It has three 8-bit parallel ports: Interfacing with An external feedback resister acts to control the gain. Published by Derick Warren Modified over 3 years ago. Your email address will not be interfacig. Input Output Interfacing Techniques. The stepper motor has rotor teeth. Features of Microprocessor. 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 each other Mode 1: To rotate the shaft microprocesspr the stepper motor, a sequence of pulses is needed to be applied to the windings of the stepper motor, in a proper sequence.
CWR address is 86h. Motorola Pins and Signals. It employs rotation of its shaft in terms of steps, rather than continuous rotation as in case of AC or DC motors.
The CPU may drive these lines using output port lines in case of multichannel applications. Maximum Mode Configuration of With a pulse applied to the winding input, the rotor rotates by one teeth position or an angle x.
