The angle x may be calculated as: Timers and Counters in Microcontroller.

To get absolute address, all remaining address lines A 15 — A 2 are used to decode the address for Feedback Privacy Policy Feedback. Interrupt Structure of To use witn website, you must agree to our Privacy Policyincluding cookie policy. Features of Microprocessor. An operational amplifier is used as a current — to — voltage converter at the output of AD By using indirect address method this range can be extended upto 2 16 addresses.

The sequence of pulses can be decided, depending upon the required motion of the shaft. To make this website work, we log user data and share it with processors.

Input Output Interfacing Techniques. If you wish to download it, please recommend it to your friends in any social system. Modular Programming in Microprocessor. Assume that the routine for this delay is already available.


Intel CPU Structure.

Your email address will not be published. Address lines A 0 — A 1 are used by for internal decoding. Pin Diagram of Maximum Mode Configuration of Only lower data bus D 0 — D 7 is used as is 8-bit device.

Draw and explain interfacing of with I/O mapped I/O mode.

Binary level pulses of v are required at its winding inputs to obtain the rotation of shafts. Block Diagram of Programmable Interrupt Contr 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 intrfacing other Mode 1: 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. Interfacing with Reset out signal from clock generator intwrfacing connected to the Reset signal of the Port A acts as a 8-bit input data port to receive the digital data output from the ADC.

Minimum Mode Configuration of Design of Microprocessor-Based Systems Dr. My presentations Profile Feedback Log out. Share buttons are a little bit lower. To rotate the shaft of the stepper motor, a sequence of pulses is needed to be applied to the windings of the stepper motor, interfacjng a proper sequence.

Motorola Pins and Signals. Features of Programmable Interrupt Controller.


Types of Interrupts. We think you have liked this presentation.

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

To get absolute address, all remaining address lines A 3 — A 19 are used to decode the address for Select your Language English.

The port A address is h. Auth with social network: Code Code segment Start: Operating Modes of The DAC find applications in areas like Digitally controlled gains Motor speed controls Programmable gain amplifiers etc. Leave a Reply Cancel reply Your email address will not be published. Published by Derick Warren Modified over 3 years ago.

Debugging a Program in It is fastest technique. Out of these 8 inputs only one can be selected for conversion by using 3 address lines A,B,C. The CPU may drive these lines using output port lines in case of multichannel applications.

Registration Forgot your password? CWR address is 86h. In this section we discuss many useful applications like keyboard and display interface, traffic light control, printer interface and so on. Interfacing of with It has three 8-bit parallel ports: An external feedback resister acts to control the gain.
