Descibe 8086 interfacing of stepper motor to rotate it through 90 degree using 8255?
To interface a stepper motor with the 8086 microprocessor using the 8255 Programmable Peripheral Interface (PPI), you first configure the 8255 in mode 0 for simple I/O operations. The control lines of the stepper motor are connected to the output ports of the 8255. The microprocessor sends a sequence of pulses to these ports to energize the motor coils in the correct order, effectively rotating the motor in steps. To achieve a 90-degree rotation, the number of pulses sent corresponds to the required steps based on the step angle of the motor (e.g., for a 1.8-degree stepper, you would send 50 pulses).

How do you change a degree of rotation in stepper motor using 8085 microprocessor?
To change the degree of rotation in a stepper motor using an 8085 microprocessor, you first need to determine the number of steps required for the desired rotation. This is done by calculating the steps per degree based on the stepper motor's specifications. Then, you can write a program in assembly language to control the motor's step sequence using output ports connected to the motor driver. By sending the appropriate sequence of signals for the calculated number of steps, you can achieve the desired rotation.

Transfer function of stepper motor?
A stepper motor has a transfer function. The exact function is determined by a motor's individual characteristics. The speed at which it is capable of repeating a position is based on its geometric configuration and size.

What is stepper moto?
A stepper motor is a type of electric motor that divides a full rotation into a series of discrete steps, allowing for precise control of angular position and speed. Each step corresponds to a specific degree of rotation, enabling accurate positioning without the need for feedback systems. Stepper motors are commonly used in applications such as 3D printers, CNC machines, and robotics, where precision and repeatability are essential. Their ability to maintain position when powered makes them ideal for open-loop control systems.
