Out of these 8 inputs only one can be selected for conversion by using 3 address lines A,B,C. Interrupt Structure of Interfacing interdacing with Supporting Circuits of Microprocessor.

The count for rotating the shaft of the stepper motor through a specified angle may be calculated from the no. With a pulse applied to the winding input, the rotor rotates by one teeth position or an angle x. Auth with social network: Address lines A 0 — A 1 are used by for internal decoding. Feedback Privacy Policy Feedback. The angle x may be calculated as: 88086 sequence of pulses can be decided, depending upon the required motion of interfacin shaft.

Port A acts as a 8-bit input data port to receive the digital data output from the ADC. In clockwise 5 rotations In anticlockwise 5 rotations.
