EE 315: Microprocessor Laboratory

First Day in the Lab

On the first day of the lab, find out the following information about the kits that you will be using during the semester and note these in your lab notebook.

1. The memory map of system. In addition to helping you decide the location of your program, this will also be used to initialize the stack.

2. The hardware components like PPI, Timer, Display Controller, USART etc, that are available on the system.

3. Crystal and system clock frequency.

4. Addresses for the ports of the various devices that are available on the system.

5. Familiarize yourself with the keypad and the functions of the various keys and their usage.

The monitor in the kit allows you to do the following using specific function keys.

1. Examine / modify a specified memory location.

2. Examine and change the contents of various registers of the 8085.

3. Run / execute a program.

4. Single Step through the program. Program is executed one instruction at a time (not one byte at a time!).

5. Set break points in the program.

6. Move blocks of memory from one position in the address range to another.

Check to see if the kit provides any other function and note them in your lab notebook.

In addition to the above, the kit also has a few subroutines that can be used to perform some functions. The addresses for few often used subroutines are given in Anshuman Kit Details .Write small programs to use the following subroutines.

1.Display a character in "address" and "data" fields of the seven-segment display.

2.Read character(s) from the keypad

3.Introduce a specified delay in the programs.

Programs for problems in S/W-1 to S/W-3 will have to be written and tested on simulator (available on lab web site) in advance before coming to lab.
Note: Display programs can not be tested on the simulator.
