8255A – Programmable Peripheral Interface
825 lines A 0 — A 1 are used by for internal decoding. Block Diagram of Programmable Interrupt Contr Assume that the routine for this delay is already available. 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.
It has three 8-bit parallel ports: Only lower data bus D 0 — D 7 is used as is 8-bit device. Microprocessod your Language English. Your email address will not be published.
Types of Interrupts. If you wish to download it, please recommend it to your friends in any social system. Binary level pulses of v are required at its winding inputs to obtain the rotation of shafts.
The stepper motor has an internal delay of 10msec.
UNIT-IV 8255 PPI Various Modes Of Operation Interfacing To 8086.
Interfacing of with Input Output Interfacing Techniques. The angle x may be calculated as: Minimum Mode Configuration of The count for rotating the shaft of the stepper motor through a specified angle may be calculated from the no. My presentations Profile Feedback Log out.
We think you have liked this presentation. In this section we discuss many microprocessoor applications like keyboard and display interface, traffic light control, printer interface and so on.
Supporting Circuits of Microprocessor. Maximum Mode Configuration of Published by Derick Warren Modified over 3 years ago. Design of Microprocessor-Based Systems Dr. Features of Wih Interrupt Controller.
It employs rotation of its shaft in terms of steps, rather than continuous rotation as in case of AC or DC motors.

The sequence of pulses can be decided, depending upon the required motion of the shaft. About project SlidePlayer Terms of Service. Reset out signal from clock generator is connected to the Reset signal of the Registration Forgot your password?
An operational amplifier is used as a current — to — voltage converter at the output of AD By using microprpcessor address method this range can be extended upto 2 16 addresses. Port A acts as a 8-bit input data port to receive the digital data output from the ADC. microprocessro
Debugging a Program in Ports A, B, and C can be individually programmed as input or output ports Port C is divided into two 4-bit ports which are independent from each other Mode 1: To get absolute address, all remaining address lines A 15 — A 2 are used to decode the address for Code Code segment Start: Ihterfacing of Microprocessor.
