Motorola Pins and Signals. To rotate the shaft of the stepper motor, a sequence of pulses is needed to be applied to the windings of the stepper motor, in a proper sequence.

UNIT-IV PPI Various Modes Of Operation Interfacing To ppt video online download

To get absolute address, all remaining address 8806 A 3 — A 19 are used to decode the address for Code Code segment Start: Interrupt Structure of Interfacing with The stepper motor has rotor teeth. With a pulse applied to the winding input, the rotor rotates by one teeth position or an angle x. Interfacing of with It employs rotation of its shaft in terms of steps, rather than continuous rotation as in case of AC or DC motors.


The count for rotating the shaft of the stepper motor through a specified angle may be calculated from the no. Assume that the routine for this delay is already available. Supporting Circuits of Microprocessor. Select your Language English.

8255A – Programmable Peripheral Interface

Modular Programming in Microprocessor. Out of these inteffacing inputs only one can be selected for conversion by using 3 address lines A,B,C. It has three 8-bit parallel ports: The port A address is h. Operating Modes of Features of Programmable Interrupt Controller. In this section we discuss many useful applications like keyboard and display interface, traffic light control, printer interface and so on.

Design of Microprocessor-Based Systems Dr. Your email address will not be published. The sequence of pulses can be decided, depending upon the required motion of the shaft.

It is fastest technique. By using indirect address method this range can be extended upto 2 16 addresses. Intel CPU Structure. Input Output Interfacing Techniques. Features of Microprocessor.

Reset out signal from clock generator is connected to the Reset signal of the The DAC find applications in areas like Digitally controlled gains Motor speed controls Programmable gain amplifiers etc. Binary level pulses of v are required at its winding inputs to obtain the rotation of shafts.
