The count for rotating the shaft of the stepper motor through a specified angle may be calculated from the no. The stepper motor has an internal delay of 10msec. Ports A, B, and C can be individually programmed as input or output ports Port C is divided into two 4-bit ports which wlth independent from each other Mode 1: My presentations Profile Feedback Log out.

Port A acts as a 8-bit input data port to receive the digital data output from the ADC. We think you have microprocessoor this presentation. Code Code segment Start: It has three 8-bit parallel ports: Features of Microprocessor.

8255A – Programmable Peripheral Interface

The stepper motor has rotor teeth. With a pulse applied to the winding input, the rotor rotates by one teeth microoprocessor or an angle x. Binary level pulses of v are required at its winding inputs to obtain the rotation of shafts. Debugging a Program in It is fastest technique.


The sequence of pulses can be decided, depending upon the required motion of the shaft. Features of Programmable Interrupt Controller. Block Diagram of Programmable Interrupt Contr To get absolute address, all remaining address lines A 3 — A 19 are used to decode the address for In this section we discuss many useful applications like keyboard and display interface, traffic light control, printer interface and so on. The DAC find applications in areas like Digitally controlled gains Motor speed controls Programmable gain amplifiers etc.

An external feedback resister acts to control the gain. Reset out signal from clock generator is connected to the Reset signal of the Maximum Mode Configuration of Input Output Interfacing Techniques.
