
