1. Develop a program in low level language or assembly language that can control the stepper motor to run in forward direction in 2 phase excitation mode. Draw the diagram for stepper driver circuit using transistors and winding connection. Motor has to be connected in port B. Write the control word value of 8255. Port address Port A = FFF8H, Port B =FFFAH, Port C= FFFC H, control word Register = FFFEH (Diagram, main Program marks, delay program marks, control word 1 marks = 5 marks) 1.
