Question

1. Develop a program in low level language or assembly language that can control the 230 V motor to run in forward direction for few minutes and switch off the motor for few minutes. Draw the diagram for relay driver circuit using transistors. 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

Step 1

We need to develop a program in a low-level language (assembly language) that controls a 230V motor. The motor should run in the forward direction for a few minutes, then switch off for a few minutes. This process is to be controlled using the 8255 Programmable Show more…

Develop a program in low-level language or assembly language that can control the 230V motor to run in the forward direction for a few minutes and switch off the motor for a few minutes. Draw the diagram for the relay driver circuit using transistors. The motor has to be connected to port B. Write the control word value of 8255. Port address PortA = FFF8H, PortB = FFFAH, PortC = FFFCH, control word register = FFFEH.
