Only lower data bus D 0 — D 7 is used as is 8-bit device. Pin Diagram of To make this website work, we log user data and share it with processors.

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

The angle x may be calculated as: Interrupt Structure of The count for rotating the shaft of the stepper motor through a specified angle may be calculated from the no. About project SlidePlayer Terms of Service.

The sequence of pulses can be decided, depending upon the required motion of the shaft. Modular Programming in Microprocessor.

Motorola Pins and Signals. Maximum Mode Configuration of Features of Programmable Interrupt Controller. It is fastest technique.


Intel CPU Structure. The CPU may drive these lines using output port lines in case of multichannel applications. Interfacing with The stepper motor has an internal delay of 10msec.

Intel A Programmable Peripheral Interface

Interfacing of with Debugging a Program in An operational amplifier is used as a current — to — voltage converter at the output of Intervacing Supporting Circuits of Microprocessor. It employs rotation of its shaft in terms of steps, rather than continuous rotation as in case of AC or DC motors.

Features of Microprocessor. An external feedback resister acts to control the gain. Address lines A 0 — A 1 are used by for internal decoding. Select your Language English.
