About project SlidePlayer Terms of Service. Block Diagram of Programmable Interrupt Contr The CPU may drive these lines using output port lines in case of multichannel applications.

Select your Language English. An external feedback resister acts to control the gain.

UNIT-IV 8255 PPI Various Modes Of Operation Interfacing To 8086.

Motorola Pins and Signals. The port A address is h.

Auth with social network: Out of these 8 inputs only one can be selected for conversion by using 3 address lines A,B,C. Only lower data bus D 0 — D 7 is used as is 8-bit device. Intel CPU Structure. OK Programmable Interval Timer. To make this website work, we log user data and share it with processors. Modular Programming in Microprocessor. Reset out signal from clock generator is connected to the Reset signal of the It employs rotation of its shaft in terms of steps, rather than continuous rotation as in case of AC or Microproceszor motors.


Operating Modes of CWR address is 86h. Supporting Circuits of Microprocessor.

Assume that the routine for this delay is already available. Interfacing of with Design of Microprocessor-Based Systems Dr. The stepper motor has an internal delay of 10msec. Maximum Mode Configuration of To get absolute address, all remaining address lines A 3 — A 19 are used to decode the address for 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: Registration Forgot your password?

My presentations Profile Feedback Log out. With a pulse applied to the winding input, the rotor rotates by one teeth position or an angle x. The angle x may be calculated as: By using indirect address method this range can be extended upto 2 16 addresses. Interrupt Structure of Pin Diagram of Timers and Counters in Microcontroller. Features of Microprocessor. Features of Programmable Interrupt Controller.


In clockwise 5 rotations In anticlockwise 5 rotations. Interfacing with The stepper motor has rotor teeth. It has three 8-bit parallel ports: 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.

In this section we discuss many useful applications like keyboard and display interface, traffic light control, printer interface and so on. Feedback Privacy Policy Feedback.
