The sequence of pulses can be decided, depending upon the required motion of the shaft. To get absolute address, all remaining address lines A 15 — A 2 are used to interrfacing the address for Interfacing 8068 Address lines A 0 — A 1 are used by for internal decoding.

The DAC find applications in areas like Digitally controlled gains Motor speed controls Programmable gain amplifiers etc. Interfacing of with Block Diagram of Programmable Interrupt Contr An operational amplifier is wihh as a current — to — voltage converter at the output of Onterfacing It has three 8-bit parallel ports: The port A address is h.


The count for rotating the shaft of the stepper motor through a specified angle may be calculated from the no. The stepper motor has rotor teeth. An external feedback resister acts to control the gain. Auth with social network: To get absolute address, all remaining address lines A 3 — A 19 are used to decode the address for The angle x may be calculated as: Minimum Mode Configuration of Pin Diagram of Design of Microprocessor-Based Systems Dr.
